Commercial-Grade EC & Temperature Monitoring for Precision Irrigation
The TrolMaster PCT-2 Heavy-Duty EC & Temperature Sensor delivers continuous, high-accuracy monitoring of your nutrient solution, helping growers maintain the ideal conditions for healthy root development and maximum nutrient uptake. Designed for demanding commercial environments, the PCT-2 measures both electrical conductivity (EC) and water temperature, giving you the real-time data needed to optimise irrigation, reduce nutrient waste and produce consistently healthier crops. It connects to compatible Aqua-X, Aqua-X Pro, Aqua-X Plus, Green-X and Tent-X systems via an AMP-2 or AMP-3 Sensor Board.
Built with a heavy-duty commercial probe and a 3.6-metre cable, the PCT-2 offers flexible installation in nutrient reservoirs and is suitable for hydroponics, commercial greenhouses and professional irrigation systems. By continuously monitoring EC and water temperature, growers can quickly identify changes in nutrient concentration before they impact plant health, helping to improve crop consistency and maximise yields.
Frequently Asked Questions
What does the TrolMaster PCT-2 measure?
The PCT-2 continuously measures electrical conductivity (EC) and water temperature, helping growers monitor nutrient strength and irrigation conditions in real time.
What's the difference between the PCT-1 and PCT-2?
The PCT-2 is a heavy-duty commercial-grade EC and temperature sensor designed for more demanding applications and long-term reliability, while the PCT-1 is the standard reservoir sensor.
Which TrolMaster systems is the PCT-2 compatible with?
The PCT-2 is compatible with:
Aqua-X (NFS-1)
Aqua-X Pro (NFS-2)
Aqua-X Plus (NFS-3)
Green-X (GCS-1)
Tent-X (TCS-1)
using the appropriate AMP-2 or AMP-3 Sensor Board.
Do I need a Sensor Board?
Yes. The PCT-2 connects through an AMP-2 or AMP-3 Sensor Board, depending on your controller. It cannot be connected directly to the controller.
Why is monitoring EC and water temperature important?
Maintaining the correct EC ensures plants receive the right nutrient concentration, while stable water temperatures support healthy root development, oxygen availability and efficient nutrient uptake. Together they help prevent nutrient deficiencies, overfeeding and unnecessary crop stress.
Where can the PCT-2 be installed?
The PCT-2 is designed primarily for use in nutrient reservoirs but is also suitable for hydroponic systems, aquariums, laboratories and other water-monitoring applications.
How long is the sensor cable?
The PCT-2 includes a 3.6-metre cable, allowing flexible installation within larger nutrient tanks and irrigation systems.
Who is the PCT-2 designed for?
The PCT-2 is ideal for commercial growers, hydroponic farms, greenhouse operators and serious hobby growers who require reliable EC and temperature monitoring as part of a fully automated irrigation system.
