TEROS-21 Gen 2 water potential sensor, 5m cable, pigtail

•  Minimum: 3.6 VDC
• Maximum: 15.0 VDC

• Minimum: 2.8 V
• Typical: 3.6 V
• Maximum: 5.0 V

• Minimum: -0.3 V
• Typical: 0.0 V
• Maximum: 0.8 V

• Minimum: 3.0 mA
• Typical: 5.0 mA
• Maximum: 16.0 mA
  

• Minimum: 0.0 mA​

• Range: 0 to −100,000 kPa (1.70 to 6.00 pF)
• Resolution: 0.1 kPa
• Accuracy: ±(10% of reading + 2 kPa) from −100 to −5 kPa

NOTE: TEROS 21 Gen 2 can read up to 0 kPa when on a wetting path. The air entry of the soil limits the performance of the sensor to 0 kPa on the drying curve.

NOTE: TEROS 21 is not well calibrated beyond -100 kPa. For more information on using the TEROS 21 beyond this range, see Section 3.3.3 in the user manual
