Water Condensation Particle Counting  (WCPC)

Our company’s patented technology has led to a family of instruments for measuring the number concentration of ultrafine and nanometer-sized airborne particles.Micro-Environmental WCPC 

Nanometer-sized particles are enlarged through water condensation in a thermally diffusive flow to form micrometer sized droplets that can be counted optically.  Particles as small as 3 nm (0.003 µm) can be detected.

Several models are available:
