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. Recalibration is made at two points (pH 4 and pH 7). - Page 95 Servicing Instruction Manual ScrubberGuard 9.3.1.2 Measurements with temperature dependency Many measurements are extremely dependent on the temperature. This dependency is cor- rected automatically by the sensor.
