The RM4-CO is a very flexible, DIN rail mount instrument for the
measurement and monitoring of conductivity or resistivity. The RM4-CO accepts
input from 1 conductivity cell and 1 temperature compensation sensor. The
instrument is fully programmable from the front pushbuttons and the 2
setpoint relays, included as standard, can be programmed for PI control or
alarm functions. A wide range of power supply and output options are
