Output signal shows a good linear relationship with gas concentration, enabling precise concentration readings.
Minimal performance fluctuations during long-term use, ensuring reliable detection results.
Quickly captures gas concentration changes and triggers timely alerts.
Detects most flammable gases and flammable vapors (e.g., hydrogen (H₂), methane (CH₄), propane (C₃H₈), ethanol vapors, etc.).
Exhibits certain tolerance to common poisoning substances (e.g., silicon, lead compounds), with a long service life and low attrition rate.
The GTYQ-AT0502 is designed to monitor combustible and flammable gases. Thanks to its broad-spectrum catalytic sensor, it can detect most flammable gases and vapors, including natural gas, LNG, methane (CH₄), hydrogen (H₂), propane (C₃H₈), and ethanol vapors.
No, the digital sensor component of the GTYQ-AT0502 can be replaced directly without field calibration. This feature greatly reduces maintenance difficulty and minimizes system downtime.
The device features an IP66 ingress protection rating, allowing it to perform reliably in harsh indoor and outdoor environments with severe dust and water spray. It operates within a wide temperature range of -40°C to +70°C.
Yes. The detector uses a dual-wire wiring structure for convenient installation and retrofitting. It is compatible with both XBUS 2-wire and HBUS 4-wire detectors, providing flexible replacement options for system upgrades.
The catalytic type sensor has a typical life of 36 months and offers a fast response time of less than 15 seconds (to reach 90% scale), ensuring rapid alerts in critical scenarios.
It holds complete explosion and dust ignition proof certifications, meeting strict industrial safety standards for safe operation in explosive atmospheres.
