How to Buy the Best Digital Pool Water Testers
1. Testing Features
For the most well-balanced pool, you need to focus on a couple of testing features while selecting the best electronic pool tester. Here is a quick cheat sheet to ensure that the chemical levels stay within the suitable range:
- pH Level: 7.2 – 7.6
- Alkalinity: 80 – 120 ppm
- Free Available Chlorine: 1 – 3 ppm
- Calcium Hardness: 180 – 220 ppm
- Bromine: 3 – 5 ppm
- Cyanuric Acid: 30 – 50 ppm
The digital pool water testers are more accurate than other methods. Also, they are easy to read as the water test levels are displayed on the LCD screen.
You need to select a product that gives you maximum testing features. Let’s take a look at each of these features in detail:
Water with a high pH level can cause breathing problems and allergies. It is significant to check the water’s pH level to keep the pool usable and sanitized for swimming. The Alkalinity test also measures the water’s ability to prevent pH fluctuations.

Chlorine water is highly demeaning to the skin. You need to keep the chlorine content in check. It should not be more than 3 ppm. Anything more than that can cause skin irritation and also leaves a pungent smell in the water.
The cyanuric test kit measures the water’s level of conditioners and stabilizers. The component is found in the commercially available chlorine. It is essential to maintain the CYA level of the pool to prevent the destruction of chlorine because of the sunlight.
The hardness test determines if the pool water is hard or soft. If there is a high level of calcium, the pool will have scaling issues, near the heating elements or close to the pool pump. It also harms the eyes of the swimmers.
At the same time, if the water inside the pool is too soft, it will probably corrode the metal installed in the pool. Therefore, you need to check the calcium hardness of water and treat it accordingly.
The La Motte 2056 gives you maximum testing features with highest accuracy.

The whole purpose of buying a digital pool water tester is to get the most accurate results. You need to invest in a machine that helps in evaluating different water cleanliness features with maximum accuracy. It should be able to provide accurate pH level, chlorine, and hardness.
3. Ease of Use
The last thing that any buyer would want is to stress up on the device’s usability. You should always look for a model that is easy to understand and operate.
There are some complex devices out there. However, you can also find some of the easy ones that clearly displays different testing results on the screen within minutes.
If you don’t want the hassle of matching the colors from a chart to understand the accuracy level, then try the AquaChek NP207 as it is the easiest digital pool water tester on the list.
4. Auto Off & Hold Function
Thanks to the innovative digital pool water testers, you can now have the feature of auto-off that prevent battery loss. When the device is not used for 10 minutes, it automatically turns off to conserve batteries.
The hold function freezes the test results for some time for the user to see. The HM Digital TDS-4 is an innovative product with auto-off and hold function.
As we conclude the digital pool water tester review, we would like to give you a rundown on the best-recommended products on the market.
