HM Digital PS-203 Dual Display TDS Controller

The PS-203 allows for continuous and simultaneous monitoring and control of TDS levels on two water lines for high-output commercial systems.

Features:

• Simultaneously monitors and controls the TDS levels of two water lines (e.g., the feed water and product water) for high-output commercial systems.
• 4-Digit large, bright L.E.D. displays
• An alarm will sound if the TDS level rises above the user-set level for both lines
• Includes two 1/2″ sensor probes

Specification:

• Range: 0 - 9999ppm
• Accuracy: ±2%
• Conversion Factor: NaCl (avg. 0.5)
• Resolution: 0.1ppm (0-99.9), 1ppm (100-9999)
• ATC: Yes (1-60°C)
• Calibration: Up and Down push button Digital calibration
• Setting: Controlled by on-screen up/down buttons
• Relay Control: The unit will open or close a circuit via dry contacts when the ppm level of either sensor reaches or exceeds the control setting (simple switch). It can be used to control a pump, solenoid valve or other device. Each relay control is independent.
