further functions:
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.
2-point calibration with buffer capsules (GPH 4, 7, 10).
Buffer detection, temperature compensation and sensor rating according to calibration result (from 10 % to 100 %) is done automatically.
2-point calibration with buffer capsules (GPH 4, 7, 10).
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).
analog output:
0 V to 1 V, not changeable 0 V to 1 V ≙ 0 pH to 14 pH or -2,000 mV to +2,000 mV, connection via 3-pole jack socket Ø 3.5 mm, resolution 13 bit, accuracy 0.05 % at nominal temperature.
