Inside the Particulate Monitor – Filter Samplers
Some time ago, OPSIS published descriptions on how some well-established types of gas analysers work, namely those based on spectrometers, interferometers, and tuneable diode lasers. They all utilize absorption of light to determine the concentrations of gaseous pollutants such as nitrogen oxides (NOX), sulfur dioxide (SO2), hydrogen chloride (HCl), ammonia (NH3), and many more. The same ...

High Volume Enzyme Dust Air Sampling Systems
The DF-804E-30 series high volume enzyme dust air sampling systems are designed for remote unattended continuous air sampling applications. The DF-804E-30 Series Air Samplers feature a brushless motor with electronic motor speed control that maintains a user selectable flow rate. The flowrate range attainable through the filter media is dependent upon the air porosity of the filter media. The ...
