Explosion-Proof Point-Type Gas Detector with Real-Time Detection and IP66 Protection for Industrial Safety
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 customisable 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 the vessel and its crew.
As a smart fixed-type gas detection instrument, it not only improves detection efficiency and stability, but also lowers the cost of installation, deployment, daily operation and maintenance.
- Wide detection range—broad gas-type coverage with accurate measurement
- Customised gas hoods—compatible with waterproof covers, calibration covers and other accessories
- Full-colour LCD display—high visibility, adapts to dark-environment operation
- Rugged design—explosion-proof, anti-static, anti-EMI for complex field environments
- Flexible connectivity—4-20 mA, RS485, wireless and other transmission modes
- Scalable architecture—works with controllers for multi-point centralised management
| 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 |
Available in seven variants to suit specific application requirements.
| Item | Specification |
|---|---|
| Power consumption | ≤ 5 W (with audible & visual alarm) |
| Protection rating | IP66 |
| Display | LCD |
| Explosion-proof marking | Ex db IIC T6 Gb (GQ-C100B-1: Ex db ia IIC T4 Gb) |
