Calibration and measurement
‣
Remove the protection cap for calibration and measurement.
‣
pH/ORP sensors which are stored dry must be immersed in medium for at least 24 hours
before use. Otherwise severe value drifting can be expected.
‣
If the protection cap is no longer used to store the sensor, store the sensor in a KCl solution
(3 mol/l) or buffer solution (pH 7.00).
‣
The frequency at which a sensor calibration or sensor inspection is performed depends on
the operating conditions (fouling, chemical load).
‣
Two-point calibration is required for pH sensors. Use quality buffer from Endress+Hauser,
e.g. CPY20.
pH or ORP sensors with Memosens technology do not need to be calibrated when they
are connected for the first time. Calibration is only required if very strict accuracy
requirements must be met or if the sensor has been in storage for longer than three
months.
pH and ORP:
1.
Immerse the sensor into a defined buffer solution (e.g. pH 7 or 220 mV).
2.
Perform the calibration at the measuring device:
