Monitor Nutrient Strength with Confidence for Healthier Crops
The TrolMaster PCT-1 Reservoir EC & Temperature Sensor provides accurate, real-time monitoring of your nutrient solution's electrical conductivity (EC) and temperature, giving growers the information needed to maintain the perfect feeding environment. Compatible with the Aqua-X, Aqua-X Pro, Aqua-X Plus, Tent-X and Green-X systems (via the appropriate AMP sensor board), the PCT-1 continuously monitors your reservoir so irrigation decisions can be based on live data rather than guesswork.
Maintaining the correct EC and nutrient temperature is essential for healthy root development, efficient nutrient uptake and consistent crop performance. Whether you're growing tomatoes, peppers, cucumbers, herbs or leafy greens, the PCT-1 helps prevent underfeeding, overfeeding and unnecessary nutrient waste, giving commercial and hobby growers greater control over every irrigation cycle. Its 3.6-metre cable provides flexible installation, making it easy to position the sensor exactly where it's needed.
Frequently Asked Questions
What does the TrolMaster PCT-1 measure?
The PCT-1 continuously measures electrical conductivity (EC) and reservoir water temperature, helping growers monitor nutrient strength and solution conditions in real time.
Why is EC monitoring important?
EC indicates the concentration of dissolved nutrients in your reservoir. Monitoring EC helps ensure plants receive the correct nutrient strength, reducing the risk of overfeeding, underfeeding and nutrient deficiencies.
Which TrolMaster systems is the PCT-1 compatible with?
The PCT-1 works with:
Aqua-X (NFS-1 via AMP-2)
Aqua-X Pro (NFS-2 via AMP-3)
Aqua-X Plus (NFS-3 via AMP-3)
Tent-X
Green-X
using the appropriate TrolMaster sensor board.
Do I need a Sensor Board?
Yes. The PCT-1 connects through a compatible AMP-2 or AMP-3 Sensor Board, depending on your TrolMaster controller. It cannot be connected directly to the controller.
Can the PCT-1 be used outside hydroponics?
Yes. While designed for hydroponic irrigation systems, it's also suitable for reservoirs used in aquariums, laboratories and other applications requiring accurate EC and water temperature monitoring.
How long is the sensor cable?
The PCT-1 includes a 3.6-metre cable, providing flexibility when positioning the sensor within your nutrient reservoir.
How does monitoring nutrient temperature benefit plant growth?
Maintaining a stable nutrient solution temperature supports healthy root development, improves oxygen availability and encourages efficient nutrient uptake, helping produce stronger, healthier crops.
Who is the PCT-1 designed for?
The PCT-1 is ideal for professional growers, commercial greenhouses and serious hobby growers looking to automate nutrient monitoring and maintain consistent irrigation performance throughout the growing cycle.
