TSI OmniCount™ Portable Water-based Condensation Particle Counter Model 3001

The OmniCount™ Model 3001 is a portable, water-based condensation particle counter (PWCPC) that delivers lab-grade CPC performance in a streamlined, small form factor configuration. It is designed for researchers and professionals who need accurate, cost-effective ultrafine particle (UFP) concentration measurements in the lab or on the go.

Built for real-world use, the 3001 OmniCount™ PWCPC maintains measurement accuracy during jostling and tilting and operates for more than four hours on battery power, making it suitable for both mobile and stationary applications where power may be limited. Bluetooth connectivity enables seamless, wireless data monitoring for efficient field and lab workflows.

By using distilled water instead of butanol, the OmniCount™ model 3001 simplifies operation, reduces consumable costs, and improves safety and sustainability. This makes it a cost-effective and affordable solution that requires minimal training, making it ideal for routine monitoring, teaching laboratories, and expanding research teams seeking reliable UFP measurements in a lightweight, easy-to-use instrument. It’s the perfect upgrade for an aging 3007 Condensation Particle Counter.
