KMBH - 4S Underground Tunnel Gas Detector
Introduction
The KMBH - 4S Underground Tunnel Gas Detector is meticulously designed for underground tunnels, where gas leakage and explosion risks are prevalent. This device can simultaneously detect four types of gases. Employing the natural diffusion sampling method with high - sensitivity sensors, it ensures accurate and repeatable gas measurements. Equipped with a 32 - bit MCU, it adapts well to the complex underground environment. The CSTN colorful LCD offers intuitive and clear status displays. Its compact 130×67×30mm size and 400g weight make it easy to carry. It’s waterproof, dustproof, and explosion - proof, and can record 500 data points for further analysis.
