The GTYQ-AT0601 and GTYQ-AT0601A are self-sufficient explosion-proof combustible gas detectors built for independent operation in hazardous industrial zones. Certified for explosion and dust ignition proof performance, they comply with strict safety standards for flammable gas monitoring in high-risk locations. Powered directly by AC220V, they can run stably without relying on an external control host, making them perfect for decentralized monitoring scenarios. Infrared remote control is supported for non-intrusive debugging, allowing on-site parameter adjustment without opening the enclosure. The digital sensor assembly allows direct replacement without on-site calibration, cutting maintenance time and ensuring continuous detection. With an IP66 protection grade, they resist dust and water intrusion to adapt to harsh working environments. The base AT0601 uses a high-brightness digital tube display, while the AT0601A upgrades to an LCD screen and integrates NB-IoT communication for cloud-based centralized monitoring. Both models support offline solenoid valve detection, wireless valve connection and automatic power-failure valve shut-off, providing comprehensive safety protection for urban gas stations, industrial workshops and commercial sites.
Certified safety for high-risk hazardous zones and dust-heavy environments.
Digital sensor assembly enables fast calibration-free replacement.
AT0601A supports wireless cloud monitoring and remote safety measures.
