further functions GMH 3531:
automatic temperature compensation:
In operation mode „pH“
and with connected temperature probe an automatic temperature
compensation (ATC) is possible in the range 0°C to +105°C. Without
temperature probe a manual input of the temperature is possible.
pH calibration:
Buffer detection, temperature compensation and sensor rating according to calibration result (from 10 % to 100 %) is done automatically.
1-, 2- or 3- point calibration with standard buffer, buffer according to DIN19266 (A, C, D, F, G) or manual buffer selection.

1-, 2- or 3- point calibration with standard buffer, buffer according to DIN19266 (A, C, D, F, G) or manual buffer selection.
calibration interval:
The device asks for a recalibration after a selectable time period (1 to 365 days or inactive).

redox measurement (ORP):
There are two choices:
There are two choices:
„mV“: standard redox or mV measurement
„mVH“:
temp. compensated conversion to hydrogen system acc. to DIN38404 part
6, table 1 based on the standard redox electrode (e.g. GE 105 with Ag /
AgCl system and 3 mol KCl).
rH measurement:
Calculation of the rH value by means of a redox measurement and by manual entering of the pH-value. The pH-value may also be taken from a previous pH measurement.
