M420 Transmitter Series - Discontinued Product
For hazardous area applications
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.
Discontinued since: Dec, 2016
For Hazardous Area Applications
Intelligent Sensor Management (ISM), global hazardous area approvals and the rugged design of the M400 2-wire transmitter series provide outstanding operating reliability and process safety. These features ensure the M400`s suitability for use across the chemical industries. Easiest handling and on-site or remote access over HART to advanced ISM predictive diagnostics tools leads to reduced operating costs and increased process uptime.
The M400 2-wire transmitter is a single-channel, multi-parameter unit for pH / ORP, oxygen and conductivity measurement. Thanks to the mixed-mode input, which allows the use of analog or ISM sensors, the M400 2-wire offers a unique and smooth transition from analog to digital technology.
