TCAV-L Averaging Soil Thermocouple Probe

The TCAV-L typically provides the average temperature of the top 6 to 8 cm of soil for energy-balance in flux systems. It parallels four thermocouples together into one 24 AWG wire. Each member of a thermocouple pair can then be buried at a different depth. The two pairs are separated at a distance of up to 1 m.
  • Used in conjunction with soil heat-flux plates and soil-moisture probes to compute total soil heat flux
