Stainless steel version with heating for temperatures up to 250°C and humidity control


In this version, the filter holder MMTC 2000 EHF is made of V2A in order to cover a higher temperature range. The addition of heating and insulation allows filter testing at temperatures of up to 250°C.

In addition, the relative humidity can be controlled on this system up to 80% rel. humidity at a maximum temperature of 90°C.


  • Internationally comparable measurement results thanks to the widespread use of the MMTC 2000 measurement system
  • High reproducibility of the testing method
  • Different dusts from real applications can be used
  • Quick and easy adjustment of the raw gas concentration
  • Simulation of the so-called garland effect
  • Suitable for in-situ measurements
  • Online measurements of the particle size and particle concentration with the light scattering spectrometer welas® digital
  • MMTC 2000 EHF: This test rig can be heated to 250°C; the relative humidity can be set to levels up to 80% (at a temperature of 90°C).
  • Lightweight, small and mobile design
  • Easy handling, easy cleaning
  • Quick set-up time when changing the filter or test dust
  • Validation of the clear function of individual components and the overall system during pre-delivery acceptance testing
  • Reliable operation
  • Short set-up times, extremely low-maintenance
  • The unit will reduce your operating costs
