This portable multi-gas detector is engineered to detect four key gases: flammable gas (LEL), oxygen (O₂), hydrogen sulfide (H₂S), and carbon monoxide (CO). With high-precision sensors and real-time data display, it ensures safe operation in hazardous environments like oil refineries, tunnels, steel plants, sewage systems, and gas pipelines.
High-Precision Sensors with Fast Response
- The portable multi-gas meter is equipped with advanced, low-power gas sensors that deliver accurate and quick detection of flammable gas, O₂, H₂S, and CO.
- The 4-in-1 handheld gas detector features a high-definition 1.8-inch screen for clear real-time gas readings, even in low-light environments.
- Multiple alarm modes: audible buzzer, flashing light, vibration, and on-screen warnings to ensure timely danger notification in any environment.
- Constructed with rugged ABS material for enhanced durability and impact resistance in harsh industrial settings.
Waterproof, Dustproof & Explosion-Proof
- IP65 waterproof and dustproof rating; explosion-proof design ensures reliable performance in hazardous working areas.
- Lightweight, pocket-sized design with intuitive interface makes it ideal for on-the-go monitoring in confined spaces or fieldwork.
- Built-in rechargeable lithium battery supports long continuous operation, reducing downtime and maintenance costs.
- Suitable for confined space entry, oil & gas, chemical plants, mining, firefighting, and environmental monitoring.
Applications
The handheld multi-gas detector is ideal for detecting flammable gases, oxygen, hydrogen sulfide, and carbon monoxide in various hazardous environments such as the oil and gas industry, utility tunnels, steel smelting plants, wastewater treatment facilities, and gas pipeline networks. It ensures worker safety and helps prevent gas-related accidents in confined and industrial spaces.

Dimension
Q1: What gases can this handheld multi-gas detector detect?
A1: This device is a 4-in-1 gas detector designed to monitor combustible gases (LEL), oxygen (O₂), hydrogen sulfide (H₂S), and carbon monoxide (CO) simultaneously. It provides real-time readings to ensure safety in hazardous environments.
Q2: Is this multi-gas detector suitable for outdoor or harsh environments?
A2: Yes, the detector is rated IP65, meaning it is dust-tight and protected against low-pressure water jets, making it ideal for rugged industrial use both indoors and outdoors.
Q3: Where can this 4-in-1 portable gas detector be used?
A3: This 4-in-1 portable gas detector is commonly used in oil and gas facilities, tunnels, steel plants, wastewater treatment stations, and gas pipeline maintenance, especially where confined space gas monitoring is required.
Tips: Does this multi-gas detector have alarms?
Yes, this handheld multi-gas detector is equipped with four alarm methods to ensure maximum safety: audible (buzzer), visual (flashing LED light), vibration, and on-screen warning messages. These alarms activate automatically when the concentration of any target gas—combustible gases (LEL), O₂, H₂S, or CO—exceeds the preset threshold. The combination of sound, light, vibration, and display ensures the alarm can be noticed even in noisy, dark, or confined environments, making it highly effective for industrial and field applications.
