Best Pool Thermometer | Buyer’s Guide

If you’re a newbie or just starting out, then definitely, you can’t afford to skip this section.

Moving further, we would be having an in-depth discussion on almost all the essential parameters that you might be looking for in your favorite pool thermometer.

Thermometer Types

Mainly, there are two types of thermometers, that is, digital and analog.

Depending upon your requirement and budget, you can opt for any one of the two.

Needless to say, each of them has its own advantages and disadvantages.

Analog Thermometer

The analog thermometer is the traditional one that works on the principle of expansion and contraction of mercury.

As your pool water temperature will surge, the metal will expand upward.

On the other hand, when the temperature drops, the metal strip will contract and move downward.

It will stop when it reaches the temperature of the surrounding.

Digital Thermometer

As the name suggests, a digital thermometer would read the temperature of the pool water and display it digitally on a screen.

In most cases, the digital thermometer uses a probe or something sort of that which sits below the surface of the water and monitors the temperature.

The temperature on the screen would change to reflect the temperature of the probe.

Moreover, there are digital thermometers available on the market that are wireless.

Nowadays, there are digital thermometer models available on the market that can be used with an Android or iOS app.

In case, you don’t want to own a separate unit for reading the temperature then you can use your smartphone to monitor the temperature of your swimming pool.

If features such as “versatility” are your top priority then definitely, the floating pool thermometers are the ones that you should opt for.

The floating thermometers are easy to use, and you can remove them without any hassle once you’re done with the pool water temperature reading.

But, at the same time, in the context of accuracy, hanging thermometers are the better choice.

In terms of lifespan, a floating pool thermometer would be a better bet as compared to the hanging counterpart.

Digital Vs. Analog

In terms of accuracy, a digital thermometer will score higher as compared to its analog counterpart because the former comprises advanced sensors which an analog thermometer lacks.

Since the digital thermometer comes with a large reading screen so the probability of error would be far less as compared to its analog counterpart.

On the other hand, you might misread the temperature reading in the case of an analog thermometer if you’re holding it at an angle.

In layman’s language, digital thermometers are more technology-driven and thus, are comparatively expensive.

On the contrary, an analog thermometer doesn’t come with any fancy sensor or electronics inside it so the probability is high that it will last longer.

If you’re keeping the digital thermometer for a longer duration in your pool then you can’t negate the possibility of it breaking down.

Nonetheless, proper and regular maintenance will definitely increase the lifespan of both digitals as well as an analog thermometer.

Solar Powered Vs. Battery Powered

It’s quite obvious that solar-powered floating thermometers would be far more cost-efficient as compared to their battery-powered counterpart, isn’t it?

If you’re using energy from the sun then definitely, you’ll save a good amount of money in the long run as well all know that sunlight is a free source of energy, right?

If you’re a pool owner like me who wants to take advantage of the free resource then definitely, you’ll opt for a solar-powered floating thermometer, right?

But, at the same time, you should also keep in mind that solar-powered thermometers are expensive so if you’re on a shoestring budget then it might not be the best bet for you.

I totally agree that a solar-powered thermometer comes with a huge upfront cost but at the same time, in the long run, it would be more economical than its battery-powered counterpart.

On the contrary, battery-powered thermometers are cheaper to buy, but at the same time, you shouldn’t forget that the battery needs to be changed now and then.

So, you should also inculcate the cost of the battery when you’re comparing the cost of the solar-powered and battery-powered thermometers.

Nevertheless, the cost of a battery can be drastically reduced if you’re buying a thermometer that comes with a rechargeable battery.

Frankly speaking, I prefer a solar-powered thermometer as it is eco-friendly.

In simple words, the solar-powered thermometer can’t be held responsible for draining any of our finite energy sources.

Exposure to Water and Chemicals

Whether you’re planning to buy a Milliard pool thermometer or a Pentair pool thermometer, you want them to last longer, right?

