PM2.5 Sampler

Model No : IPM-FDS 2.5/10 Micron

Instrumex Ambient Fine Dust Sampler is designed as per USEPA guidelines for sampling of PM2.5 and PM1 0 particles in Ambient Air. The USEPA based WINS impactor separates the particles smaller than 2.5p by the principle of impaction at a regulated flow of 1 m3/hr. A critical orifice controls the flow throughout the sampling period. PM1 0 particle sampling is achieved by replacing the WINS impactor with a downtube.

Key Features

• Light Weight & Low cost monitoring Solution
• Confirms to U.S. EPA guidelines
• Choice of Sampling inlets for PM2.5, PM10 and TSP
• Construction suitable for outdoor use
