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.

The Home Health Box is a new way to thoroughly evaluate your indoor air. Using our patented air sampling technology, the programmable Home Health Box samples for particulates and gases that impact human health in the short and long term. Additionally continuous sensing of the environment allows the Home Health Box to identify the times of day and behaviors impacting your indoor air quality. The Home Health Box offers a simple alternative to lugging around a whole suitcase of air sampling equipment.

PM2.5 is monitored worldwide for ambient and personal exposure to harmful particles.

A two liter per minute inlet allows you to push your PM2.5 limits of detection lower with a higher flow rate.

The respirable size cut is a standard in many countries to monitor workplace exposure to harmful dusts. This compact inlet allows for simple ergonomic sampling in the breathing zone without the hassle of large dangling cyclone assemblies.

Easily check flow against a flow primary or get creative using the UPAS as a sampler apart from the thread on inlets. Place this adapter (left) over any of the inlets shown here and connect a flow meter (e.g., Alicat Scientific MWB-5SLPM-D) to confirm that the volumetric flow rate through the inlet and filter matches the target value.

Our universal second generation cartridge is reusable. The cartridges are a key part of what allow the full stack of inlet+ cartridge + sampler to maintain such a low profile. All of the “2nd generation” inlets shown on this sheet are used with the same 37-mm filter cartridge (right; actual size).

Want to sample onto an open-faced inlet and filter cartridge? That’s also an option! Like our size selective inlets, the open-faced inlet is compatible with the calibration adapter.

After many customer requests we have released a custom enclosure for the UPAS v2 and v2+ products. Don`t risk your hardware or your data accuracy with a DIY solution.
