Measuring range Temperature: -5.0 ... +150.0 °C or 23.0 ... +302.0 °FMeasuring 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-wireSensor 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 indicatorScope of supply: device, battery, manual
Note: w/o accessories, please order pH-probe and calibration accessories (i.e. GAK1400) separately
Applications: • waters, aquaristics, fish farming • drinking water and process monitoring • soil measurements • food production and control • swimming pools • education
