Hm Digital Psc-154 Tds/Ec Controller 4-20ma Output Ppm Conductivity Monitor is a 4-20mA TDS/EC controller designed to maintain optimal TDS/EC levels in commercial high-performance systems. It features an extended measuring range, digital calibration, an on-screen temperature display, a tri-color display, and a 4-20mA output.
Built-in sensor for automatic temperature compensation (ATC) guarantees accurate measurements at different temperatures. A bright 5/8" L.E.D. display makes it easy to see the reading measurements.
FEATURES:
- Large and bright LED display.
- 4-20mA output signal can be connected to PLC to record values.
- An alarm will sound if the TDS/EC level exceeds the user set level.
- A given point controls the device switch.
- The screen display shows the temperature (C/F).
- The kit includes one sensor probe (part #SP-1-PSC).
