pH and Redox

5.1. Basic Rules for pH and Redox

Calibration

interval

To ensure correct measurement, calibrate pH and redox sensors 

monthly. The calibration procedure is described in 

Calibration of pH 

and Redox Sensors, p. 29

.

Storage of pH

and redox

sensors

After use, rinse the pH or redox sensor with clean water. To prevent 

the sensor from drying out, fill the protection cap with clean water. 

Then slide the knurled nut [C] onto the sensor shaft, push the sen

-

sor shaft into the protection cap as far as it will go and screw the 

knurled nut [C] tightly to seal it.

NOTICE: 

The rubber cap [E] that the sensor is delivered with is 

not intended for daily use and can be disposed of.
