UPAS v2 Ultrasonic Personal Air Sampler - User Manual

Access Sensor Technologies’ Ultrasonic Personal Air Sampler (UPAS) provides a new paradigm of streamlined, low-cost exposure assessment to indoor air pollution. The UPAS is a self-contained filter-integrated sampler featuring valve-less ultrasonic pumping technology. This technology provides substantial reductions in size, weight, noise, and cost along with increased durability over traditional sampling equipment. The UPAS is silent and light enough to be worn in the subject’s breathing zone, but can also be deployed in fixed site sampling scenarios.
