BTYMQ-BX403 Portable Multi-Gas Detector

The BTYMQ-BX403 Portable Multi-Gas Detector is a high-performance, intelligent gas
monitoring device designed for industrial safety applications. It integrates advanced
microcontroller technology with a built-in pump sampling system, enabling fast and
accurate detection of up to 4 gases simultaneously, with common configurations including
CH₄, H₂S, CO, and O₂.

With a 4000mAh rechargeable battery providing ≥8 hours of continuous operation, IP66
protection rating, and explosion-proof design, the BTYMQ-BX403 is ideal for use in
petrochemical, mining, metallurgy, environmental monitoring, firefighting, and confined
space applications. It also features fall alarm, GPS positioning, NFC binding, and data
logging for up to 24,000 records, making it a comprehensive solution for modern industrial
gas detection needs.

Feature
