KSBH - 90A Mining Gas Detector
Introduction
The KSBH - 90A Mining Gas Detector is an essential safety device for mines. It can continuously detect combustible and toxic gases in harsh mining environments. Operating within - 40℃ to 70℃ for combustible gas and - 20℃ to 50℃ for toxic gas, it’s highly adaptable. Its explosion - proof housing (Ex ib llB T3 Gb) ensures safe use in potentially explosive areas. The detector has adjustable alarm and calibrating levels, and features self - test and self - adjustment functions, enhancing its reliability in mining operations.
