- Can be changed over from pH to mV / ORP (Redox voltage)
- Simple connection of the sensors with screw terminals
- Asymmetric and symmetric connection of the pH-sensors
- 2 galvanically isolated analog outputs 0(4) ... 20mA / 0(2) ... 10V freely
configurable as actual value output for pH, Redox or temperature - Switching output: SPDT relay (changeover contact)
- Monitoring of the medium temperature is possible
- Simple, guided calibration procedure
- 3-way isolation (input, output and supply voltage are galvanically isolated from one another)
- For mounting on a DIN rail
- Calibration timer
- Delivery including calibration certificate
Depending on the configuration, the instrument measures and regulates the pH-value or the Redox voltage in aqueous solutions. Typical applications are in general water and wastewater management, measurement of drinking water, process water, surface water and sea water, swimming pool and well water, aquariums, etc.
The transmitter has two analog inputs. The primary analog input is for connection of a pH or Redox electrode. PH or Redox sensors with an isolated reference electrode can also be connected, as well as antimony electrodes. The second analog input is for connection of an RTD temperature probe Pt100 or Pt1000 for temperature compensation.
There are up to two analog outputs and a SPDT relay (changeover contact) available. The analog outputs are galvanically isolated and assigned to the inputs. Either the primary value (pHvalue or Redox voltage) or the temperature can be assigned to the relay contact.
The devices can be operated and configured using the front face buttons and the integrated LCD, or the configuration can also be done very conveniently from a computer using the optional cable and setup program. It is possible to save and print the configuration data from the setup program, thus simplifying plant documentation and allowing for easy downloading of the configuration file to multiple units.
The devices are supplied with a calibration certificate in which the device data and calibration data are documented.
