YY-400 PH/ORP/H2＆TEM meter
YY-400 / YY-400N is a newly developed high-precision multifunctional water quality tester, which has the function of measuring PH, ORP, hydrogen ion concentration and water temperature. Automatic temperature compensation (0-60℃) measurement data is updated. Accurate, easy to operate, easy to carry, drinking a lot of water rich in hydrogen ions is good for health. It is suitable for PH, ORP, hydrogen ion concentration and temperature testing applications of household and laboratory water, including swimming pools, ponds, beer, kombucha, aquariums, hydroponics, laboratories, food processing, etc.

Note:
1. The electrode should be cleaned after use
2. PH calibration: 1 point or 2 points or 3 points automatically. If the meter cannot recognize the solution, please replace the electrode or contact the supplier.
3. It has been factory calibrated and can be used directly.
4. After completion, clean the electrode with pure water and keep it dry.
5. Stir gently a few times to ensure that there are no bubbles around the electrode.
6. Do not disassemble the meter without permission.
Ph reset
1. Turn off the meter, press HOLD/TEMP and MODE/CAL at the same time, don't release it.
2.Press ON/OFF, then release all buttons, the reset is complete.
