Rechargeable Portable Gas Detector for Combustible Gas Hydrogen 24V
The portable area gas detection and alarm device integrates gas detection, battery power, and wireless capabilities, enabling real-time monitoring of hazardous gases in confined spaces. The product also features real-time gas concentration monitoring and data monitoring, supporting remote real-time monitoring via mobile phones and PCs. This device enables wireless setup of alarm networks, achieving comprehensive alarm monitoring, real-time alarming, and alarm sharing. This ensures immediate detection of hazards and prompt evacuation.
• Multiple gas sensors can be independently activated or deactivated, effectively avoiding cross-interference between detected gases and extending sensor lifespan.
• Equipped with an embedded 32-bit ultra-low-power microprocessor for short response time, minimal detection error, and high resolution.
• Includes an infrared remote control for menu operations, enabling safe, non-invasive adjustments in hazardous environments without opening the device.
• Intelligent temperature/humidity compensation and zero-point calibration algorithms, along with fully automated software calibration (for 2+ target points), ensure measurement accuracy. Automatic startup self-test for sensors and components.
• Supports unit switching between PPM/mg/m³ and %VOL/mg/L, as well as bilingual (Chinese/English) interface switching.
• Real-time data transmission with multiple alarm methods to deliver precise local and remote wireless alarm notifications.
• High-strength aluminum alloy gas chamber design, wear-resistant and corrosion-resistant, suitable for harsh industrial environments.
• Automatic layout adjustment based on sensor quantity. Auto-storage for up to 300,000 sets of data; expandable to over 10 million sets with an optional TF storage card.
• Short-range RTU or unlimited-distance GPRS wireless transmission via built-in modules to send real-time data and alarm status to safety centers.
• Explosion-proof rating: Exd II CT6, certified by the National Explosion Protection and Electrical Safety Center.
