Detailed Description
CJG10 Optical interference methane tester
Measurement accuracy,
view clear, calibration
easy to use.
The application of light interference principle, can rapidly and accurately determine existence inflammable and explosive environment of combustible gas mixture concentration of methane, carbon dioxide and other gases in the air, measurement accuracy, view clear, calibration, easy to use.
The main features and use:
Optical interferometric methane detector when a basis of the principle of optical interference, measurement of concentration of gaseous methane, carbon dioxide, light portable instrument, instrument has high measure precision, easy operation, convenient use, etc. Mainly used for the existence of flammable, explosive combustible gas mixture measurement of methane concentration in working environment.
Working principle:
By light scattering of light entering the condenser focused beam of plane mirror, one part of the beam through the flat mirror reflection, refraction prism bullishness of room air arrive, refraction prism will be back after the refraction of the air chamber to the other side of the back panel and refraction to the reflection on the surface of the membrane, after reflection by reflecting membrane to reflecting prism by bending after entering the telescope system. After another part of the refraction of light beam in the plane mirror, behind the surface reflective film, through the chamber of methane by refraction prism reflecting back to the room to the plane mirror, methane after flat mirror reflection into reflection prism, together with some of these beams by bending into the telescope system. By the result of poor Yu Guangcheng, produce interference fringes on the focal plane of the objective, through the eyepiece interference fringes can be observed. When methane chamber and air chamber filled with the same gas, the interference fringe location does not move, but when the smoke into methane methane room, because the beam through the medium change, interference fringes move a distance relative to the original position. Measuring the displacement, and the content of methane in the air.
