PSC-154 TDS/EC Controller with 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)
