HACH LANGE
Transmitters
Water analysis and fluid treatment transmitters provide continuous measurement, display and transmission of physico-chemical parameters in industrial processes and treatment plants.
Capable of handling pH, conductivity, dissolved oxygen, turbidity or chlorine measurements via digital or analog sensors, as with the Hach Lange sc200 universal controller, they centralise analysis data on a clear display and send the signals to your automation systems.
Discover our range of refurbished analysis transmitters, process controllers and communication modules to maintain rigorous quality control of your effluents and process fluids.

FAQ
A universal transmitter is designed to accept a wide variety of sensors (pH, ORP, turbidity, oxygen, conductivity) in single- or multi-parameter configurations. It converts the raw signals from the measuring probes into usable digital data, manages calibration cycles and transmits the values to control systems via 4-20 mA outputs or fieldbuses (PROFIBUS, Modbus).
A failure usually shows up as a recurring calibration error message, aberrant or frozen readings, loss of the 4-20 mA output signal to the PLC, an illegible or blank LCD screen, or inability to communicate with the connected sensor (sensor communication fault).
Yes, transmitters installed in humid or corrosive environments often suffer failures in the power supply, sensor connectors or housing seals. A workshop overhaul replaces faulty electronic boards, restores the IP65/IP67 sealing and checks the analog/digital acquisition stages.
Every transmitter is put on a complete powered test bench: power supply check, connection to reference sensors, accuracy check of the measurement chain, validation of alarm relay switching and linearity test of the 4-20 mA analog outputs.
