TrolMaster Heavy-Duty Inline Nutrient EC/Temp Sensor (PCT-3)

Next-Generation Inline EC & Temperature Probe for Hydroponics, Irrigation & Environmental Control Systems

The TrolMaster PCT-3 Heavy-Duty Inline Nutrient EC/Temperature Sensor is an upgraded, high-precision probe engineered for reliable electrical conductivity (EC) and temperature monitoring in nutrient solutions. Designed for modern hydroponic, aquaponic, and fertigation systems, the PCT-3 offers enhanced stability, improved durability, and easier integration compared to previous models.

The redesigned reduced-diameter protective sleeve and threaded body allow the PCT-3 to be installed directly into standard 3/4-inch PVC tee fittings, enabling seamless inline measurement within irrigation plumbing. With a shorter probe length and enhanced sensor element, the PCT-3 provides more accurate readings even in tight spaces or compact reservoir setups.

Fully compatible with TrolMaster environmental platforms through AMP-2 and AMP-3 sensor boards, the PCT-3 integrates effortlessly into Aqua-X, Aqua-X Pro/Plus, Green-X, and Tent-X systems—powering advanced automation for nutrient management, environmental control, and crop optimization.
