TEROS 21

The new Gen 2 version of our TEROS 21 is the world’s first full-range (−5 to −100,000 kPa) water potential sensor with legendary high accuracy, low maintenance, and low cost.

  • Easy to use
  • Improved accuracy comes from the six-point factory calibration
  • Tough, long-lasting body
  • No recalibration
  • Low salt sensitivity
  • Affordability
  • Excellent range (sensitivity from -9 kPa all the way to air dry [-100,000 kPa])
  • Onboard temperature measurement
  • Plug and play capability
  • Use with the EM60G for remote access to data
  • SDI-12 compatible

Accuracy:  Soil water potential: ±(10% + 2 kPa) from -9 to -100 kPa;  Soil temperature: ± 1 °C

Resolution: Soil water potential: 0.1 kPa; Soil temperature: 0.1 °C 2/11

Range: Soil water potential: -9 to -100,000 kPa; Soil temperature: -40 to 60 °C
