Gas Detection

Rockall Safety provide a range of gas detection equipment. From portable and fixed gas detectors to flame detection systems and area monitors, the products we offer are designed for reliability, accuracy, and durability across a wide variety of industries.

We stock a wide selection of Honeywell, Dräger, MSA and Crowcon including single gas detectors and multi gas detectors. As the largest seller of Honeywell portable gas detectors in the UK, Rockall Safety offers expert advice, competitive pricing, and support to ensure you have the right device for your site.

Fixed Gas Detectors provide continuous monitoring to protect a certain area within a facility. Fixed Gas Detectors can detect a range of combustible and toxic gases. We also supply Flame Detectors that identify the presence of fire hazards with rapid response times.

Area Monitors offer a flexible solutions for monitoring larger spaces, such as warehouses, factories, or chemical plants. These devices continuously measure gas concentrations across a defined area.

To support all gas detection devices, Rockall Safety provides Gas Bottles, Gas Detection Tubes, and Spares & Accessories. From calibration gases to replacement sensors and docking stations. We work closely with industry leading brands including Dräger, Honeywell, MSA, Teledyne, and Crowcon, ensuring access to the latest technologies and high quality equipment. We have a large team of specialists that can help you select the most appropriate solutions for your site, whether you are upgrading existing systems or equipping a new facility.

FAQs

What is gas detection and why is it important?

Gas detectors monitor and identify hazardous gases in the workplace, such as flammable, toxic, or oxygen-deficient atmospheres. It protects workers from injuries, explosions, and long term health issues.

What types of gases can gas detectors detect?

Gas detectors can identify combustible gases (like methane), toxic gases (like hydrogen sulfide or carbon monoxide), and oxygen levels. PID detectors can also monitor volatile organic compounds (VOCs).

What is the difference between portable and fixed gas detectors?

Portable detectors are wearable devices that monitor gas exposure in real time for individuals. Fixed gas detectors are installed in specific locations to monitor gas levels in a specific area.

How do gas detectors work?

Gas detectors use sensors to identify gas concentrations in the air. Common sensor types include electrochemical, catalytic bead, infrared (IR), and photoionisation detectors (PID).

How often should gas detectors be calibrated or bump tested?

Gas detectors should be bump tested before each use to ensure the sensors respond correctly, and a full calibration should be every 6 to 12 months. Check the full calibration intervals with Rockall Safety as all manufacturers are different.

What is the difference between a single gas detector and multi gas detector?

Single gas detectors monitor one specific gas, ideal for focused protection. Multi gas detectors can measure several gases simultaneously, such as oxygen, carbon monoxide, hydrogen sulfide, and combustible gases.

Where should gas detectors be installed?

Placement depends on the type of gas being monitored. For example, flammable gases often rise, so detectors are placed near the ceiling, while heavier gases are monitored closer to the floor. Watch this video for more information on fixed gas detection placement: Positioning fixed gas detectors

What factors affect the accuracy of gas detectors?

Accuracy can be influenced by sensor type, environmental conditions (temperature, humidity), exposure to contaminants, and lack of calibration. Regular maintenance and correct usage help ensure reliable readings.
