It features a large screen that displays clearer and faster readings, intuitively reflecting the water quality. The tester is lightweight, small in size, and easy to carry, with holes for convenient hanging. It is designed for durability, made from high-quality thick plastic that is strong and wear-resistant, ensuring long-term use. Technical specifications Power Supply: 1 x 1.5V AA Battery (Not Included) Recommended Chlorine Levels for Pools and Spas: 1.2~1.7 ppm Recommended pH for Pools and Spas: 7.2~7.8 pH Installation Insert one 1.5-volt AA battery into the compartment inside the handle (positive side up). Before first use, calibrate the tester to match your pool or spa water using a conventional liquid test kit. Usage Keep the switch in the OFF position (all the way to "PH") when not in use. Store in a cool, dry place away from sunlight. DO NOT immerse the probe in any liquid other than pool or spa water. Check battery freshness regularly. To find your adjustment point, insert the cleaned metal probes into the water up to the black band and lightly stir the water. Adjust the wheel on the tester to match the chlorine level recorded with the conventional liquid tester.
