The A30 is a compact particle counter, with a user-friendly design that can detect all aerosol particles larger than 7 nm (by request A30 can be delivered with a cut-off between 5 – 23 nm).
It can be used both as a stand-alone instrument for measuring the total particle number concentration, as well as the detector in various aerosol measurement systems. It is easy to use and handle. All settings can be quickly adjusted from the touch screen, which also displays the current concentration reading and instrument diagnostics.
The A30 can be delivered as an OEM version.
How it works
A Condensation Particle Counter (CPC) uses the same laser scatter method of detection as many of our other dust monitors. A CPC is however able to measure much smaller nanoparticles than a normal laser-based dust monitor due to the condensation chamber. In the condensation chamber, dust particles are exposed to a supersaturated solution of n-Butanol. The butanol condenses on the surface of the dust particles, causing them to grow to a sufficient size for laser scatter detection.
