Temperature compensation---The PH meter has an automatic temperature compensation function to adjust the water temperature and quickly test PH readings.

Convenient and practical---turn on the switch, put the probe into the water and stir (make the small glass ball completely contact the liquid), wait for the value to stabilize, and then read the value.

Horizontal display --- The test pen is designed with a horizontal display screen, which can read pH value and temperature value at the same time, making your work easier and more convenient.
