Detector of real time movable remote measuring toxic inflammable vapour

A real-time mobile detection instrument for tele-metering toxic and inflammable gas is provided, which comprises a reflector, a drawtube, a dustproof tablet, a photo detector, a laser, a collimating mirror DSP signal processor and a laser driver. The reflector is fixed on the left end of the drawtube, the concave to the right. The interfaces of the photo detector and the DSP signal processor are fixed on the focus point of the reflector. The interfaces of the laser collimating mirror and the laser driver are fixed on the right end of the drawtube, the collimating mirror, the photo detector and the reflector are on the same axis. The laser driver and the DSP signal processor are packaged singly in a same instrument box, and connected to the photo detector and the collimating mirror separately by the cable and the fiber. The dustproof tablet is arranged between the laser collimating mirror and the photo detector, which is fixed on the drawtube. The detection instrument has high accuracy rate of the detection of
