Particle Counters

Particle counters
are primarily designed for use in controlled environment applications. Particle counters detect and measure individual particles as small as 0.3 microns in diameter. Our particle counters contain various size discriminators and counting capabilities to provide hand held solutions for Clean Room Certification, Filter Testing, and Process Testing. A unique feature of all particle counters is their capability to measure particles in high concentrations. This feature is useful for a number of ambient monitoring applications.

Portable Dust Monitors
are used in applications that require total amount of airborne particulate matter. Output is expressed in either micrograms per cubic meter or milligrams per cubic meter. Applications include from industrial hygiene, workplace monitoring, filter testing, and dust testing.
