What Met One Instruments Inc. does

Met One Instruments Inc., founded in 1985 and headquartered in Grants Pass, Oregon, is a precision electronic instrumentation manufacturer specializing in air quality, particulate, gas, black carbon, and meteorological monitoring. The company operates as a subsidiary of Acoem, a global environmental monitoring group, and sells under the brand "Met One Instruments Powered by Acoem." Its product portfolio centers on beta attenuation mass monitors (BAM-1020, BAM-1022, BAM-1022 PLUS, E-BAM, E-BAM Plus), optical particulate monitors (OPX 1025 with proprietary RealPM algorithm), the Serinus gas analyzer line covering O3, CO, CO2, NOx, NH3, SO2, H2S, and TRS, multi-wavelength black carbon analyzers (BC 1054, BC 1060/1065, C-12), handheld and bench-top particle counters for cleanroom compliance, sonic anemometers and weather stations, plus calibration equipment, accessories, and the COMET Cloud data service. Underlying measurement technologies include beta attenuation, optical light scatter, laser diode, chemiluminescence, NDIR, UV absorption, CAPS spectroscopy, sonic anemometry, and tape-based optical attenuation.

The company serves regulatory agencies (US EPA, MCERTS, TÜV, CE-certified instruments), industrial manufacturers (fenceline and process monitoring), cleanroom operators in semiconductors, biotechnology, pharmaceuticals, electronics, and medical/hospital settings, indoor air quality applications, climate researchers, and emerging segments such as data centers and smart cities. Revenue is generated through quote-based direct sales of hardware instrumentation, complemented by recurring software (Comet, Air Plus), calibration accessories, and the COMET Cloud cellular data service; pricing is not publicly disclosed. Distribution combines a US-based direct sales team with Acoem's global reseller network, supported by the Met One Academy training program, the Support HUB service portal, and an annual conference and exhibition circuit.
