HM Digital PSC-154 Extended Range EC/TDS Controller with 4-20mA Output

The HM Digital PSC-154 EC/TDS Controller reads in an extended range to monitor and control TDS levels for high output commercial systems. If the TDS level rises above the user-set level, an alarm will sound and the unit will open or close a circuit via dry contacts to control a pump, solenoid valve or other external device. External devices must have their own power supply.
