A perfect buying guide for choosing the right-Best Digital Pool Test Kit

Before deciding your purchase for the best digital pool test kit just ponder over some of the factors below.

Firstly, you should be well-versed with the ideal limits of the chemical levels that should be present in your pool:

  • The pH – 7.2 to 7.6
  • The Alkalinity – 80 to 120 ppm
  • Free Chlorine – 1-3 ppm
  • Bromine – 3-5 ppm
  • Cyanuric Acid – 30 t0 50 ppm
  • The Calcium hardness- 180-220 ppm

These digital testers are capable of providing you with precise readings in an easy way and they are correct as long these are able to read them.

These are very important and the explanation is here under:

If the pool doesn’t possess the correct pH levels then the water becomes acidic and after that the sanitizers are unable to do their work effectively. The ideal range of 7.2-7.6 should be maintained strictly.

When alkalinity test is done it greatly prevents the pH fluctuations.

The best pool test kits come with free Chlorine test. Do you know?  The free Chlorine is the only chemical that acts to keep the pool sanitised. Like the other tests this one is also hold importance for providing maximum sanitisation. Chlorine in excess quantities can cause skin irritations, rashes and make your pool water smell bad.

The CYA (Cyanuric acid) test helps in testing and measuring the conditioners and stabilizers in the pool. This is present in chlorine (commercially available) and is surely a part of any best pool water kit. The disinfecting ability of chlorine is maintained when this element is kept in proper range. Even destruction caused by sunlight can also be minimised by the Cyanuric acid.

Whether your pool water is hard or soft, that is decided by the Calcium hardness test. If the calcium levels are high in your pool then it can cause skin irritation or sore eyes. Softness can make the metal surfaces to corrode. High levels can lead to scale formation inside the pool and pool pump, or on the heating elements.

Convenient to use

If you are a pool owner or home owner then it becomes very convenient to monitor your pool’s health. This also helps you save money and on the other hand it becomes quite important to understand and these digital monitors perfectly and properly. Before you buy, the manual, instructions and reading interpretations should be a part of your kit.

While you test, side-by-side for comparing the results you can let someone else also check your pool water. That will give you a clearer picture of your pool’s condition.

These digital testers are handy, small, light in weight and photometric and serve great for home testing. One should go for a digital reader that is economical, ignores guesswork and displays quick results.
