MF-190 Heat Flux Sensor

The MP-190 is a large area (310 x 310mm) flexible thin foil heat flow sensor. It can be easily rolled on a curved surface and attached to large surface areas. Due to its large sizes it gives properly averaged thermal conductivity results for large areas without the potential risk of measuring local hot spot effects or thermal bridges.


  • Thinnest heatflux sensor on the market
  • Large area sensor
  • Low thermal resistance

For the measurement of:

  • Evaluation of floor heating Research on heating efficiency of various lamps and other light sources
  • Investigation of the heating efficiency of drying machines, heating systems, etc.
  • Measurement of radiative heating and heating absorption of various parts of an automobile
  • Research of radiative heating of various plants

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.
