Active control of the relative humidity from 10 to 80 % and temperature from -10 to 50 °C

Air conditioning

The MFP 3000 HF provides exceptionally stable data on air conditioning. This includes an isothermal measuring chain to prevent evaporation and condensation effects of particles in the test channel and during sampling and particle measurement. For this reason, the MFP 3000 HF was equipped with active cooling and heating elements, which allows the air conditioning to be almost independent of the climatic conditions in the lab.

Aerosol generation
The modular system of the MFP 3000 series enables the use of different test aerosols like salt particles, DEHS particles, and test dusts like ISO A2 Fine. Aerosol generation is characterized by extremely high consistency in the aerosol concentration and the particle size distribution emitted.
The aerosol measurement from 5 nm to 40 µm
For the first time, the U-SMPS particle sizer has been integrated into the MFP 3000 series to measure nanoparticles from 5 nm to 1 µm. The MFP 3000 HF has automatic manual switching between rawand pure gas measurement points.
The light scattering spectrometer Promo^® 3000 HP performs precise particle measurements in the range from 200 nm to 40 µm and, depending on the choice of sensor, also in high concentrations up to 5000 mg/m³ (SAE Fine) or low concentrations for determination of the initial fraction separation efficiency.
Automation
The MFP 3000 has an integrated mass flow controller to control the volume flow. The FTControl filter test software automatically monitors and controls the volume flow rates. The data from the integrated sensors – such as the volume flow, temperature, relative humidity, and differential pressure at the filter – are also recorded automatically during the filter test.

Sampling and layout

The vertical layout allows even large particles (up to 40 µm) to make their way onto the filter medium. On the raw and clean gas side, isokinetic sampling probes are provided for the raw and clean gas sensor.
