Perfect for measuring swimming pools, SPA, Hot Tub Water, aquariums, fish tank water, hydroponics, drinking water, home wine/beer/juice brewing, well water, koi pond water, RO system, aquaculture, etc.. And it can be used for a long time, relatively frequent purchase of test paper or test reagent, can save your money. Accurate H2 Water Tester: The H2 tester provides two test modes (ppb/ppm), ensuring it meets your needs whether you prefer ppb or ppm mode. Switching between ppb and ppm modes is effortless with a quick press of the MODE/CAL button. No need for complicated color contrasts. Say goodbye to hydrogen test drops and test strips. 3-Point Calibration: The pH meter utilizes a high sensitivity glass probe that measures from 0.00 to 14.00 pH with a resolution of 0.01 pH. Our pH meters utilize a meticulous three-point (4.00, 6.86, and 9.18) calibration to ensure accurate measurements. For your convenience, the pH tester is pre-calibrated and comes with pH calibration powder, so there is no need to purchase additional calibration solutions to use it right out of the box. The pH and ORP testers are available for all your hydrogen water testing needs. Automatic Temperature Compensation: Our digital pH meter is equipped with automatic temperature compensation, ensuring highly accurate readings despite temperature variations. Unlike conventional pH meters limited to a range of 0°C to 50°C, ours offers a broader operating range from 0°C to 60°C (32°F to 140°F). This extended range effectively minimizes potential errors caused by fluctuating liquid temperatures, thereby enhancing the precision of pH measurements. Automatic Power-Off Function and Backlit Display: Our pH meter includes an automatic power-off feature, which conserves power by turning it off after 5 minutes of inactivity. Additionally, the pH meter is equipped with a green backlit LCD, ensuring that measurement results are clearly visible in all conditions. Pocket size design to help you measure solution anytime and anywhere. ppm Tester Specifications: pH Range: 0.01～14.00pH Resolution: 0.01pH Accuracy: ±0.005pH ORP Range: ±999mV Resolution: 1mV Accuracy: ±2mV H2 Range: 0-2400ppb; 0.001-2.400 Resolution: 2ppb; 2ppm Accuracy: ±10ppb; ±10ppm Temperature Range: 0.1-60.0℃ 32.0-140℉ Resolution: 1℃/℉ Accuracy: ±0.5 Operation Environment: 0-60℃(32.0-140℉); RH100% Waterproof Level: IP67 Battery: 3 * 1.5V(LR44) not include Screen Size: 33 * 24mm Size Weight: 183 * 37 * 37mm(7.2 * 1.5 * 1.5in) Display: LCD digital display Backlight: Yes Temperature: Automatic Temperature Compensation 0-60℃ HOLD: Data lock Automatic Shut-off: 5minutes Attention: Clean the electrode after using PH calibration: One point or two points or three points automatically. If the meter can't identify the solution, change the electrode, or contact us. Only through electrolysis, the hydrogen in the water will be released to form H2, so tap water or drinking water can not be directly measured to PPM or PPB, please electrolyze the water and then measure it, or measure the water in the hydrogen-rich cup. The hydrogen water ideal pH is 6.5~8.5 and the ORP is -150 ~-850mV. How to Calibrate the pH ? 1. Before calibration, prepare 3 beakers containing separately 250ml of pH 4.00/pH 6.86/pH 9.18 standard solution. 2. Rinse the electrode with clean distilled water and wipe it dry. Turn on the pH meter and adjust to pH mode. 3. Immerse the electrode into the pH6.86 buffer solution, wait for the value to stabilize, press "CAL" for 5s, and the screen will display "CAL", when pH6.86 flashes 3 times, the calibration of pH6.86 is finished. 4. Repeat the above steps to calibrate pH4.00 or pH9.18. FQA Q: What type of battery does the product use? Are batteries shipped?
