Thermo Andersen TSP Sampler

TSP Mass Flow Controlled All Andersen High Volume Air Samplers feature accurate collection of total suspended particulates exceeding EPA specifications.  Air flow through a mass flow controlled system is maintained at a constant rate by an electronic probe which automatically adjusts the speed of the sampler to correct for variations in voltage temperature, pressure and filter loading. Adjustable over a range from 20 SCFM to 60 SCFM the air flow is controlled at constant standard conditions of 25 degrees C temperature and 760 mm Hg pressure within plus or minus 1 SCFM.  By maintaining an exact air flow rate through the sampler, the average concentration measured is extremely accurate and reliable. A typical Andersen TSP high volume air sampler incorporates a pressure recorder (G105) or a well-type manometer (G8WT) for flow verification. An elapsed time indicator (G901) is calibrated in hours, tenths, and hundredths meeting Federal Register specifications Vol 47 No. 234.  Andersen sampl
