The calibration process is designed for use with Hamilton calibration solutions (500 ml con-
tainer). Although it is possible to use other calibration solutions, SIGRIST-PHOTOMETER ex-
pressly recommends using the Hamilton standards.  
 
The pH sensor is subject to two-point calibration. All other sensors are subject to single-point 
calibration. 
The oxygen sensor is calibrated against ambient air. As experience shows, the oxygen sensor 
needs some time for a stable measurement of the ambient air. Preferably, it should be the 
first sensor to be removed from the measuring cell block, cleaned and dried, and then only 
be calibrated at the end. 
 
 

8.1.1.2

 

Measurements with temperature dependency 

Many measurements are extremely dependent on the temperature. This dependency is cor-
rected automatically by the sensors. Nonetheless, the calibration solutions and sensors 
should still have approximately the same temperature as the calibration is only made when 
the measuring value and temperature are stable.
