AST - Model UPAS v2 - Ultrasonic Personal Air Sampler
The sampler that started it all. This lightweight, nearly silent, 240 gram sampler collects airborne particulate matter on a 37 mm filter with continuously monitored volumetric flow. Each sampling run is accompanied by a log file that reports hardware performance and environmental information. With millions of hours sampled on these devices they have become the favorite of exposure scientists, epidemiologists and workplace safety professionals.
