The GTYQ-XP3000 is a durable explosion proof combustible gas detector designed for long-term stable monitoring in harsh industrial environments. It adopts an explosion and dust ignition proof structure, complying with international safety standards for flammable gas detection. The dual-wire outlet design simplifies wiring and installation, making it suitable for large-scale deployment in industrial parks and petrochemical bases. Its digital sensor assembly supports plug-and-play replacement without on-site calibration, ensuring consistent detection performance and reducing maintenance workload. With an IP66 protection grade, it resists dust, moisture and water spray, maintaining stable operation in severe working conditions. The detector is equipped with an LCD screen to display real-time gas concentration values, enabling on-site operators to quickly grasp working status. It supports interchange with 3/4-wire 4-20mA detectors from other manufacturers, facilitating system upgrades and compatibility. It is widely used for natural gas and LNG monitoring, providing a cost-effective and reliable solution for industrial safety monitoring.
