Based on the award winning diode laser technology developed by Southwest Sciences, a natural gas leak detector known as the ’46 Hawk is commercially available from the Southern Cross Corp (telephone 800-241-5057). This sensor detects methane through a high sensitivity optical absorption spectroscopy technique known as wavelength modulation spectroscopy. The sensor contains a small multipass cell which provides a one meter optical path. A small low power pump is used to draw sample into the cell. The sensor incorporates a custom low cost, low power, digital signal processor based electronics system developed at Southwest Sciences.
Developed in partnership with Southern Cross, the premier gas leak detection workforce service provider and manufacturer of electronic leak detection equipment in the United States. Call 800-241-5057 to order the HAWK
FEATURES
- 1 ppm to 100% gas detection range
- 3 lbs weight
- 14 hour single charge operation
- Selective to methane (natural gas)
- Extremely stable calibration
- 1 second time response
Detection of other gases using this technology is possible by switching lasers. Other gases that can be detected include water vapor, carbon dioxide, hydrogen flouride, acetylene, ammonia, and oxygen.
Mark Paige demonstrates portable natural gas leak detection with a prototype of the '46 Hawk. Mark led the development of the gas detector.
The technology embedded in this sensor was developed in part through funding from the National Science Foundation and Dept. of Energy SBIR programs (NSF grant DMI-0215797 and DOE grants DE-FG03-98ER82671 and DE-FG02-03ER83780).
