Specifications
SKU: ERANNTEX 4-in-1 Hazardous Gas Detector
The 4-in-1 Hazardous Gas Detector is a portable, high-precision monitoring device designed specifically for industrial safety, emergency response, and confined space operations. It can rapidly detect four common hazardous gases—oxygen, combustible gases, carbon monoxide, and hydrogen sulfide—simultaneously, providing leak warnings and alerts for concentration exceedances to comprehensively safeguard worker safety.
As a high-performance 4-in-1 hazardous gas detector, this device employs built-in pump-suction measurement and allows flexible switching between diffusion-only and diffusion + pump-suction detection modes. It features an automatic pump blockage alarm to ensure stable sampling and uninterrupted detection. The device supports triple alarms—audible, visual, and vibrating—and, combined with TWA/STEL occupational health alarm modes, provides real-time alerts for hazardous conditions. The instrument meets the IP68 ultra-high protection rating, offering resistance to rain, immersion, dust, and corrosion. The housing is made of high-strength, corrosion-resistant, and fire-retardant materials, with a drop resistance of ≥5 meters, ensuring stability and durability even under extreme conditions.
The 4-in-1 hazardous gas detector features 8-button quick operation and one-touch calibration, supported by intelligent designs such as automatic zero-point tracking, misoperation detection, and data recovery; it charges to full capacity in 2 hours via Type-C fast charging and stores 100,000 data points for easy viewing and export, ensuring efficient and convenient use. The device employs an intrinsically safe explosion-proof design and holds Ex ia IIC T4 Ga explosion-proof certification, fully complying with national industrial testing standards for safety, compliance, and reliable performance.
