Water Quality Tester, Electronic pH Meter, Portable Chlorine Meter, High-Precision pH Meter for Drinking Water, Hydroponics, Aquariums, and Drinking Water

Water Quality Tester pH/Cl2 -- This water quality tester is designed to test the pH and chlorine levels in swimming pools and spas. A large display quickly shows the test result with high accuracy. Lightweight and compact, easy to carry. Tip: When measuring chlorine, you must use a 1.5 PPM Cl standard solution, which is not included. Measuring Range -- The large display shows the pH and chlorine level test results for easy and accurate readings. Chlorine level within the safe measuring range: 1.2-1.7 ppm. pH level within the safe measuring range: 7.2-7.8. Application -- This tester is intended for testing water pH and chlorine levels in swimming pools, saunas, aquariums, and spas. Ideal for home drinking water, ponds, etc. Material -- This tester is made of a premium plastic casing, durable and sturdy. Battery: 1 x 1.5V "AA" alkaline battery (not included). Storage Instructions - 1. When not in use, please turn the knob to the off position (in the pH direction until it can no longer be moved). 2. Store in a cool, dry place and avoid direct sunlight. 3. Do not immerse the test stem in any liquid other than pool water and hot spring water. 4. Regularly check the pH level. Material: Plastic + Metal. Size: approx. 7.1" x 4.6" x 1.2" Power Source: 1 x 1.5V AA battery (not included) Package Weight: 220g Instructions: 1. pH Measurement (without battery): Measuring Neutral Value / Acidity Value / Alkalinity Value: First, turn the knob to pH until it clicks into place. Gently wipe the metal rod with fine sandpaper to remove limescale, rinse the test rod with clean water, then wipe with a paper towel or clean cloth, etc., for 3 to 5 seconds to eliminate static electricity and begin the measurement. (1) Insert the test rod into the neutral solution at the black position. (2) The pointer will move slowly, and the reading will be taken once the pointer stops oscillating (approximately 3 to 5 minutes). 2. Chlorine Value Measurement (requires installation of a Battery): 1. Finding the Adjustment Point A. Install a 1.5V AA alkaline battery. Turn the knob towards CL until it can no longer be moved. C. Insert the clear metal rod into the water in the black position (the water should be a standard solution with a CL value of 1.5 PPM). D. Gently stir the water with the metal rod, then slowly adjust the knob to the right until the pointer indicates a known standard CL value. E. Remove the test rod from the water. Be careful not to move the knob. The pointer will move to the right and stop with a letter between A and E. This letter is the adjustment point. 2. The Measurement: A. Set the pointer to the "adjustment point" position. B. Insert the cleaned metal rod into the water in the black position. The pointer will move slowly and wait for the hand to stop reading before taking a reading (approximately 3 to 5 minutes). Sold by the cool grid store
