PSC-154
The HM Digital PSC-154 is a robust and reliable controller designed to maintain TDS/EC levels in high-output commercial systems. With advanced features like extended range, digital calibration, on-screen temperature display, tri-color indicators, and 4-20mA output, it ensures precise monitoring and control.
The built-in sensor with Automatic Temperature Compensation (ATC) guarantees accurate readings across varying temperatures. The bright 5/8″ LED display provides clear and easy-to-read measurements.
Key Features
- Large, Bright LED Display: Clear visibility of TDS/EC and temperature readings.
- 4-20mA Output: Seamless integration with PLCs for data logging.
- Adjustable Alarm: Alerts when TDS/EC levels exceed the user-set threshold.
- Device Control: Operates pumps, solenoid valves, or other devices via relay control.
- On-Screen Temperature Display: Shows readings in both Celsius (°C) and Fahrenheit (°F).
- Digital Calibration: Easy push-button calibration.
- Single Point Set-Point: Adjust settings using simple on-screen up/down buttons.
- Automatic Temperature Compensation (ATC): Maintains accuracy across temperature fluctuations.
- Includes Probe: Comes with the SP-1-PSC sensor probe for reliable operation.
