GMH 3531
PH / ORP / TEMPERATURE MEASURING DEVICES- pH / ORP / temperature measuring device
- Measuring range Temperature: -5.0 ... +150.0 °C or 23.0 ... +302.0 °F
- Measuring range pH: 0.00 ... 14.00 pH
- Measuring range redox (ORP): -1999 ... 2000 mV
- Measuring range rH: 0.0 ... 70.0 rH
- Sensor connection temperature: 2 x 4 mm banana socket for Pt1000, 2-wire
- Sensor connection pH/redox: BNC socket
automatic temperature compensation:
In operation mode „pH“ an automatic temperature compensation (ATC) is possible in the range 0 ... 105 °C if a temperature probe is connected. Otherwise a manual input of temperature is possible.
pH calibration:
The buffer type is automatically detected. The temperature dependency of the buffer is automatically compensated.
ORP measurement (redox):
There are 2 choices:
„mV": standard ORP or mV measurement
„mVH": temp. compensated conversion to hydrogen system acc. to DIN38404 part 6, table 1 based on the standard ORP electrode (e.g. GE105 with Ag/AgCl system and 3 mol KCl) used.
rH measurement:
Calculation of the rH value by means of a ORP measurement and by manually entering the pH-value. The pH-value may also be taken from a previous pH measurement.
Functions: Min / max value memory, Hold function, Automatic off function, battery change indicator
Scope of supply: device, battery, manual
Note: w/o accessories, please order pH-probe and calibration accessories (i.e. GAK1400) separately
