TSI OmniCount™ 3001 — UFP monitoring without butanol

May 27, 2026

News

What if your condensation particle counter required nothing more hazardous than distilled water — and could go anywhere you do?

TSI’s new OmniCount™ PWCPC Model 3001 does exactly that. This portable water-based CPC delivers lab-grade ultrafine particle (UFP) measurements in the field, in occupied spaces, and even in motion – without the safety constraints of butanol-based condensation particle counters.

Key highlights

Use it where butanol isn’t viable: distilled water removes flammability, odour, and handling concerns, making it suitable for occupied spaces like offices, classrooms, and clinics
Cost-effective: distilled water reduces ongoing running costs and supports more sustainable ultrafine particle monitoring
Reliable in motion: maintains measurement accuracy during jostling and tilting; hot-swappable battery with 4+ hours runtime for field campaigns
Easy to deploy: minimal training required; Bluetooth LE, USB-C, and onboard storage for seamless data management up to 200,000 particles/cm³

Awareness of ultrafine particle exposure risks in everyday workplaces is growing, and having a reliable, portable condensation particle counter on hand has never been more relevant. Fill in our contact form to discuss your monitoring requirements, or keep scrolling to find out more.
