MIE DATARAM 4000

Pine Item #51344

The 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 concentration range of up to 400 mg/m3. Unlike typical particle counting devices, the DR-4000 is totally immune to particle coincidence errors, even at the highest concentrations. Volume median particle sizes down to 0.05 micron can be measured by this unique spectral nephelometric technique. This patented technique provides a continuous measurement of PM 2.5, independent of particle size and moisture- without heating, diffusion drying, or denuding the sample stream.
