KMCD4 Mining Use Multi-gas Detector
Introduction
The KMCD4 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.
