Sensor Board to connect sensors to NFS-1 controller

Live pH, EC & Temperature Sensor Board for Controllers

Checking pH and EC with a handheld meter only shows conditions at that one moment, and problems that develop between checks can go unnoticed until a crop already shows stress. The AMP-2 sensor board replaces that spot-checking with continuous monitoring, connecting precision pH, EC, and temperature probes to a TrolMaster controller for live readings and automatic alerts.

Once wired in, the board displays current values on the controller and can send 24/7 notifications if any reading drifts outside the limits a grower sets, mounting on a DIN bracket with BNC and mini-DIN terminals for standard probe connections.

Key Features & Benefits

• Live pH, EC & Temperature Readings — replaces manual handheld meter checks with continuous monitoring.
• DIN Bracket Mounting — mounts securely near a reservoir or controller.
• BNC & Mini-DIN Terminals — connects standard precision probes without adapters.
• 24/7 Limit Notifications — alerts growers if pH, EC, or temperature drifts out of range.

Who Should Use the AMP-2 Sensor Board

Growers running hydroponic or fertigation systems who want continuous pH and EC monitoring, rather than spot-checking with a handheld meter, will find the AMP-2 suited to that need.

About TrolMaster

TrolMaster's Hydro-X environmental-control platform, built by ThinkGrow Agricultural Technology in Sacramento, California, extends into fertigation monitoring through sensor boards like the AMP-2, feeding pH and EC readings back to the main controller.

Frequently Asked Questions

What does the AMP-2 measure?

pH, EC, and temperature, using connected precision probes rather than a built-in sensor. Readings display on the controller continuously instead of only at the moment of a manual check.

What probes does it support?

TrolMaster precision pH and EC/temperature probes, connected via BNC and mini-DIN terminals without needing separate adapters. Check current TrolMaster documentation to confirm probe and controller compatibility before ordering.

Does the AMP-2 send alerts?

Yes, it can send 24/7 notifications if readings move outside the limits a grower configures. That catches drift between manual checks rather than only at the next scheduled test.

How is the AMP-2 mounted?

Using a DIN bracket, typically installed near a reservoir or control panel. That fixed mounting keeps the wired probe connections stable during ongoing use.
