Thermo DataRAM 4000 Area Dust Monitor-RENTAL

The DataRAM 4000 continuously monitors and logs the real-time concentration and median particle size of airborne dust, smoke, mist and fumes. In addition, air temperature and humidity are displayed and recorded. With appropriate particle discriminators, it provides measurements correlated with PM10, PM2.5, PM1.0, and respirable fractions. It's patented two-wavelength particle detection system provides the volume median particle diameter of the sampled aerosol, over a concentration range up to 400 mg/m3. Unlike typical particle counting devices, the DataRAM 4000 is totally immune to particle coincidence errors, even at the highest concentrations. Volume median particle sizes down to 0.05 µm can be measured by this unique spectral nephelometric technique. The DataRAM 4000 monitors the concentrations of fine particulates in ambient air by a combination of aerodynamic size preselection, two wavelength nephelometry, and concurrent sensing/correction for relative humidity.
