Buying Guide for Digital & Electronic Pool Tester

It is very important to have a basic knowledge of digital testers for pools. This will help you to select the best pool tester for you. Since the requirement and expectations of each individual are different, we will share some important things you must look for in the best device. Based on these devices, you can select a digital pool tester easily.

Electric Pool Tester Accuracy

Suppose, you got yourself an inaccurate digital tester. Will there be any difference? Of course, there will be. The main purpose of doing any test is to provide you with proper data about your pool. If the data is not accurate, then, you may add chemicals that could damage your pool. Let us say that the readings by the inaccurate device showed that the Ph level is 8. However, in reality, the PH is 7.55, which is the normal Ph for water. Hence, you will end up taking measures to reduce the PH, which is not required.

Thus, it is recommended to select the devices that are reputed for their accuracy. In the case of digital testers, accuracy indeed decreases with the number of tests a device can conduct. Therefore, select a device that can conduct a specific water test like the salt test or free chlorine test.

Digital Pool Tester Frequently Asked Questions

Here are some of the most commonly asked questions related to digital pool testers.

How accurate are home water testing kits? What is the most accurate kit?

The answer to this question depends on the type of test kit you have bought. As discussed earlier, there are two types of test kits: manual and digital. Though both are highly accurate, their accuracy changes in some scenarios. If you are looking for a kit that can perform more than five types of water tests, then the manual is the right one. These kits offer different equipment, chemicals, and test tubes to conduct a test. They are solely dependent on the basic principle of chemistry. Hence, they give precise test readings.

However, if you are looking for a test kit that can perform a specific test accurately, then, digital kits are great. Digital test kits are a living example of technology. They offer LCDs, which project accurate readings. They also consist of superfast microprocessors that give you the results within a few seconds. The most accurate digital test kit is the HM digital kit.

Therefore, the accuracy of a tester depends on your requirements. Choose wisely, and you will surely find the most accurate kit.

Are pool testing strips accurate?

It depends on your knowledge of water test strips. Water testing strips are the most basic version of finding out Ph, alkalinity, and many more results. Let us say that you have an in-depth knowledge of these strips; then, they are extremely accurate compared to all kits on the market.

The biggest problem with water testing strips is that they are difficult to use. They have a complex procedure, unlike digital testing kits. You have to soak the strip for more than 15 minutes in water. After that, you have to assess the color of it with the color chart. Many people face difficulty in the judgment of the correct color. There are many instances where people ended up with the wrong result.

For how long can I use a pool testing kit?

There is a huge difference in the durability of both manuals as well as digital pool testing kits. Manual pool testing kits barely last as long as a season. There are chances that you might have to buy two kits within a season.

On the other hand, digital pool testing kits last much longer. If maintained properly, a digital kit can last for more than 3 years. Hence, they are a great deal for the long run.

Can rainwater affect the Ph of pool water?

It is generally believed that a change in Ph due to rain is negligible. However, this is not true. Rain can change the Ph of your pool by a huge margin. Usually, rainwater is slightly acidic, thanks to the pollution created by us. Hence, rainwater decreases the Ph value of pool water too.

This can cause skin irritation and other skin diseases if the water is not treated properly. Therefore, it is best to check the Ph value of your pool with a pool testing kit and treat it.

Digital Pool Tester Conclusion
