Met One Instruments Inc. entered the particulate monitoring market in 1995. In a few short years, we have become a major player in ambient air monitoring around the world. The BAM 1020, the portable E-BAM and the E-Sampler are the preferred instruments for government agencies and industry domestically and overseas. They are user-friendly, accurate, robust, unique and low-maintenance. The E-BAM and E-Sampler technology has no competition.

PARTICLE COUNTERS AND DUST MONITORS

PARTICLE COUNTERS
Met One’s hand held 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 Met One particle counters is their capability to measure particles in high concentrations. This feature is useful for a number of ambient monitoring applications. The 9012 Profiler for example, is a particle counter that looks for specific particles in high concentration ambient environments.

DUST MONITORS
Met One’s 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 duct testing.
