E H glass electrode is not soaked in water. Why can't it be used?

often many customers due to on-site reasons, after the PH glass electrode is installed, the water level drops or stops production for a period of time, causing the glass electrode to be exposed in the air and dry up for a long time, and then the instrument reports an error or the value is not allowed when it is used again.

is mainly that the ion activity of this glass electrode diaphragm decreases in a long-term dry environment, and then the impedance increases, so that the output current becomes extremely small.

usually use glass electrode measurement and calibration must pay attention to the following:
