Explosion-proof Multi-Gas Detector Instrument with IP66 Protection for Industrial Hazardous Gas Monitoring
The Point-Type Gas Detector is engineered to detect leaks of flammable and explosive gases in real time. Built around imported high-performance sensors, it delivers fast response, high accuracy, long-term stability and excellent repeatability. The list of detectable gases is fully customizable to match on-site application requirements.
Leaks typically occur at flanged connections, welds, valves, fittings and seals. Because the primary risk emerges only after a leak begins, strict continuous monitoring is essential. The detector is installed at leak-prone locations—including double-wall ventilation ducts, fuel-tank connections and fuel-preparation rooms—and provides real-time concentration measurement to safeguard both equipment and personnel.
As a smart fixed-type gas detection instrument, it improves detection efficiency and stability while lowering installation, deployment, daily operation and maintenance costs.
- Wide detection range with broad gas-type coverage and accurate measurement
- Customized gas hoods compatible with waterproof covers, calibration covers and accessories
- Full-color LCD display with high visibility for dark-environment operation
- Rugged design with explosion-proof, anti-static, and anti-EMI protection
- Flexible connectivity with 4-20 mA, RS485, wireless and other transmission modes
- Scalable architecture for multi-point centralized management with controllers
| Location | Why It Matters |
|---|---|
| Double-wall ventilation ducts | Confined space with limited ventilation—leak accumulation is high-risk |
| Fuel-tank joints & connections | Primary leak point on fuel handling systems |
| Fuel preparation rooms | Hot-work adjacent zone with continuous fuel handling |
| Engine rooms & pump rooms | High equipment density and high-temperature surfaces |
| LNG cargo areas | Cryogenic flammable-gas risk |
