Droplet Measurement Technologies (DMT)

Darrel Baumgardner, Bill Dawson and Craig Walter founded Droplet Measurement Technologies (DMT) in 1987. DMT`s original purpose was to provide services and accessories for the Particle Measuring Systems airborne probes. In 1996, DMT received its first SBIR contract from the Office of Naval Research to develop the Cloud Aerosol and Precipitation Spectrometer (CAPS) probe. With this contract, DMT moved away from simply servicing probes and began manufacturing them. The company has grown at a steady rate that continues today. Our staff consists of 40+ scientists, engineers, technicians, consultants, and business support experts to provide continuing sales and service to our customers. Our ongoing research and partnerships with leading institutions worldwide help ensure the latest instruments and technology.
