Apr 04, 2017It is convenient for target gas detection. In this study, we developed the compact Raman lidar for hydrogen gas detection. To prevent the explosion accident of hydrogen gas, the sensor should detect the target gas of the low concentration of 1/4 of the explosion limit. In the case of hydrogen gas, its concentration is 1% [6, 7, 8]. The optical ...

A multi gas detector from Grainger ensures safe operations around tanks and pipelines by checking for even minute quantities of escaping gases. ... Carbon Monoxide low, Combustible Gases, Hydrogen Sulfide, Oxygen (2) Carbon Monoxide low, Combustible Gases, Hydrogen Sulfide.

It has an infrared light radiation source at one end of a gas sample tube and an IR detector at the other. The band of infrared radiation is very close to the absorption band of CO2. As a result, the amount of light radiation that is absorbed by the CO2 molecules is proportional to the amount of carbon dioxide in the gas …
