MIE DATARAM 4000 Filters so it also works asThe DataRAM 4 (Model DR 4000) continuously monitors the real time concentration and median particle size of airborne dust, smoke, mist, and fumes. In addition, air temperature and humidity are displayed. With appropriate particle discriminators it provides measurements correlated with PM10, PM2. 5 and respirable fractions. Its patented two wavelength particle detection system provides the volume median particle diameter of the sampled aerosol, over a
