MF-180M Heat flux sensor

Similar to the MF-180 but waterproof and durable design for soil heat flow measurement. All sensors are extremely flat, which is a big advantage considering the minimum interference with the conditions of the testing area the thermal dynamics. The low output Voltage of the heat flow sensor can be easily converted to a 4-20mA current or higher Voltage using the MS-4..20mA converter. The mV/mA converter can be pre-programmed and optimized within the operating range compatible with common measurement equipment.


  • Waterproof and durable design
  • Teflon substrate heatflux sensor
  • Small size and profile
  • Calibration complies with JIS A 1412