A Flamingo pool thermometer or any other pool thermometer is not the same as a traditional thermometer that is used for a couple of minutes and then kept in safe storage.

To be honest, a lot many pool thermometers are used on a regular basis to give real-time updates on the temperature of the pool.

Not only are the pool thermometers exposed to the pool water but also the chemicals present in it.

And, at times, the pool chemicals can be held responsible for breaking down or malfunctioning the swimming pool thermometer.

For example, pool water might get into the thermometer leading to its malfunctioning.

Similarly, prolonged exposure to direct sunlight can be a cause of concern for the swimming pool thermometer.

Material Used

It goes without saying that the top-rated swimming pool thermometers are known for their unique design, features, as well as materials that they comprise.

High-quality thermometers are costlier than others because they use superlative materials for building top-rated pool thermometers.


I always suggest my clientele NOT buy a solar pool thermometer or a wireless pool thermometer that doesn’t come with a warranty.

Always look for the floating pool thermometers that come with a longer duration of warranty as it depicts the confidence of the manufacturer in its offering.

As per my knowledge and experience, what I can say is, opt for a pool thermometer that comes with at least a one-year warranty.


I know many of my readers would be wondering that a pool thermometer is an accessory in itself, right?

But, at the same time, you would be astonished to know that the premium and top-rated swimming pool thermometer comes with additional accessories as well.

Frankly speaking, there isn’t anything wrong to opt for a simple floating thermometer that would only show the pool water temperature reading and doesn’t come with any additional extra features.

On the other hand, advanced pool thermometers are more than just displaying the temperature.

If I had to shop for a digital pool thermometer, I would be looking for the ones that fall in the “value for money” category.

Always, give priority to the top-rated pool thermometer that not only caters to your needs but also, falls well within your budget.

Also, don’t forget to look for additional accessories that the top-rated thermometer comes with.

Installation Procedure

Some swimming pool thermometers come with installation equipment while others don’t come.

Most of these pool thermometers can be easily installed, but some models might take longer for the installation process to get completed.

Furthermore, some models come with a stand-alone thermometer, and you’ve to buy the receiver separately.

Such a swimming pool thermometer gives you the option of combining it with any receiver.

At the same time, there are top-rated floating pool thermometers that come will every necessary thing included and all you need to do is to “set and forget”.

Some thermometers come with multiple receiver options as well.

Nevertheless, you don’t have to get confused with so many options available on the market.

All you need to do is to buy the pool thermometer that not only caters to your needs but also, falls well within your budget.

Another important thing that you must look for when it comes to buying a pool thermometer is the way it is attached to the pool.

Some pool thermometer models hang on the side of your pool or are attached outside of your pool with a probe hanging down.

Other pool thermometers float on the surface of the pool water.

One of the best places for installing the hanging thermometer could be the pool stairs.


Most of the good quality pool thermometers come along with calibration so you don’t have to worry at all about calibration in particular.

But, if you’ve bought a cheap pool thermometer that is not calibrated then for the sake of accurate reading you need to calibrate it as soon as possible.

If you’re not able to calibrate your floating pool thermometer then definitely, you should find a replacement for it.

On the other hand, if your pool thermometer comes with an option of calibration then you should refer to the instruction guide.


Some of the digital pool thermometers come with alarm options.

The purpose of an alarm is to alert you whenever someone tries to enter the pool or when the temperature of the pool water reaches a certain level.

Moreover, if your pool thermometer has an alarm option then you can customize it to send you alerts when the pool water becomes either too cold or too hot.

And, it also helps you to manage the quality of your pool water along with pool chemical chemistry in an efficient way.

I highly recommend you buy a pool thermometer that has a built-in alarm feature if you use the pool for a longer duration on a regular basis.


As promised to my clientele and readers of this blog, I would be responding to the queries related to the best pool thermometer to help you clear your doubts, and thus, make an informed buying decision.

Do I need a pool thermometer?

