Pool Thermometers help you know about the attributes of your swimming pool. 

For example, if it’s too hot, the thermometer will detect if some heating element is corrupted and then enable you to augment expenses without any hassle.

For example, pools with temperature levels between 75F to 85F are suitable for everyone. It also requires minimal supervision as it holds chlorine much longer than a pool warmer than that. 

With pool thermometers, you can check on many other basic parameters such as chlorine and pH levels of the collection to ensure that people using them don’t suffer from chemical burns or any irritation.

What is our research strategy?

When testing and experimenting with several thermometers on the market, we build certain criteria for our research to make specific selections. 

We recommend our readers consider these factors while making any buying decision. We have placed them as follows:

Consistency and Accuracy

The entire purpose of a pool thermometer is to read accurate temperature levels. Accuracy is key here; without that, it would just be a waste of money. 

Unfortunately, there are some minor variations in thermometers since accuracy needs calibration complex in nature.

So, we not only focus on accuracy but also consistency. If you are aware that the thermometer reads at five degrees consistently, you’ll get a true temperature. 

But every time you get a reading, the accuracy varies that might not be useful for you.

Ease of Use

A thermometer, in general, shouldn’t be complex to use. It should involve as minimal effort as it can. 

If a thermometer requires you to continually adjust it, move it, clean it, or other taxing tasks other than simply reading the temperatures, it isn’t very convenient.  

You should ideally look for those that float smoothly (if it’s floatable). If they are digitized, make sure that they don’t have complicated instructions and irrelevant features. 

Also, make sure that the display is clear enough to be read without using any flashlight every time you take it in the pool.


Pool Water thermometers should last long for several seasons. While many pool equipments have a short running span, thermometers go on for years. 

With their simple design, they can survive through heat and other climatic environments associated with the pool.   

Make sure the thermometer you pick doesn’t break down easily and maintains its durability for coming seasons. 

While we recorded that some of them shed color over time, they were still sturdy and durable. The only thing that matters is it remains accurate.

Power Source

Power source doesn’t ring as a huge concern, but it might change your opinion once you start using a thermometer. 

Whether to choose an analog thermometer or a digital one is an important aspect.

Analog thermometers will need minimal maintenance efforts as they don’t have a power source. So you can sip it in the pool and forget about it.  

On the other hand, Digital thermometers need more work. They generally come with batteries or solar power sources. You might change the battery or charge them to keep running, requiring extra effort.  

Batteries have to be changed as they exhaust. This is usually done by some tool, and in some thermometers, you may not get alerts about the battery running low.  

Solar power source requires exposure to the sun to keep the device running. 

Therefore, we recommend finding a thermometer that runs on the least sunlight or contains storage to get a reading even when it is cloudy.
