Portable gas detector for two gas

Portable gas detector for two gas
Product Detailed
Two gas detection Oil&Gas, Steel refinery Industry Coal Mine Underground Coal Mine, Pipeline, and Explosive

Brief introduction                 

BX258-LCD portable two-gas detector (hereinafter called detector) is an intrinsically safe type equipment for the continuous detection of combustible gas, oxygen, and toxic gas. This product is used in the working area of explosive-proof, rush emergency of toxic gas leakage, underground pipeline, chemical plant and mines. It can ensure the security of workers lives and the production equipment.

The detector takes gas sample by natural diffusion method. It uses high quality gas sensor as the sense organ, which has very good sensitivity and reproducibility. The built-in MCU ensures high reliability and self-adaptation ability. The excellent man-machine interface has complete functions and easy to operate. With colorful LCD, its display is more intuitionistic, abundant and clear. The compact appearance design and comfortable handle are suitable for portable use. With high strengthened engineering plastics and compound anti-slippery rubber used, it is highly strong, water-proof, dust-proof and shock-proof.
