Met One Instruments Inc. – The Standard in Precision Air Quality Environmental Monitoring
Environmental Monitoring is a vital component in the practice of environmental impact assessments for communities and governments.
Many modern societal activities carry a risk of detrimental effects to air quality worldwide. For more than 35 years, Met One Instruments’ precision air quality and meteorological sensors have enabled scientists to acquire vital data and environmental parameters to forecast trends and establish models to mitigate these effects.
These assessments are supported by measurements collected with our instrumentation, assisting critical decisions that impact the population worldwide – from government policy to scientific study findings.
Met One Instruments Powered by Acoem provides the industry standard in precision ambient air monitors and meteorological sensors. These sensors may be configured into systems for environmental consultants, integrators, or engineering firms. To meet regulatory compliance across the globe, many of our clients work within chemical industries, petroleum refineries, mining, milling operations, landfills, agriculture, and federal waste facilities.
We make monitoring air quality manageable by providing rugged and reliable sensors, monitors, samplers, systems, communications, and data handling solutions. Contact one of our Sales Representatives for more information! SALES@metone.com
