Jumo Messumformer 202723/8880#00508665

The measuring and switching device for DIN rail mounting measures and regulates, depending on the configuration, the pH value or the redox voltage in aqueous solutions. Typical application areas include general water and wastewater management, the measurement of drinking and wastewater, process water, surface and seawater, swimming pool and well water, as well as professional aquaristics. The measuring transducer has two analog inputs. The first analog input (main input for pH value or redox voltage) is designed for connecting single rod measuring chains or electrodes with a separate reference electrode. The device is also prepared for connecting antimony electrodes. A resistance thermometer Pt100 or Pt1000 can be connected to the second analog input. An analog output is available. The devices are operated and configured via buttons and the integrated LC display. Alternatively, this can also be done very comfortably via the setup connection (laptop/PC) with the optional setup program. The setup program also allows for printing the configuration data, which facilitates system documentation. The devices are delivered with a calibration certificate that documents the device and adjustment data. The power supply is provided via a power supply unit DC 20 to 30 V.
