The M420 transmitter series stands for reliability in loop-powered applications. When your process requires the highest safety level for pH, oxygen and conductivity measurement, the M420 brings you the best performance and the advantages of the state-of-the-art ISM technology* for efficient maintenance.
Outstanding Reliability and Safety
The M400 2-wire provides outstanding reliability and process safety thanks to advanced ISM functionality and its rugged aluminum die cast housing.
Designed for Versatility
This transmitter accepts a pH, ORP, Conductivity, DO and dissolved CO2 sensors, and both analog or digital ISM sensors giving flexibility in use.
Easy System Integration
The HART interface allows easy system integration and offers remote access to the transmitter and sensor diagnostics
