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) (part #SP-1-PSC).
- Protective cover also available (sold separately)
EC Range: 0-9999 µS
TDS Range: 0 - 5000 ppm
Temperature Range: 1-75°C; 33-167 °F
Accuracy: ±2% (of the reading)
Conversion Factor: NaCl (avg. 0.5)
Resolution: 0.1 µS/ppm (0-999); 1 µS/ppm (1000-9999)
