Sensitivity range: 0.1 – 5.0 µm
The only true 0.1 micron particle counter
The Lasair® III 110 Airborne Particle Counter is a laser diode-based true 0.1 micron (μm) particle counter with 1.00 CFM flow rate. It provides real-time measurement of yield-impacting particles with three configurations to meet your unique application needs. Part of the series of cleanroom particle counters from Particle Measuring Systems.
With a comprehensive set of features and unequaled accuracy, the Lasair III 110 Airborne Particle Counter offers reduced operating costs and the reliability and longevity to support its three-year laser warranty.
The Lasair III 110 .1 micron Particle Counter can be used as a mobile counter to localize source of particles, and it comes with a full range of accessories for monitoring in different applications, including high-pressure gas.
It features a chemical-resistant, stainless-steel case that is easy to clean/wipe down and is designed to minimize particle traps. Patented Smart Flow technology eliminates traditional under-counting errors in manifold sampling.
Optional on-board batteries provide over seven hours of continuous mobile use, so you can run a sample for an entire shift without having to leave the cleanroom.
