Thermo Scientific DataRAM 4

With the DataRAM, you'll never have to wait for laboratory results to assess whether airborne pollutants have reached dangerous levels. The DataRAM real-time aerosol monitor measures mass concentrations of airborne dust, smoke, mist, haze, and fumes, while providing continuous real-time readouts of both air temperature and humidity. Large capacity onboard datalogging capability lets you save concentration data for future analysis. With optional accessories, the DataRAM can also provide respirable, PM2.5 or PM10 correlated measurements.
