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.

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.
