China Marine Gas Detection System Suppliers - CCS Certified Multi-Gas Monitor Factory for Ship Safety Protection
The marine gas detection and alarm system is a professional safety monitoring solution specially customized for fishing vessels and marine working conditions, jointly developed for harsh offshore environments. Traditional manual inspection cannot achieve 24-hour real-time monitoring, leading to delayed emergency response and frequent safety accidents. This systematic gas monitoring solution completely solves the pain points of hidden gas hazards, undetected leakage and passive rescue on ships, realizing full-time and full-area active safety prevention.
85%+
According to IMO industry statistics, more than 85% of marine confined space accidents are caused by invisible gas hazards, including flammable gas explosion, oxygen deficiency suffocation, and toxic gas poisoning.
Different from ordinary industrial gas detectors, this system is professionally optimized for marine high humidity, strong salt spray, severe vibration and confined enclosed cabin environments. It can accurately monitor various common ship hazardous gases, including combustible gases (diesel vapor, liquefied petroleum gas, methane, propane, hydrogen), toxic and harmful gases (ammonia, carbon monoxide, hydrogen sulfide), oxygen (O₂) and refrigerant freon (R22). It effectively prevents major accidents such as ship explosion, crew suffocation and poisoning caused by gas leakage, and fully complies with marine safety operation specifications.
System Composition & Working Principle
This complete marine gas alarm system adopts a three-layer modular architecture of perception, transmission and control, with stable operation and convenient expansion. The whole set of equipment includes marine explosion-proof gas detectors, intelligent alarm controller, 7-inch high-definition display screen and linkage ventilation equipment. Equipped with dual power supply modes of AC220V main power and DC12V backup power, and supporting solar power supply for docked standby status, it ensures 24-hour uninterrupted monitoring without power failure dead zone.
The high-sensitivity sensors arranged in all key areas of the ship collect real-time gas concentration data, and transmit stable signals to the host controller through industrial-grade RS485 bus. Once the gas concentration exceeds the preset threshold, the system will instantly trigger sound and light alarm, display the leakage position and concentration data in real time, and automatically link exhaust fans and other safety equipment to discharge hazardous gas, realizing intelligent linkage disposal.
Core Advantages & Technical Features
1. Marine Anti-corrosion Design
The detector adopts reinforced stainless steel anti-corrosion shell with special salt spray and anti-rust treatment, featuring excellent anti-vibration, anti-impact and anti-salt spray performance. It can adapt to long-term harsh marine working conditions.
2. High-stability Intelligent Sensor
Built-in high-quality industrial sensor with strong anti-interference and anti-poisoning ability. It covers multiple detection ranges: 0~100%LEL for combustible gas, 0~30%VOL for oxygen, 0~500PPM for carbon monoxide and freon R22.

Support pre-alarm and formal alarm dual threshold free adjustment. Equipped with HD digital tube and LCD color dual display, real-time gas concentration, equipment status and alarm records are clearly visible.
4. Wireless Remote Debugging
Infrared wireless remote control function realizes parameter setting, calibration and fault diagnosis without opening the shell, greatly simplifying on-site operation and daily maintenance work for ship crews.
5. IP66 High Protection & Expansion
With IP66 waterproof and dustproof grade, suitable for humid and dusty ship cabins. Equipped with 2 groups of signal output, 4 groups of programmable interfaces and 4~20mA analog interfaces.
6. Traceability & Self-inspection
The host supports storage of 999 alarm records and 999 fault records, realizing full data traceability. It has automatic fault self-inspection function to feed back equipment abnormal information in time.
Application Scenarios
Widely applicable to all types of fishing vessels, cargo ships and marine engineering ships, covering key hazard areas such as ship engine rooms, oil storage cabins, refrigeration and cold storage rooms, sewage tanks, enclosed working cabins and equipment compartments. It is specially used for real-time monitoring of diesel vapor, LPG, oxygen, ammonia, freon and other hazardous gases, effectively avoiding explosion, suffocation and poisoning accidents, and helping ships meet international maritime safety compliance standards.
Frequently Asked Questions
What gases can this marine gas detection system monitor?
The system is designed to monitor combustible gases (such as diesel vapor, liquefied petroleum gas, methane, propane, and hydrogen), toxic gases (including ammonia, carbon monoxide, and hydrogen sulfide), oxygen (O₂) levels, and refrigerant freon (R22).
How does the system withstand harsh offshore environments?
The system features detectors built with reinforced stainless steel anti-corrosion shells treated for salt spray resistance. Combined with an IP66 waterproof and dustproof rating and a robust anti-vibration design, it functions reliably in highly humid, salty, and high-vibration marine environments.
What happens when a gas leak is detected?
Once gas concentration levels exceed the customized preset threshold, the system immediately triggers a localized sound and light alarm, displays the specific location and concentration of the leak, and automatically activates connected ventilation systems to disperse the hazard.
Does the system support backup power in case of power failure?
Yes. The system utilizes dual power supply modes, operating on AC220V main power and DC12V backup power. Additionally, it supports solar power supply during docked standby status, ensuring continuous 24-hour monitoring.
Can maintenance and calibration be performed without opening the detector casing?
Yes, the system is designed with an infrared wireless remote control feature. This allows crew members to configure parameters, perform calibration, and run fault diagnostics safely without needing to open the protective outer shell.
How many historical alarm events can the system record?
The system host supports the storage of up to 999 alarm records and 999 fault records, providing full data traceability for safety compliance audits and event analysis.
