This is a device for noncontact measurement of natural gas CH4 concentration based on laser absorption spectroscopy

When the instrument is working it emits a specific wavelength range the center wavelength is not the same for different gases under testof the detection laser which is diffusely reflected when it ments reflector eg the ground valves pipelines walls etc and part of the laser is returned to the detection unit of the instrument In the beam path if there is a gas leakage of the measured gas to form a gas cloud the gas cloud will be absorbed by the detection laser the amount unabsorbed light and the ratio of the amount of absorbed light and the concentration of the gas cloud into a function of proportionality through the calculation of the ratio of the inverse of the concentration of the gas cloud

Salisbury's Self-Testing Voltage Detectors allow testing to be continuous and automatic. An intermittent flash and beep confirms the detector is functioning properly. Self-Testing Voltage Detectors are used to verify live or de-energized conductors. These testers may be used with rubber insulating gloves or hot sticks using the splined universal end fitting. Testers indicate the presence of voltage with an extra bright LED light and a distinctive audible signal. It is recommended that the tester be moved closer to the conductor until a warning is indicated, or it touches the conductor, apparatus, or elbow test point. Each tester requires three C batteries (included).

Features & Benefits: Do not assume conductors that have been tested de-energized will stay de-energized. Always install proper grounding devices before working. Failure to do so may result in serious injury or death. Dimensions in. (mm): 11 x 3.5 ( 279.4 x 89 )
