general function description:

Min/Max value memory:
highest and lowest value measured are saved

auto-hold:
recognizes automatically a constant measuring value and freezes it

auto power off:
device is automatically switched off after a selected period
if unused (0 to 120 min., or deactivated)

additional display for
pH-electrode and battery:
bar graph display

 

low battery display:
"BAT"
 

automatic temperature
compensation:
There is an automatic temperature compensation (ATC) within
the range of 0°C to +105°C for operation mode "pH" and if
a temperature probe is connected.
Without connected probe the temperature can be input manually.
 

pH-calibration:
The used buffer is detected automatically.
The temperature probe dependency of the buffer is automatically
compensated.

permissible electrode data:

asymmetry:
+55 mV / slope: 45 to 62 mV / pH

The condition of pH-electrode is checked at each calibration.
1-, 2- or 3-point calibration with characteristics bend for
GREISINGER-standard-buffer, buffer to DIN 19266 or manual
buffer input.
 

redox-measurement (ORP):
2 possibilities:

"mV"
standard-redox- or mV-measurement

"mVH"
conversion to hydrogen systems according to
DIN38404 part 6
 

rH-measurement:
The rH-value is calculated from a redox-value measured and
a pH-value manually input .
