The measuring and switching device for DIN rail mounting measures and controls, depending on the configuration, the pH value or the redox voltage in aqueous solutions. Typical areas of application are general water and wastewater management, the measurement of drinking and wastewater, process water, surface and sea water, swimming pool and well water, professional aquariums, etc. The measuring transducer has two analog inputs. The first analog input (main input for pH value or redox voltage) is intended for the connection of single-rod measuring chains or electrodes with a separate reference electrode. The device is also prepared for the connection of antimony electrodes. A Pt100 or Pt1000 resistance thermometer can be connected to the second analog input. An analog output is available. The devices are operated and configured using buttons and the integrated LC display. Alternatively, this can also be done very conveniently via the setup connection (notebook / PC) with the optional setup program. The setup program also makes it possible to print out the configuration data. This makes system documentation easier. The devices are delivered with a calibration certificate in which the device and adjustment data are documented. The voltage is supplied via a DC 20..30 V power pack.
