TSI Incorporated's OmniCount™ Ultrafine Particle Counter Named a Double Winner in the 2026 OH&S New Product of the Year Awards

TSI Incorporated, a global leader in precision measurement instrumentation, software services, and workflow management, today announced that its OmniCount™ ultrafine particle counter has been named a winner in two categories of the 2026 OH&S New Product of the Year Awards. The single channel OmniCount™ ultrafine particle counter (Model 3001) was recognized in the Industrial Hygiene Exposure Assessment category, while the dual channel OmniCount™ ultrafine particle counter (Model 3002) was honored in the Respiratory Protection category.

The OH&S New Product of the Year Awards celebrate innovation across the occupational health and safety industry, recognizing products that help professionals better protect workers in the field. Winners are featured in Occupational Health & Safety magazine's editorial coverage and promoted across the publication's channels.

The OmniCount™ ultrafine particle counter gives industrial hygienists and health and safety professionals real-time ultrafine particle (UFP) and nanoparticle data in the field. Built for true portability, the instrument operates for more than four hours on battery power in any orientation, and uses a sustainable water-based design in place of isopropyl alcohol, reducing consumable costs and simplifying daily workflows. The single-channel model is designed for personal and field exposure monitoring, while the dual-channel model adds a second channel for real-time, side-by-side comparisons — a capability especially suited to respirator fit assessments and filtration efficiency testing.

"Earning recognition in two categories reflects the versatility of the OmniCount™ ultrafine particle counter platform and the real challenges it was built to solve," said Ketan Mehta, Vice President of Sales and Marketing at TSI. "Whether professionals are tracking down an unknown exposure source or verifying respirator performance in real time, this award affirms that we're giving health and safety teams tools that meet them where the work happens."

Both configurations comes with its own standalone software for connecting to the instrument, viewing live data, and exporting results. For multi-location or multi-parameter work, it can instead be integrated with the TSI OmniTrak™ multi-parameter platform, allowing UFP data to be correlated with particulate matter, VOCs, temperature, humidity, noise, and more across multiple locations simultaneously. When paired with an OmniTrak™ Smart Station, you can bring studies into TSI Link™ Report Creator alongside your other OmniTrak™ data.
