8.2 Calibration
8.2.1 General information on calibration
Calibration adjusts the raw value measured directly in the test sample to an
independently determined reference value ("lab value"). To determine the refer
-
ence value, a sample is taken from the measuring solution and the relevant
concentration is measured (e.g. photometrically).
A common method is the DPD method for free chlorine. Photometers and test
sets for this can be found in the WTW catalog or on the Internet.
When does calibra
-
tion make sense?
Calibrating can be useful in the following cases:

If the measured values appear to be implausible

Routinely within the framework of the company quality assurance
CAUTION
Contact with the sample can lead to danger to the user!
Depending on the type of sample, suitable protective mea
-
sures must be taken (protective clothing, protective goggles,
etc.).
1. Install the sensor in a flow through armature and provide the sample flow.
or
Submerse the sensor in the sample.
