The GTYQ-AT0602 is a professional independent explosion-proof detector designed for intelligent and visualized combustible gas monitoring. It adopts a tri-color visual alarm system, which clearly distinguishes normal operation, fault status and alarm conditions, greatly improving on-site management efficiency. Powered by AC220V, it can operate independently and stably, eliminating the need for additional supporting equipment and reducing overall system cost. Infrared remote control enables non-intrusive debugging and parameter setting, avoiding potential risks caused by frequent enclosure opening. The digital sensor module supports calibration-free replacement, simplifying maintenance procedures and ensuring long-term detection stability. With an IP66 ingress protection rating, it performs reliably in harsh industrial environments with heavy dust and moisture. Equipped with a high-brightness nixie tube display, it ensures clear data reading under various lighting conditions. It supports offline solenoid valve detection, wireless valve connection, automatic power-failure shut-off and direct interlock control for industrial valves. In addition, it can connect to an IoT cloud platform for remote centralized management, making it ideal for petrochemical plants, municipal gas networks and industrial park safety systems.