Definitely, you need a pool thermometer, and there are numerous reasons for it.

As a pool owner or a swimmer, it is important for you to know the exact temperature of your pool water.

Safety must be a top priority for all of us, and you can’t expect the same result from a traditional or regular thermometer that you can achieve from a pool thermometer.

The traditional thermometer has its own share of pros and cons, and the worst being the leakage problem.

Many of the traditional thermometer models can’t withstand the pool chemical and result in leakage.

I’ve personally experienced such problems with the traditional thermometer in the past.

What are the benefits of investing in a pool thermometer?

Definitely, a good question, indeed.

To be honest, there are numerous benefits to investing in a high-quality pool thermometer.

A pool thermometer is definitely more convenient in tracking the water temperature in your pool and the best part is, it sets the exact number.

It also has the benefit of error-free reading and ease of use.

The digital pool thermometers are not only accurate but fast also.

It goes without saying that most digital thermometers update on their own every 30 seconds so you can expect real-time information about your pool temperature.

Trust me, the digital pool thermometers are among the “most accurate thermometers” available on the market.

Even in the case of balancing the pool chemical, knowing the exact number would help you to achieve optimum results in an epigrammatic span of time.

Correct me, if I’m wrong.

Even though you’re having loads and loads of pool toys and other equipment including pool lights floating in your pool, you don’t have to worry at all about the pool thermometers because they are small and compact and will occupy very little space.

Can temperature affect pool water quality?

Definitely, a variation in temperature can impact the pool water quality, so the use of a high-quality pool thermometer becomes very important.

Let’s understand it with an example.

If the temperature of your pool water surges above a certain level then it can aggravate algae and bacteria growth which can turn your pool water either green or cloudy.

In layman’s terms, the warmer your pool water becomes the faster the bacteria would grow.

Many of the newbies wouldn’t be aware of the fact that bacteria love warmth, especially in a warm environment.

As the water starts becoming hotter and hotter, the bacteria will start thriving, and as a result, the free chlorine will start getting eaten up at an alarming rate which will finally lead to an imbalance in the pool chemistry.

Moreover, if you stay in a pool that is very hot for a longer duration then you might get dehydrated.

You can think of something similar to staying in hot tubs for a longer duration.

Another problem that you might face is overheating or muscle cramps.

If the pool water is too hot or too cold then chances are high that it will lead to the damaging of the pool itself.

Do swimming pool thermometers contain mercury?

Well, to be honest, the top-rated pool thermometers don’t contain mercury as the metal isn’t only expensive but also dangerous.

You’ll find many of the pool thermometers containing liquid such as alcohol to help you with the temperature readings.

However, if you’re not using a floating pool thermometer but rather using a thermometer beneath the pool and want to mitigate the risk of its breaking, then a digital pool thermometer could be a better option for you.

Not only does the digital pool thermometer has a number displayed on the screen but also is very resistant to damage.

How can I set up my floating pool digital thermometer?

Well, I’m attaching the self-explanatory video for your perusal.

How can I keep my pool thermometer from getting into the skimmer?

Well, to be honest, most of the top-rated pool thermometers come with a leash that can be attached to the side of your pool.

You can even be creative, and tie your pool thermometer to the chair leg, an inflatable toy, a pool ladder, etc.

Even you could tie a weight at the end of the thermometer leash and drop it over the side of the pool.

What are the dangers of a broken thermometer in a pool?

If your best pool thermometer comprises glass, then definitely, pieces of glass from a broken thermometer are dangerous to not only the swimmers but also pets, and kids that are roaming near the pool.

The glass pieces can create trouble for the people walking alongside the pool or even on the pool floor.

Small pieces of glass can even stick to the swimmers’ hair or clothing and maybe a point of concern later.

Another danger that comes with a broken thermometer is its liquid content.

If the liquid gets spilled out into your pool water then it might lead to various problems including nausea, vomiting, and other health problems.

It’s A Wrap
