Our GS3 sensor is a rugged soil moisture sensor that measures soil moisture, temperature and bulk electrical conductivity. Potted in a polyurethane epoxy and constructed with stainless steel pins, the GS3 is ideal for long-term outdoor use, or use in rocky or hard soils and substrates.

Out-of-the-box these sensors have an accuracy of ±3%, but can be honed in even further with a custom calibration. It is important to note that the optimal soil moisture levels for plant growth and performance will vary across soils and substrates.

PRODUCT SPECIFICATIONS

  • ACCURACY 
    • Volumetric Water Content (VWC): ± 3% in typical mineral soils with solution electrical conductivity < 10 dS/m; soil or substrate specific calibration ± 1 – 2%; 
    • Electrical Conductivity (EC): ± 5% from 0 to 5 dS/m, ± 10% from 5-23 dS/M; 
    • Temperature: ± 1°C Note: Temperature measurement may not be accurate if sensor is not fully immersed in the medium of interest, due to excessively long equilibration time.
  • RESOLUTION
