New controller includes extended range, digital calibration, on-screen temperature, tri-color display and 4-20mA output.
* Monitors and controls TDS/EC levels for high output commercial systems.
* Large, bright L.E.D. display.
* 4-20mA output signal can connect to a PLC to record values.
* An alarm will sound if the TDS /EC level rises above the user-set level.
* A switch will control a device based upon the set point.
* On-screen temperature display (C/F).
* Installs easily in minutes.
* Includes one sensor probe (at no extra cost).
* Protective cover also available (sold separately)
