Sensitivity: 10 nm, Flowrate: 2.8 LPM (0.1 CFM). Purpose-built nanoparticle counter designed specifically for use in the most critical fab spaces. The NanoAir™ 10 Condensation Particle Counter (CPC) is a revolutionary new product from Particle Measuring Systems (PMS). It provides the sensitivity of a CPC with the ease of use and functionality of a traditional cleanroom particle counter. Designed to monitor ultra-clean environments, it delivers 10 nm detection sensitivity at a sample flow rate of 2.8 L/min (0.1 CFM).
