Belfort Instrument was founded in 1876 in Baltimore, Maryland.

Belfort Instrument forged its leadership role in the development of meteorological instruments through extensive cooperation with the then newly formed U.S. Weather Bureau. Through these efforts, the Belfort Observatory became the first meteorological Observatory and Instrument Laboratory in the United States by 1896.

During the 1990’s, Belfort Instrument began its research efforts around the challenges of automated weather observations. When the U.S. National Weather Service announced plans to automate routine surface weather observations, Belfort responded to the challenge and demonstrated its leadership role by designing and qualifying three new sensors for the extensive ASOS (Automated Surface Observing System) program. These advanced ASOS sensors have been deployed in over 1200 locations throughout the world. These sensors have dramatically improved system efficiency and improved the overall quality and timeliness of routine observations.
