The Mettler Toledo M400 2XH Type 2 (2-Wire) is a one-channel analytical transmitter designed for intrinsically safe, two-wire process measurement installations.
It accommodates analog and digital sensors for pH/ORP, pH/pNa, 2-electrode and 4-electrode conductivity, amperometric and optical dissolved oxygen, and dissolved CO2 measurement.
HART communication supports connection with compatible process control and asset management systems.
Integrated PID control and two open-collector digital outputs provide additional capabilities for measurement and control applications.
