The Lasair^® III 110 Airborne Particle Counter is a laser diode-based, true 0.1 micron (μm) particle counter with a 1 CFM flow rate. It provides real-time measurement of yield-impacting particles with two configurations (portable and in-line) to meet your unique application needs. It is part of the series of cleanroom particle counters from Particle Measuring Systems.

With a comprehensive set of features and unequaled accuracy, it offers reduced operating costs and the reliability and longevity to support its three-year laser warranty. 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. Additionally, 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.

The Lasair III 110 particle counter comes in 2 models for portable and inline monitoring:

• The Portable Lasair III 110 0.1 micron particle counter can be used as a mobile counter to localize the source of particles, making this an ideal tool for ISO-14644-1 clean room certification for class 1 and 2 cleanrooms.
• The Inline Lasair III 110 0.1 micron particle counter is perfect for critical locations where continuous, uninterrupted 0.1 micron monitoring is needed. Making this an ideal application for clean room monitoring, process tool monitoring, and filter testing.

Both the inline and portable Lasair III 110 particle counters come with a full range of accessories for monitoring in different applications, including high-pressure gas with the Particle Measuring Systems’ High Pressure Diffusers. Both are also compatible with the Particle measuring systems Aerosol Manifold II to enabled clean room monitoring with a single counter.
