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 pH, ORP, Conductivity, DO, and dissolved CO2 sensors as well as 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
Material No.: 30025514
ISM's advanced sensor diagnostics adjust in real time to changes in processing conditions. The HART communication protocol provides for the seamless integration of sensor diagnostics into process control systems.
ISM sensors with Plug and Measure technology can be pre-calibrated in a workshop with iSense software and stored for later use. When connected to the transmitter, calibration data are automatically uploaded and the system is instantly ready to measure.
This multi-parameter transmitter can be used to monitor pH, ORP, conductivity, amperometric dissolved oxygen, optical dissolved oxygen, and dissolved carbon dioxide. One unified interface for a variety of applications simplifies training and use.
