【EM-3 Triple Gas Detector Product Introduction (English Version)】
The EM-3 Triple Gas Detector is an intelligent monitoring device designed for comprehensive environmental safety management, capable of simultaneously detecting combustible gases, oxygen levels, and hydrogen sulfide concentrations. With its compact structure and advanced sensor technology, this equipment delivers reliable protection for industrial operations, emergency response scenarios, and underground facility maintenance.
Equipped with three independent detection channels, the device provides real-time monitoring of gas concentration fluctuations. The combustible gas detection module supports multiple gas types including methane and hydrogen, while the oxygen sensor accurately tracks oxygen level variations. The dedicated hydrogen sulfide detection unit enables rapid response to toxic gas leaks. When any monitored parameter exceeds predefined safety thresholds, the integrated audible-visual alarm system activates immediately to alert personnel.
Constructed with durable, industrial-grade materials, the EM-3 features IP65-rated protection against dust and water ingress, maintaining stable performance in temperatures ranging from -20℃ to 50℃. The 2200mAh rechargeable lithium battery ensures up to 12 hours of continuous operation, supported by magnetic charging technology for convenient power management. A 1.8-inch color display presents real-time data through numerical readouts and trend graphs, complemented by multi-color LED indicators for instant risk level identification.
User-centric design elements include motion-activated power management to prevent accidental operation and adaptive calibration technology that extends sensor lifespan while reducing maintenance requirements. The lightweight housing (under 200g) allows flexible deployment as either a portable device or fixed monitoring unit. Compatible with mobile data analysis via Bluetooth connectivity, the EM-3 serves as a vital safety solution for petrochemical plants, municipal engineering projects, logistics warehouses, and other critical industrial environments, delivering 24/7 protection for personnel and operational safety.
