GAS-1D Gas Detector For Gas Detection&Alarm System
Product Description
GAS-1D Gas Detector For Gas Detection&Alarm System
Product Introduction
This marine-grade Gas Detector is the frontline sensing component of any shipboard Gas Detection & Alarm System. Designed for continuous and reliable monitoring of hazardous atmospheres, it plays a critical role in safeguarding crew, cargo, and vessel integrity by providing early warning of combustible gas leaks, toxic vapor accumulation, or oxygen deficiency in confined spaces.
Engineered specifically for the demanding maritime environment, the detector features a robust, corrosion-resistant housing with a high ingress protection rating (typically IP66/IP67 or higher), ensuring dependable operation against salt spray, humidity, and vibration. Its advanced sensor technology delivers fast response times, high accuracy, and stable performance with minimal calibration drift, even in challenging conditions.

Core Features & Benefits
1.Targeted Gas Detection: Available in specialized versions for detecting combustible gases (LEL), toxic gases (e.g., H2S, CO), or oxygen levels (O2), allowing for precise protection in areas like engine rooms, pump rooms, cargo holds, and battery compartments.
2.Intrinsic Safety & Certification: Often designed as intrinsically safe (Ex ia/ib) for installation in hazardous zones. Complies with stringent international standards, including SOLAS, IMO MSC.1/Circ.1475, and major Class Society (DNV, ABS, LR, etc.) certifications.
3.Durable & Maintenance-Friendly: Constructed with marine-grade materials (stainless steel 316, corrosion-resistant plastics). Features easy-access sensor elements and filters to simplify routine maintenance and inspection.
4.Seamless System Integration: Outputs standard electrical signals (4-20mA, Modbus, etc.) for direct and reliable connection to the central Gas Alarm Controller or monitoring panel. Supports both conventional and addressable system architectures.
5.Versatile Mounting Options: Designed for flexible installation via wall mount, duct mount, or fixed probe, ensuring optimal sensor placement for effective gas detection in various vessel layouts.
As the essential sensing element, this Gas Detector forms the reliable foundation of a complete safety system, enabling proactive risk management and compliance with mandatory maritime safety regulations.
