YT-1200H-S series portable multi-gas detector is a compact, high-precision instrument designed for industrial safety applications. This mini-sized detector offers comprehensive functionality, capable of measuring four common hazardous gases: carbon monoxide (CO), hydrogen sulfide (H2S), flammable gases (CH4), and oxygen depletion (O2). Custom configurations for additional gases are available upon request.

Utilizing advanced electrochemical and catalytic combustion detection principles with diffusion sampling method, this detector provides reliable and accurate gas concentration readings. The device features zero shift of ≤±1% F.S. per year, ensuring long-term measurement stability.

Ideal for mining operations (particularly coal mines), industrial plants, confined spaces, and any environment where combustible gases like methane may accumulate. Methane, being lighter than air, tends to rise to ceiling areas where it becomes undetectable to human senses, making professional detection equipment essential for worker safety.
