PS-202: Dual Display TDS Controller

A close-up of the detachable sensor

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

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.
• 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).
