What You Should Know About the Thermometers
As a swimming pool owner, there are a lot of aspects that you need to take into consideration when ensuring that the water is safe to swim in. One of the main elements is the temperature of the pool water, as you have to make sure that it is not too high, moment when you will sweat and feel uncomfortable when swimming in it, but that it is not too low either as you might catch a cold due to the low temperature of the water.
This is where the digital pool thermometer comes in handy as it allows you to keep a constant eye on the temperature of the water, thus getting the chance to be aware of when it is truly safe to enter the pool.

While it is true that this device is a must-have for all pool owners due to the safety element that it adds to the swimming experience, it is especially great to have for those who have small children.

Thus, make a small effort and invest in the thermometer to ensure everyone’s well-being.
Why You Need a Thermometer for the Pool
Although pool thermometers usually are not big investments, some people are still not receptive to the idea of investing in them, which is a shame considering how much you could benefit from owning one. If you are one of the pool owners who still does not have a thermometer, read the following lines to find out what are the advantages of owning it, and you will surely understand why it is a necessity.
- Digital thermometers are extremely easy to use, this being a major advantage especially for those who are not tech savvy and who tend to be overwhelmed by intricate devices. The display of these thermometers is easy to read, meaning that you won’t have a hard time figuring out what the temperature is. Also, as you have already noticed, most of the models in our top come with receptors that allow you to check the temperature of the pool’s water without leaving the house.
- Another aspect that makes owning it necessary is the fact that it delivers fast and accurate results. By using it, you will be constantly aware of the precise temperature of the water, so you won’t get in it until it is perfect and safe to swim in. This comes in handy especially for those who have small children, the kids not being safe if they swim in cold water, being in danger of catching colds.

What to Look for When You Go Shopping
Although swimming pool thermometers are small and easy to use, this does not mean that finding a great performing model is an easy task. On the contrary, with so many digital thermometers on the market, sticking to a certain model becomes hard as you get overwhelmed by the variety of products. To make your search easier, we will show you in the following lines what you must look for when you go shopping in order to make a smart investment.
Line of Sight
How It Is Powered
What Is Included in the Package
The line of sight indicates how far the device can wirelessly transmit the data that is gathering regarding the pool’s temperature. When you buy a digital thermometer that works with a transmitter, it is crucial to pay attention to this spec as it shows how far away from the thermometer you can keep the transmitter. The top tier pool thermometers on the market offer a generous line of sight of at least 300 feet, thus allowing you to place the transmitter in the house and check the pool’s temperature without stepping outside.
As you have already noticed if you paid attention to the comparison table above, these devices are either exclusively battery powered or they are solar powered and they have a battery backup. Undoubtedly, the solar-powered models are a more Eco-friendly choice to go with, and we recommend that you invest in them.
Some thermometers come on their own, while others come with a transmitter onto which the data gathered by the digital thermometer is transmitted to offer you a more convenient manner of finding out how cold or warm the pool water is. Obviously, it is a better deal to invest in a model that comes with both a receiver and a transmitter because the price difference is not that big and you will have a more easy-to-use device as well.
The warranty that backs up a pool thermometer not only shows for how long the manufacturer is willing to repair or replace the product free of charge, but it shows how much the manufacturer trusts the device as well. Thus, a 1-year warranty like the one offered for the Ambient Weather WS-14 shows that this is a high-end thermometer that was made with durable materials and attention was paid to every detail when manufacturing it. We recommend that you not neglect this aspect if you want to make sure that the digital thermometer you invest in is actually of a superior quality.
Useful Troubleshooting Guide
Pool thermometers, just like all other digital products, can be faced with functionality issues. A troubleshooting guide comes in handy as there are common malfunctions that usually occur, and the fixes to these issues are generally easy. To put it in better words, you will likely be able to resolve certain problems without having to call the customer support department and ask for guidance or call in a professional to repair the product.
|Problem||How to Fix It|
