Product Applications

Industrial Safety Inspections: Routine gas monitoring in petrochemical, gas, and chemical plants

Confined Space Operations: Pre-entry environmental gas detection in tanks, pipelines, and underground shafts

Emergency Incident Handling: Rapid gas screening and assessment at leakage or fire scenes

Public Environment Monitoring: Gas safety supervision in poorly ventilated areas like underground parking, tunnels, and shopping malls


Product Usage

After power-on self-test, the device automatically enters detection mode, simultaneously monitoring concentrations of four gases.

Provides real-time alerts via sound, light, and vibration for hazardous gas exceedances.

Powered by a built-in lithium battery supporting USB charging, suitable for prolonged field operation.

Avoid condensing environments during use and perform regular sensor calibration to ensure data accuracy.


Product Advantages

Multi-Gas Simultaneous Detection: Monitors four common hazardous gases with one device, improving inspection efficiency.

High Sensitivity and Fast Response: Sensors react quickly, identifying gas changes and triggering alarms within seconds.

Portable and Durable Design: Compact and lightweight structure, ideal for carrying and field operations.

Wide Applicability: Covers industrial, construction, emergency, and other fields, meeting gas safety needs in complex environments.
