UPAS - Ultrasonic Personal Air Sampler
NO TUBES. NO TAPE. NO HASSLE.
Access Sensor Technologies' UPAS has enabled air sampling to become a simple process. Our air sampler allows subjects more comfort with gold standard quality data collection.
The UPAS provides a new paradigm of streamlined, low-cost exposure assessment for particulate matter 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'.
Additionally, the hassle free tubeless design uses a fully integrated filter cartridge that is easy for the subject to wear while performing daily activities. The UPAS can be quickly programmed from any tablet or phone to fit the users’ needs across various applications while providing a rich data stream from each sample.
