Endress+Hauser Optical Analysis, Inc. is a manufacturer of optical-based gas sensors for the industrial process, environmental monitoring and clean technology markets.
The company's sensors measure the absorption of laser light at specific wavelengths to detect carbon dioxide and water vapor in industrial process control and environmental monitoring applications.
The heart of TDL systems is a small laser diode that produces a very specific wavelength of light tuned to a harmonic frequency of the target gas molecule in the near infrared band.
Today, Endress+Hauser Optical Analysis markets its products and technology directly to end-use customers, both in branded and Original equipment manufacturer versions.
[1] The pipeline company was then mandated to install a better class of water monitoring technology which would more accurately monitor and report moisture in their gas distribution infrastructure, prompting the company which had experienced the accident to contact Tunable Photonics which built and then delivered two prototype TDLAS measurement devices to meet federal requirements and expectations.
By the end of 2010, SpectraSensors delivered the first Water Vapor Sensing System (WVSS-II)[2] with flight evaluations by the U.S. National Weather Service, and had launched a variety of products to measure H2S, oxygen and other analytes, expanding to refining, petrochemical, gas processing and LNG markets.
