6 min readMar 1, 2021

It is important for your pool to have the right chemistry.

However, it is impractical to remove the water and add a new batch every time someone goes swimming. Luckily, you can use a pool kit to test properties like acidity and impurities, which can increase the level of infection in your pool and make it unsafe to swim.

However, there are so many models of electronic pool water testers out there, and finding the right one for your needs can be overwhelming. In this article, we will review some of the best pool water testers on the market and highlight their pros and cons. We have also included a buying guide to help purchase the best electronic pool water tester for your needs.

How to Choose the Best Electronic Water Testers

In order to help you decide which electronic pool water tester suit your needs, you need to consider the following factors:

The more tests that a device can do, the better it is. However, this can be always true in Olympic size pools or more. For smaller pools, having devices that can test more than the acidity and other impurities are a bit exaggerated. Those can probably cost you more.

Accurate results are always expected on electronic testers. But as time passes by, it will begin to decrease. By that time, you will need calibration.

If you want to select a water tester, choose the ones that are more accurate. Consider also those that requires less time for calibration.

Almost all electronic water testers have a digital display. They have a small LCD or LED screen on the device.

However, the recent testers are designed with ‘smart technology’. These types of devices can connect with a smart phone or tablet and can notify you through an app.
