Equipped with high-performance intelligent sensors utilizing intrinsic safety technology, this instrument supports multi-gas and multi-range detection tailored to exact operational conditions. The built-in intelligent temperature and zero-point compensation algorithm optimizes measurement precision, ensures superior gas selectivity, and effectively neutralizes cross-interference from background gases. Furthermore, it supports tool-free sensor interchangeability, offline calibration, and zero-point self-calibration for minimal downtime.

Engineered for extreme industrial sites, the detector utilizes a robust die-cast aluminum alloy flameproof enclosure certified with Exd II CT6, Exd II BT6, and ATEX explosion-proof ratings. With an IP66 ingress protection rating, it effectively resists dust and water exposure. Powered by a high-capacity rechargeable 8AH lithium battery, it delivers up to 36 to 80 hours of continuous, uninterrupted testing under standard configurations, ensuring reliable performance in harsh chemical and petrochemical environments.


The unit features a built-in wireless transmission module (such as LTE Cat-1 DTU) that integrates seamlessly into Internet of Things (IoT) frameworks. It enables real-time synchronization of gas concentration data and alarm signals to user mobile terminals, computers, PLC, DCS systems, and cloud platforms. When a hazard is detected, it triggers local audible-visual alarms while simultaneously driving remote receiving terminals to alert on-site operators immediately.

The large dot-matrix LCD display provides a clear, comprehensive operation interface supporting multiple units (%VOL, PPM, %LEL, mg/m³). Operators can perform alarm point settings, zero-point adjustments, and target calibrations using an infrared remote control without opening the heavy explosion-proof enclosure. This design allows safe, single-person maintenance even in active hazardous areas.

Designed to meet rigorous safety demands, the detector is widely deployed across paint booths, incineration plants, pharmaceutical workshops, wastewater treatment, petroleum pipelines, chemical processing plants, steel mills, tunnel construction, and emergency rescue operations. Its flexibility in housing up to 4 distinct gas sensors makes it an indispensable tool for comprehensive facility safety monitoring.
