Best Pool Thermometer Buying Guide

 Etekcity 1022D

Before you buy any device or appliance, it is good to take into consideration all the important features that you require before you make a purchase. Similarly, when buying a pool thermometer, you need to consider the below mentioned features.

Do make sure that each of the items suits your needs perfectly so that you can have a satisfying experience with the product.

So Which Type Of Thermometer Do You Want?

There are two main types of thermometers available for you to choose from; analog and digital. So which one should you opt for?

Well, both analog and digital thermometers are great options. Both happen to be accurate and work great. However, digital thermometers do hold an upper hand in some cases.

 Milliard Floating Pool

Nonetheless, both of these thermometers are great; simply choose one that suits your requirements.

These thermometers are further divided into three different categories;

  • Floating: these sit on the surface of the water. The reading is usually slightly off since it isn’t fully submerged underwater.
  • Hanging: these simply hang into the pool, and can be tied to sides or to the ladder, deep into the water.
  • Handheld: these thermometers are placed into the water for a few minutes till you get a reading. They come in the form of infrared lasers.

Can You Read Easily?

Although you would expect thermometers to have a readable display, this is something that you need to look out for.

Unfortunately, many times, the display varies a lot from product-to-product.

Usually, thermometers have different display sizes; the brightness or backlight is different, or it may simply not be your preferred display size.

You must also remember that standard analog pool thermometers will be comparatively more difficult to read. You will have to physically go out to the pool just to take a reading.

Is The Reading Accurate Enough?

Regardless of whether you opt for an analog or a digital thermometer, the accuracy can be off by both a small or in some cases, a large amount.

And so you will have to check thoroughly for accuracy.

While the overall quality of the thermometer does affect the readings, you will, however, need to consider other factors as well.

These factors include the reading frequency as well as the number of channels it supports.

From What Distance Will It Work?

The distance that’s between the sensor and the point where you can get a reading of the pool’s temperature is called the “line of sight.”

This line of sight can range from a few meters to hundreds of meters. And so it’s important for you to understand what distance the product is capable of covering, especially if you plan on using it for longer distances.


This, however, is only for wireless thermometers, which are also known as remote pool thermometers.

How Long Will The Battery Last?

If you are using an analog pool thermometer, you don’t have to rely on batteries in order for it to function.

However digital pool thermometers do require batters. Usually, these thermometers require regular household batteries, but in some cases will require solar power instead.

You will have to consider the number of batteries required and how long they last before you need to change them. You will also require a solid battery indicator or alarm as well.

How Long Will The Product Itself Last?

Nobody wants to spend money on a product which lasts only a few months and than needs to be replaced. Durability plays an important part in the choice you make.

Therefore, some things you should consider before buying a pool thermometer that ensures durability include:

Brand name: buy from a well-established and well-known brand to ensure good quality.
