Water-Based Condensation Particle Counter


Our water-based condensation particle counters measure the number concentration of airborne particles as small as a few nanometers in diameter. First introduced in 2005, WCPCs for laboratory and micro-contamination are licensed to, and sold by TSI Inc.

The first commercial Water-CPCs using our technology were made by Quant Instruments, but sales were soon taken over by TSI Inc.

The Water-CPC license was acquired by TSI Inc. in 2010.
