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
* *Sensors can be used at higher temperatures under some conditions
