CD4 mining use gas detector

CD4 Mining Use Multi-gas Detector

The CD4 mining use multi gas detector adopts large-scale integrated circuit technology and complies with international intelligent technology standards. This detector uses catalytic and electrochemical gas sensors to detect gases through natural diffusion, with excellent sensitivity and repeatability. Convenient use and maintenance greatly meet the high reliability requirements of equipment for safety monitoring in industrial sites such as coal mines. The shell is made of high-strength engineering plastic, which has high strength, good hand feel, and is waterproof, dustproof, and explosion-proof.
This tester is widely used in industries such as coal mine, petroleum, chemical industry, environmental protection, metallurgy, refining, gas transmission and distribution, biochemical medicine, agriculture, etc
. We provide gas detector OEM/ODMservice.
