SpectraSensors, Inc.

SpectraSensors, an Endress+Hauser company, is the global leader of optical-based process instrumentation using Tunable Diode Laser Absorption Spectroscopy (TDLAS) and Quenched Fluorescence (QF) analyzers for on-line, real-time measurement of contaminants in process gas streams. SpectraSensors was formed in 1999 as a technology spin-off of NASA-Caltech Jet Propulsion Laboratory. For over 20 years, our products have been specifically designed to ensure operational safety, optimized productivity and high plant availability for natural gas production, transport, storage, distribution, gas processing, refining, petrochemical and specialty gas production.

Utilizing proprietary extractive TDLAS and other spectroscopic technologies, SpectraSensors delivers accurate and robust measurements with extremely fast response times resulting in improved performance, reliability and availability at a significantly lower total cost to install and own compared to alternative solutions. The Company's gas analyzers measure Moisture (H2O), Carbon Dioxide (CO2), Hydrogen Sulfide (H2S), Ammonia (NH3), Acetylene (C2H2), Oxygen (O2) and more. SpectraSensors' proprietary extractive TDL technology is now the preferred optical-based process analysis technology in the hydrocarbon processing industry.

Our commitment to providing accurate and reliable gas analysis measurement is evidence by an installed base of more than 10,000 gas analyzers around the world. Located in Southern California, our 43,000 square foot manufacturing facility is the epicenter for technology development and production.

As part of the Endress+Hauser Group, SpectraSensors has access to a strong global network of Endress+Hauser sales centers in addition to SpectraSensors' well-established distributor and representative network. Joining the Endress+Hauser Group continues to enhance SpectraSensors ability to serve its customers globally now and for decades to come.
