Description: Portable Dissolved Hydrogen H2 Meter Digital pH Orp Tester For Driking WaterFeature: [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. Feature 2: Test the PH/ORP/H2 and temperature(℃/℉) of water.Pocket size, lightweight, and portable with backlight & large LCD display for clear and easy reading.PH Reset: 1. Shut-off meter, press HOLD/TEMP, and MODE/CAL simultaneously, don't release. 2. Press ON/OFF, and release all buttons reset is finished.Automatic Temperature Compensation: No longer need to pay attention to the temperature of testing liquid, pH meter can accurately determine the pH value of the sample in the temperature range of 0 °C-60 °C (32 °F-140 °F), so as to solve the inaccurate problem caused by changing the liquid temperature.

Are batteries shipped?A:Generally, products with batteries are not shipped because online logistics cannot transport batteries. The battery type is 3 * 1.5V (LR44) button cell batteries, which can be purchased at local stores. Q: Is it necessary to calibrate the function of the instrument to measure "hydrogen"?A: The product has been calibrated before leaving the factory. The product cannot calibrate the function of the instrument to measure "hydrogen" by itself. Q: Why does the "hydrogen" instrument measuring tap water display "0"? When measuring the "hydrogen" of electrolyzed water, the value will continue to change over time?A: Under normal circumstances, the hydrogen content of water is "0", and the measurement data shows "0", which is correct. Need to use a hydrogen-rich cup after electrolysis, and then measure. The hydrogen content is relatively small, and the measurement data will also display "0". Hydrogen is very easy to volatilize, and the value will continue to decrease over time. Q: What is the unit for measuring hydrogen? How to convert measurement units?A: The factory default measurement unit of the instrument is ppb. When the instrument is turned on, press the FUN" key, and the measurement mode will be switched between ppb and ppm. (1ppm =1000ppb) Q: What should I do if the received product is damaged, cannot be calibrated, cannot work normally, and the meter cannot recognize the solution?A: Please protect the product and contact us in time to report product problems NOTED The hydrogen rich calibration is, in principle, hydrogen rich do not need to be calibrated, but if the customer must calibration just calibration ORP value.As long as the ORP values are calibrated, the hydrogen rich ones are calibrated as well
