yieryi New 4 in 1 H2/PH/ORP/TEMP Meter H2 hydrogen meter Water Quality Tester for Pools, Drinking Water, Aquariums

FAQ1.Why test some water show zero reading? This pen needs to measured that water containing hydrogen to display reading, We Recommended that the customer electrolyze some hydrogen rich water and will show accurate reading.Feature:

[4-in-1 water quality test] YIERYI PH meter is designed with 4-in-1 function, which can be measured PH, ORP, H2, and Temperature simultaneously with high precision. Omni-directional measurement of water quality to ensure the health of water quality.

[±0.05 pH Accuracy and 3-Point Calibration] With high sensitivity glass probe, YIERYI PH meter’s full measurement range of 0-14pH, 0.01 pH resolution. And pH meter uses a 3-point calibration method, calibrating the electrode to solutions of pH 4.00, pH 6.86, and pH 9.18 to ensure the accuracy of your measurements. [Automatic power-off function & large screen display] The automatic power-off function turns off the power after 5 minutes without any operation to save power. Employs a fully transparent liquid crystal (LCD) to display 4-digit values ​​and the corresponding physical quantity units.

[Waterproof rating IP67] IP67 is an international waterproof and dustproof certification. Protection against dust intrusion, short-time immersion.

[Wide Application] Ideal for household and laboratory pH testing applications, including drinking water, swimming pool, pond, beer brewing, kombucha, aquariums, hydroponics, laboratory, food processing, etc.
