PS-202 Dual TDS Controller

The PS-202 allows for continuous and simultaneous monitoring and control of TDS levels on two water lines.

•Simultaneously monitors and controls the TDS levels of two water lines (e.g., the feed water and product water) for high output commercial systems.

•Large, bright L.E.D. displays.

•An alarm will sound if the TDS level rises above the user-set level for both lines.

•Installs easily in minutes.

•Includes two 1/2″ sensor probes (at no extra cost).

Range: 0 – 999ppm 

Accuracy: ±2% 

Conversion Factor: NaCl (avg. 0.5)

Resolution: 1 PPM 

ATC: Yes (1 – 65 degrees Celsius) 

Calibration: Adjustable 

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 the output water (line 2) or input water (line 1) reaches or exceeds its control setting (simple switch). The PS-202 can be used to control one or two pumps, solenoid valves or other device.
