2-in-1 EC + Temp Sensor for Reservoir

Monitor Reservoir EC and Temperature in One Probe

Tracking nutrient strength and reservoir temperature usually means running two separate sensors into the same tank, which adds wiring and mounting hardware for what is fundamentally one reading location. The TrolMaster PCT-1 Reservoir EC/Temp Sensor combines EC and water temperature monitoring in a single probe, connecting to an Aqua-X controller through the AMP-2 Sensor Board.

A 6-meter cable and Mini-DIN terminal allow flexible placement away from the controller, letting growers position the sensor directly in a hydroponic reservoir, aquarium, or lab setup.

Key Features & Benefits

• 2-in-1 EC and Temperature Sensing — tracks two key metrics from a single reservoir probe.
• Mini-DIN Terminal Connection — links directly to the AMP-2 Sensor Board on an Aqua-X controller.
• 6-Meter Cable Length — allows flexible placement away from the controller.
• Reservoir, Aquarium, and Lab Use — works across hydroponic, aquarium, and lab settings.
• Rated Working Conditions — operates from 32 to 122°F with working humidity up to 90%.

Who Should Use the PCT-1 EC/Temp Sensor

Growers using an Aqua-X controller who want to track both nutrient strength and reservoir temperature from a single probe, instead of two separate sensors, are the intended users of the PCT-1. It's built for light-duty reservoir monitoring rather than heavy commercial inline plumbing.

About TrolMaster

The PCT-1 connects into TrolMaster's Aqua-X sensing ecosystem through the AMP-2 board, engineered at the Sacramento, California company's headquarters as the standard entry point for reservoir-based EC and temperature readings. It's the lighter-duty counterpart to the company's heavy-duty inline PCT-2 and PCT-3 sensors.

Frequently Asked Questions

What does this sensor measure?

EC and water temperature together in one probe. Both readings come from the same physical sensor body.

What controller does this sensor connect to?

An Aqua-X controller through the AMP-2 Sensor Board. The board must already be installed for the PCT-1 to report readings.

How long is the connecting cable?

6 meters. That length allows the probe to sit in a reservoir some distance from the controller.

What settings can this sensor be used in?

Hydroponic reservoirs, aquariums, or lab setups. Its general-purpose probe design suits any tank-based liquid monitoring.

What are the working temperature and humidity ranges?

32 to 122°F, with working humidity up to 90%. Those ratings cover typical indoor grow-room conditions.
