Apogee Instruments - TEROS-12: Substrate Moisture, Temperature & EC Sensor (Modbus)

Brand: Apogee Instruments

The Apogee TEROS-12 measures volumetric water content, temperature, and electrical conductivity in growing media, with Modbus digital output and built-in calibrations including one optimized for soilless substrates.

Using well-tested 70 MHz capacitance and a 1.01 L volume of influence, the TEROS-12 minimizes interference from salinity and texture, making it ideal for crop steering in rockwool, coco, and soil. Its salt-resistant steel needles install easily and resist drift.

Key Features

• Measures VWC, temperature, and EC in one probe
• 70 MHz capacitance with 1.01 L volume of influence
• Built-in soilless, mineral, and dielectric VWC calibrations
• Modbus digital output; no cloud subscription required
• Rugged steel needles for repeated substrate insertion

Why Choose This Model

The TEROS-12 is the substrate sensor behind modern crop steering, giving moisture, EC, and temperature for precise irrigation decisions.

Ideal Applications

• Substrate water content and EC for crop steering
• Irrigation scheduling in rockwool, coco, and soil
• Multi-depth substrate monitoring
