Overview with pH sensor
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).
