- EQ3 Equitensiometer
- Product Detail
- Company Profile
The EQ3 Equitensiometer uses class leading ThetaProbe technology to avoid the many problems of water-filled tensiometers. It measures water potential (matric potential) in the range 0 to -1000 kPa and provides an accurate loggable output. It is particularly well suited for use in dry soils.
| Measurement | Soil water potential (matric potential) and soil temperature |
| Accuracy | ± 10 kPa over 0 to -100 kPa 10% of reading over -100 to -1000 kPa |
| ± 0.5°C (0 to 40°C for temp sensor) ± 0.75°C (-20 to +60°C for temp sensor) |
|
| Soil moisture measurement range | 0 to -1000 kPa (-10bar) |
| Salinity range | Suitable for all non-saline soils |
| Temperature range | 0 to 40°C |
| Output | 0 to 1.0 V differential, non-linear (Calibration data and graph supplied with each sensor) |
| Resistance 5.8Ω to 28Ω for temp sensor | |
| Power requirement | 5-14 V, ~18 mA for 1 s |
| Environmental | IP68 |
| Sample volume | N/A |
| Dimensions and weight | 181 x 40.5 mm diameter weight: 0.3 kg (excl. cable) |
| Sensor calibrations | Individual sensor calibrations supplied Recalibration advised every 2 years (depending on use) |
| Soil calibrations | No soil calibrations required |
