Met One Instruments Inc. is one of the leaders in research, development and manufacture of meteorological instruments, particulate monitors, data loggers and environmental software. One of the oldest instrument manufacturer's in the United States, MOI continues to provide the leading edge in instrumentation, data logging, environmental software and monitoring systems worldwide.

Projects have included entire meteorological monitoring networks for countries from Asia to the Middle East, as well as the major part of PM10 monitoring within the USA and International sites. Onsite training and commissioning for complete end-user satisfaction has always been the goal. Private industry, research institutions, universities, military and home defense organizations, as well as all levels of government environmental agencies are amongst its satisfied customers.

The company began business in 1976 as Met One, Inc. The first of several high quality 'Met Set' meteorological monitoring systems and a line of clean room monitoring instruments were introduced. Growth was brisk and the company quickly outgrew the facilities. In 1989 Met One Instruments, Inc. was formed to focus on the growing environmental market and the entire meteorological product line was transferred at that time.

The company has grown through careful planning, dedication to customer service and the ability to design and manufacture quality products. Additional growth has come about with company acquisition and joint venture partnerships.

Northwest Technology was acquired in 1991; the company specialized in fabrication operations for various semi-conductor and aircraft companies. The facilities of Northwest Technology enabled MOI to greatly expand instrumentation manufacturing. Beyond the fabrication capabilities, Northwest Technology provided key knowledge of basic robotics that was later employed in some of the air products.
