Who This Is For

  • You are building a pressurized irrigation manifold because you want precise EC readings without bulky drop-in probes.
  • You are upgrading your nutrient monitoring because standard probes require messy plumbing adapters that eventually leak.

What We Found

  • The shorter probe length is the real winner here since it actually fits in standard PVC tees without hitting the back.
  • The 3.6-meter cable gives you plenty of slack to route wires neatly along your walls without needing extensions.

What Users Say

  • Users who switched to this inline model say their signal stays rock solid even when high-power pumps are running nearby.
  • People who installed this into their main manifold say they stopped worrying about leaks from DIY sensor adapters.

TrolMaster PCT-3 Inline EC & Temperature Sensor

Managing nutrient levels in a recirculating system shouldn't involve bulky sensors and custom plumbing headaches. The TrolMaster PCT-3 is a specialized inline EC and temperature sensor designed to integrate seamlessly into your existing irrigation manifold. Unlike the standard TrolMaster PCT-1 or PCT-2, which are often used as drop-in probes, the PCT-3 ensures precision monitoring in pressurized lines without the need for complex adapters or modified plumbing.

Whether you are running a high-tech facility or a simple home setup, the PCT-3 offers the versatility needed for both inline plumbing and reservoir drop-in applications. It provides a clean, stable signal path to your controller, allowing you to maintain the perfect nutrient balance for your crops with absolute confidence. The 3.6-meter cable ensures you have the reach necessary for flexible installation across hydroponic, greenhouse, and laboratory environments.

Compatibility: TrolMaster Aqua-X (including the NFS-1 via AMP-2, and the NFS-2 or Aqua-X NFS-3 via AMP-3), Green-X (GCS-1 via AMP-3), and Tent-X (TCS-1 via AMP-3)

What's Included

  • 1 × Inline EC & Temperature Nutrient Sensor (PCT-3)

Features

🔩
Standard ¾" PVC Tee Compatible

Reduced-diameter sleeve and threaded body install directly into standard ¾" PVC tee fittings — no custom adapters required.

📏
Compact for Tight Spaces

Shortened probe length fits confined irrigation manifolds and dense plumbing runs where full-length probes physically cannot fit.

🔌
Mini DIN Direct Connection

Connects directly to sensor boards like the AMP-3 via Mini DIN terminal for a clean, secure signal path.

📡
3.6m Cable Reach

3.6-meter cable provides ample reach for flexible positioning within the irrigation system without requiring extension cables.

💧
Inline & Drop-In Compatible

Supports both ¾" PVC tee inline installation and reservoir drop-in use across hydroponics, greenhouse, and lab setups.

FAQs

What does the PCT-3 measure?+

The PCT-3 measures electrical conductivity (EC) and water temperature. When connected to a compatible sensor board, both readings are sent to the TrolMaster controller and displayed on the sensor board's LCD and the master controller display.

Does the PCT-3 include a sensor board?+

No, the PCT-3 is the probe only. It requires a compatible AMP-3 or AMP-2 sensor board to connect to your TrolMaster system.

What plumbing fittings is the PCT-3 compatible with?+

The PCT-3 is designed to fit directly into standard ¾" PVC tee fittings, which are common in most greenhouse and hydroponic irrigation systems.

Can the PCT-3 be used in a reservoir?+

Yes, the PCT-3 is versatile enough to be used either as an inline sensor within your plumbing or as a drop-in probe for static reservoir monitoring.

Which controllers is it compatible with?+

It is compatible with the Aqua-X series, including the Aqua-X NFS-1 and NFS-2, as well as Green-X GCS-1 and Tent-X TCS-1 systems when paired with the appropriate sensor board.

How long is the cable?+

The sensor features a 3.6-meter (approximately 12-foot) cable, providing plenty of length for most standard grow room and greenhouse installations.
