The Mettler Toledo M400 FF Two-Wire (2-Wire) is a multiparameter process transmitter that combines two-wire operation with FOUNDATION Fieldbus communication.
It supports pH, ORP, conductivity, dissolved oxygen, gas-phase oxygen, and dissolved CO₂ measurements using compatible analog or digital ISM sensors.
Designed for integration into compatible process control systems, the transmitter can be applied in hazardous and non-hazardous areas.
Its fieldbus communication capabilities enable analytical measurements and available sensor diagnostic information to be incorporated into the plant control environment.
