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).

PRODUCT DESCRIPTION:

- EC range: 0-9999 µS

- TDS range: 0 – 5000 ppm

- Temperature range: 1-75°C; 33-167°F

- Accuracy: ±2% (of reading)

- Conversion factor: NaCl (average value 0.5)

- Resolution: 0.1 µS/ppm (0-999); 1 µS/ppm (1000-9999)

- ATC: Yes (1 – 65°C)

- Calibration: Digital via push button

- Setting the control point: One point controlled by the up/down buttons on the screen (any point in the range)

- Relay control: The unit will open or close the contact when the preset ppm/µS level is reached or exceeded (simple switching). It can be used to control a pump, solenoid valve, or other device.

Frequently Asked Questions

What is the 4-20mA output on the PSC-154 used for?

The 4-20mA output allows you to integrate this controller with external monitoring systems, automation equipment, or data loggers, making it ideal for commercial water filtration systems that require remote signal transmission or automated alerts based on TDS/EC levels.

Does the HM Digital PSC-154 work with my existing RO or water filtration system?

Yes, the PSC-154 is designed as a universal TDS/EC controller that works with most commercial high-performance water systems including RO units, provided your system has a compatible probe connection and appropriate electrical outlet for the controller.

How often do I need to calibrate the PSC-154 controller?

The PSC-154 features digital calibration with automatic temperature compensation (ATC), and most users calibrate it every 6-12 months depending on water quality changes and system usage; the on-screen display makes calibration straightforward without special tools.

What's the difference between the 0-9999 µS measurement range on this model compared to other controllers?

The 0-9999 µS range with 0.1 µS/ppm resolution allows the PSC-154 to provide precise TDS/EC readings across a wide spectrum of water conditions, from very pure water (low µS) to moderately concentrated solutions, giving you more accurate control over your filtration system's performance.

Is the PSC-154 durable enough for continuous commercial use?

Yes, the HM Digital PSC-154 is specifically engineered for commercial high-performance systems with a tri-color display, built-in ATC sensor, and robust construction designed to provide long-term reliability in demanding water treatment environments; the ±2% readout accuracy ensures consistent performance over time.
