The TrolMaster PCT-3 is a heavy-duty dual-function EC and temperature probe designed for continuous monitoring of nutrient solution in commercial hydroponic and irrigation systems. It can be installed either as a reservoir drop-in sensor or directly inline using a standard 3/4" PVC tee fitting, allowing operators to monitor nutrient conditions at the reservoir, supply manifold, or drain point. Its compact threaded design and 3.6 m cable make it suitable for permanent installation in commercial irrigation runs.

Key Advantage: The PCT-3 combines EC and temperature monitoring in a compact inline/drop-in probe, allowing the same sensor to monitor nutrient solution at different points in an irrigation system. Using one on the supply side and another on the drain side can also provide a before/after EC comparison to identify nutrient drift across the root zone.
