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