Confined spaces and hazardous industrial environments require robust and reliable safety equipment. This advanced portable multi-gas detector accurately monitors EX (Combustible gas), Oxygen (O2), Carbon Monoxide (CO), and Hydrogen Sulfide (H2S) simultaneously. Equipped with temperature and humidity compensation, it guarantees precise readings across variable environmental conditions.

Designed to survive harsh industrial use, this personal gas monitor features a heavy-duty PC + TPU housing material. This rugged construction provides exceptional resistance against falls from a height. Furthermore, the intrinsically safe circuit design ensures secure operation without the risk of igniting explosive atmospheres.

The device is equipped with a bright 2.0" Color LCD (Resolution 320 * 240) that clearly displays the concentrations of all four gases. For maximum convenience in awkward positions or confined spaces, the screen features an auto-rotation function. The display can automatically rotate 180 degrees, allowing for easy viewing in special working environments.

User safety is paramount. The detector incorporates a multi-sensory alarm system, including bright LED alarm lights (Green for normal operation, Red for alarm) and a loud built-in buzzer. In emergency situations, workers can activate the one-key alarm function, and the device also features a built-in fall alarm function to alert others if the user is incapacitated. For remote tracking, it supports optional 4G, WiFi, Lora, and Bluetooth transmission.

Keep thorough and compliant safety logs with the device's immense memory capacity. It supports historical data logging of up to 120,000 records and alarm event storage of up to 30,000 records. The modern Type-C port serves as a 2-in-1 interface for 5VDC charging and data transfer. Users can perform a direct USB export to view data tables directly on a PC without the need for external software.


The multi-gas detector is securely delivered in a professional aluminum carrying case to protect the instrument during transit. We offer reliable international logistics, ensuring on-time and safe delivery worldwide with expert customs clearance support.
