- You are managing multiple reservoir zones because you want to check water quality across them without slow, inconsistent manual checks.
- You are maintaining nutrient balance because you need real-time and accurate data on pH, EC, and water temperature.
- The 16-foot and 4-foot RJ12 cables included in the package give you enough length to set up your connection flexibly.
- The integrated LCD screen lets you check live pH, EC, and temperature readings directly at the source.
- The onboarding addressing key lets you daisy-chain multiple units to monitor different zones independently.
- Users who shifted from manual testing to this board report fewer nutrient imbalances during critical growth phases.
- Operators with large multi-zone setups say the live LCD readout saves them trips back to the main controller.
TrolMaster AMP-3 pH, EC & Temp Sensor Board
Manually checking water quality across multiple reservoir zones is a slow, inconsistent process that often leads to errors at critical moments. The TrolMaster AMP-3 Environmental Control sensor board solves this by acting as a high-precision bridge, connecting your pH and EC/Temperature sensors directly to your central controller. This ensures you receive real-time, accurate data without the guesswork, allowing you to maintain perfect nutrient balance and water health.
Designed for professional-scale operations, the AMP-3 delivers live readings for three vital parameters simultaneously on its integrated LCD screen and your master controller. This modular system allows for easy upgrades and maintenance, as compatible probes connect separately to the board. By integrating the AMP-3 into your setup, you gain centralized oversight of your water quality, whether you are using the TrolMaster Green-X GCS-1 Greenhouse Control or the TrolMaster Tent-X TCS-1 Grow Tent Control.
Compatibility: TrolMaster Aqua-X Pro, Green-X, and Tent-X Systems

FAQs
Does the AMP-3 include pH and EC probes?
No — the AMP-3 is a sensor board that acts as a bridge between compatible pH and EC/Temperature probes and the TrolMaster controller. This modular design allows you to pair the AMP-3 with the specific sensors suited to your system.
What does the AMP-3 actually measure and display?
Once connected to compatible sensors, the AMP-3 reads and displays three parameters: pH level, electrical conductivity (EC), and water temperature. Readings appear on the integrated LCD and your master controller in real time.
Can I run multiple AMP-3 units across different zones?
Yes. The AMP-3 features an onboard addressing key that allows multiple units to be connected and individually identified within the same system, enabling independent monitoring across separate reservoirs or feed lines.
Why is monitoring pH, EC, and water temperature important?
pH controls nutrient availability, EC measures nutrient concentration, and water temperature affects uptake efficiency. Tracking all three provides the earliest warning of imbalances before they impact plant health.
How does the AMP-3 connect to the controller?
The AMP-3 connects to your TrolMaster controller via the included RJ12 cable. It includes both a 16ft and 4ft cable plus a T-shaped splitter for flexible installation.
