KMBH - 4A Construction Site Gas Detector
Introduction
The KMBH - 4A Construction Site Gas Detector is essential for construction sites where gas hazards may occur. It continuously and simultaneously detects combustible gas, O₂, and two types of toxic gases. With a natural diffusion sampling method and high - sensitivity sensors, it offers accurate and repeatable measurements. The 32 - bit MCU provides high reliability and adaptability to the dynamic construction environment. The large LCD clearly shows real - time gas levels and system status. Its compact design and light weight make it convenient to carry around construction sites. Constructed with high - strength materials, it’s waterproof, dustproof, and explosion - proof, protecting construction workers from gas - related risks.
Product Features
1. Simultaneous multi - gas detection to enhance construction site safety.
2. Compact and portable design for easy on - site use.
3. Robust build to endure construction - site conditions.
