À qui s'adresse cet article ?
- You are adding real-time monitoring because you are tired of manual spot checks and the risk of missing nutrient drift.
- You are integrating EC and temperature data into your controller because you need to catch imbalances before they peak.
Ce que nous avons découvert
- The 3.6 metre cable gives you enough length to position the sensor away from the intake pumps for a true reading.
- The drop-in design makes calibration a quick task since you can easily pull the probe out of the reservoir.
Ce que disent les utilisateurs
- Users who track their reservoir data say they spend less time troubleshooting plant health because the readings are constant.
- Growers who automated their nutrient tracking mention that they stopped guessing at concentrations during rapid growth.
TrolMaster PCT-1 Reservoir EC & Temperature Sensor
Nutrient concentration and water temperature are two of the most actionable data points in any reservoir-based grow — and the TrolMaster PCT-1 puts both under continuous monitoring without manual testing. The PCT-1 connects directly to the AMP-2 sensor board via Mini DIN terminal, feeding live EC and temperature readings into your TrolMaster controller so you can track drift and respond before it affects plant health. Its 3.6-meter cable provides flexible drop-in placement around the reservoir without requiring extensions, and its application range extends to aquariums, laboratories, and any environment requiring reliable EC and water temperature data.
The PCT-1 is the reservoir drop-in version of TrolMaster's EC/Temp probe lineup — for inline plumbing installation in ¾" PVC tee fittings, see the TrolMaster PCT-3.
Compatibility: TrolMaster Aqua-X NFS-1 (via AMP-2), Green-X (GCS-1 via AMP-2), and Tent-X (TCS-1 via AMP-2)

FAQs
What does the PCT-1 measure?
The PCT-1 measures electrical conductivity (EC) and water temperature in a reservoir. When connected to an AMP-2 sensor board, both readings are passed to the TrolMaster controller and displayed on the sensor board's LCD and the master controller screen simultaneously — giving you real-time oversight of nutrient concentration and temperature without manual testing.
What is the difference between the PCT-1 and the PCT-3?
Both probes measure EC and water temperature via Mini DIN terminal, but they differ in installation capability and sensor board compatibility. The PCT-1 is a reservoir drop-in probe compatible with the AMP-2 board. The TrolMaster PCT-3 is a redesigned version with a reduced-diameter sleeve and threaded body that also fits directly into standard ¾" PVC tee fittings for inline plumbing installation, and is compatible with both AMP-2 and AMP-3 boards. If you need inline measurement or AMP-3 compatibility, the PCT-3 is the appropriate choice.
Which sensor boards and controllers is the PCT-1 compatible with?
The PCT-1 is compatible with the AMP-2 sensor board, which is used with the Aqua-X NFS-1 controller. It connects via Mini DIN terminal directly to the AMP-2 with no additional adapters. For setups using AMP-3-based controllers, such as the Aqua-X NFS-2 or NFS-3, the TrolMaster PCT-3 is the compatible EC/Temp probe.
Why does monitoring EC and water temperature matter?
EC measures total dissolved solids in the water, giving you a direct read on nutrient concentration — too low and plants are underfed, too high and you risk nutrient burn. Water temperature affects both nutrient uptake efficiency and dissolved oxygen levels in the reservoir. Tracking both continuously allows you to catch imbalances and correct them before they impact plant health or yield.
Can the PCT-1 be used for applications other than irrigation?
Yes — while the PCT-1 is designed for integration with TrolMaster irrigation and environmental control systems, it is equally suitable for aquarium monitoring, laboratory water quality measurement, and any other application requiring accurate, ongoing EC and temperature tracking in a liquid environment.
Should I use the PCT-1 alongside a pH probe?
Yes — EC and pH together give you a complete picture of nutrient solution quality. The PCT-1 (EC and temperature) pairs directly with the TrolMaster PPH-1 pH sensor, both connecting to the same AMP-2 sensor board. This combination provides all three critical water quality parameters — pH, EC, and temperature — in a single monitoring setup without additional hardware.
How long is the PCT-1 cable — is it enough for most reservoir setups?
The PCT-1 includes a 3.6-meter (approximately 12-foot) cable, which is sufficient for most reservoir-based setups where the AMP-2 sensor board is mounted nearby. For installations requiring greater separation between the probe and the sensor board, cable extension options should be considered.
