YBJ Flameproof Laser Pointer is an instrument integrating electronics, optics and precision machinery. With beautiful appearance, small size, light weight, explosion-proof and so on. The instrument is mounted in a fixed manner and can be fastened to the anchor rod by means of a suspension set. The instrument can be arbitrarily adjusted in the 360° range, with fine adjustment; convenient adjustment and reliable braking. The product adopts independent research and development of optical system, can use red, green two light source, spot size, range to meet the construction needs of the mine. The instrument adopts AC-DC conversion power supply module, AC wide voltage AC80V ~ AC245V power supply, with protection function.
