The TCAV-L typically provides the average temperature of the top 6 to 8 centimeters of soil. The probe parallels four type E thermocouples together into one, 24-gauge wire. Each member of a thermocouple pair is buried at a different depth. The two pairs are separated at a distance of up to 1 meter.
Features
- Type E thermocouple (chromel-constantan) probe
- Averages two soil temperature measurements within small vertical/horizontal area
- 2 x 2 thermocouple configuration (4 junctions total)
- Typically used in conjunction with soil heat flux plates
- 50 foot lead is recommended
