Product Overview
A gas safety distributor named Hans Schmidt recently faced critical gas safety monitoring challenges at a application scenarios facility in Germany, Europe. The previous gas detection system relied on outdated battery-only detectors with no remote monitoring, no cloud connectivity, no auto shut-off valve integration, and frequent false alarms from cooking fumes and temperature changes, creating both safety risks and compliance issues. After evaluating multiple 4G gas detector suppliers, Hans chose Wanlin Fire Safety's Gas Detector for Tunnel for a comprehensive gas safety upgrade across multiple protected zones.

Product Introduction
Wanlin Gas Detector for Tunnel is a professional-grade 4G gas detector engineered for residential, commercial, and industrial gas safety applications worldwide. Product Overview: This advanced gas detection solution integrates catalytic combustion sensing, 4G Cat.1 cellular communication, cloud platform management, auto shut-off valve control, multi-channel alerting, and wireless interconnection into a single compact device. The system uses a high-performance catalytic combustion sensor with temperature compensation to detect combustible gases including methane, LPG, propane, butane, and city gas at 0-100% LEL range. When gas concentration reaches 10% LEL, the device triggers a low alarm; at 25% LEL, it triggers a high alarm and automatically actuates the connected solenoid shut-off valve within 1 second.
