Product Details: This digital water tester provides a simple, chemical-free solution for monitoring pool and spa water quality. Its intuitive design allows for quick testing with high accuracy, while the compact form makes it easy to carry and store. The tester includes a large, clear screen for instant readings and is built with robust materials to withstand regular use. Ideal for maintaining recommended pH (7.2–7.8) and chlorine (1.2–1.7 ppm) levels, it helps ensure a clean, safe swimming environment. Specifications: - Material: Plastic & Metal - Color: Grey & White - Dimensions: 18 x 11.6 x 3.1 cm / 7.1" x 4.6" x 1.2" - Recommended Levels: - Chlorine: 1.2–1.7 ppm - pH: 7.2–7.8 - Package Weight: 220g - Included: 1 x Water Quality Tester Usage Notes: - Use only in pool or spa water; do not immerse probes in other liquids. - Turn the switch to "OFF" when not in use. - Store in a cool, dry place. How to Use: 1. Initial Calibration (Chlorine): - Test water with a conventional liquid test kit and record the chlorine level. - Insert a 1.5V AA battery into the tester. - Fully immerse the cleaned probes into the water up to the black strip. - Turn the front wheel fully left (CL direction), then slowly rotate right until the needle aligns with your recorded chlorine value (e.g., 1.5 ppm). - Remove probes without touching the wheel; note the letter (A–E) indicated by the needle as your adjustment point. 2. Chlorine Testing: - Set the needle to your adjustment point. - Immerse probes fully into water and wait for the needle to stabilize for an accurate reading. 3. pH Testing: - With probes still in water, turn the wheel fully to "pH" until a click is heard (battery must be on). - Wait for the needle to stabilize and read the pH value. - After use, dry probes gently and store in the side handle. Maintain your pool or spa with confidence using this efficient, easy-to-use digital water tester.
