Field-ready ultrafine particle measurement
Traditional particle counters were designed for stable, controlled bench environments, not for the jostling, tilting, and movement of real-world fieldwork. Researchers who needed mobile data often had to choose between accuracy and portability.
TSI Incorporated is closing that gap with the OmniCount™ PWCPC (photometric water-based condensation particle counter), designed for measurement on the move, and, for teams that need more, a companion system in the OmniTrak™ Smart Station that turns a single portable counter into a full multi-parameter, multi-location monitoring platform.
Built for Where the Work Actually Happens
The OmniCount™ PWCPC tolerates jostling and tilting without sacrificing accuracy, uses water as its working fluid, and offers single- or dual-channel configurations for real-time, synchronised UFP measurements. With 4+ hours of battery life and Bluetooth connectivity, it detects particles from less than 10 nanometres up to 1,000 nanometres.

From a Single Counter to a Full Monitoring System
Paired with the OmniTrak™ Smart Station, teams can monitor multiple locations at once within a 100-meter BLE range, correlating UFP data with particulate matter, gases, noise, temperature, and relative humidity, with live data viewable on-device.
Measurements across every connected device are automatically time-synchronised, exporting clean CSV files with no manual merging required. The Smart Station runs 14+ hours, and the modular system lets researchers add units as projects expand, without reconfiguring what’s already in place.
We’ll be showcasing the OmniCount™ PWCPC and OmniTrak™ Smart Station at CASANZ this year; stop by Stand 17 to see the duo in action.
