It's difficult to know the pH value and the chlorine level just by looking at the colour of the test paper after taking out from a swimming pool or a spa as the colour cannot be identified just by human's eyes easily. That's why we recommend this innovative design for this purpose. Safety measure range for Chlorine level is from 1.2 to 1.7 ppm and the safety measure range for pH level is from 7.2 to 7.8.

Description:

1. Large screen showing the testing result on both PH and Chlorine level.
2. Easy to use and have result instantly and accurately.
3. Light weight and easy to carry.
4. No chemical agent need.
5. Easy maintenance.
