Product Description
Point Type Gas Detector Instrument BV Type Approved for Marine Offshore Gas Leak Detection and Operational Safety Control
Point-Type Gas Detector - Gas leaks are among the core safety risks to lives and assets in the marine and offshore sector. As a BV type-approved gas detection device, the Point-Type Gas Detector is increasingly the first choice of shipowners, shipyards and offshore operators.
Product Overview
The Point-Type Gas Detector is designed for real-time detection of flammable and explosive gas leaks. Built around imported high-performance sensors, it delivers fast response, high accuracy, long-term stability and excellent repeatability, with gas types customizable to site conditions.
Leaks typically occur at flange connections, welds, valves, fittings and seals, and the danger only becomes visible after the leak has happened. Installed at high-risk points — including double-wall ventilation ducts, fuel tank connections and fuel preparation rooms — the detector provides real-time concentration readings to protect the vessel and its crew.
As a smart fixed gas detection instrument, it improves detection efficiency and stability while cutting installation, operation and maintenance costs.
Key Features
- Wide detection coverage - a full range of gas types with accurate measurement
- Customizable gas shield - compatible with weatherproof and calibration covers for easier on-site use and calibration
- Full-color LCD display - highly visible, even in low-light environments
- Rugged design - explosion-proof, anti-static and EMC-resistant for demanding sites
- Flexible communication - 4-20 mA, RS485 and wireless transmission options
- Scalable architecture - centralized management of multiple points via controllers
Typical Applications
- Double-wall ventilation ducts (confined spaces with high leak accumulation risk)
- Fuel tank connections and joints (primary leak points in fuel systems)
- Fuel preparation rooms (adjacent to hot work, continuous fuel handling)
- Engine rooms and pump rooms (dense equipment, many hot surfaces)
- LNG cargo areas (cryogenic flammable gas risk)

Why Choose a BV-Approved Product
Equipment must pass classification society type approval before being installed on marine and offshore vessels. The Point-Type Gas Detector has received BV type approval as part of the gas detection and alarm system, meaning its design, testing and production have all been validated by an international authority and it can be used on classed vessels worldwide.
BV Type Approval - A Dual Guarantee of Quality and Compliance
In the marine and offshore sector, gas detection equipment can only be installed onboard after passing type approval by an internationally recognized classification society. This product holds a Type Approval Certificate issued by Bureau Veritas (BV), confirming that its design, manufacture and performance fully meet the classification requirements for international voyages and offshore installations.
