Airborne particle counters

The 8506 Handheld Airborne Particle Counter is pictured on the right. This handheld particle counter measures 0.3 μm to 25.0 μm with a flow rate of 0.1 CFM (2.83 LPM).

Easy to configure, up to 6 user-selectable size channels as well as temperature and relative humidity. View data and generate standardized reports on screen or via a printer, USB key, real-time through its versatile output options or export to Particles Plus data-download software. Particles Plus counters can be controlled and monitored remotely via web browser. The 8306 mass concentration mode approximates density in μg/m³ and allows for density and refractive index corrections to ensure accuracy.

Saturation point 20 times more than industry standard with 40x processing capacity.
