The conductivity transmitter JUMO ecoTRANS Lf 03 measures the conductivity or the resistance of liquids in conjunction with conductivity measuring cells.
Typical application areas are plants for fresh water monitoring and water treatment, reverse osmosis plants, ion exchanger plants, ultra-pure water and pharmaceutical applications, condensate monitoring, rinsing baths, and cooling water control.
The devices are operated and configured using the keypad and the integrated LCD display. A convenient alternative here is the setup connection (notebook/PC) using the setup program. The setup program also allows printing of the configuration data, which makes plant documentation easier.
The devices come with a calibration certificate in which the device and adjustment data is documented.
