Portable Gas Detectors
At Rockall Safety, we are proud to be Honeywell’s largest distributor in the UK, bringing over 20 years of experience in portable gas detection to our customers.
Portable gas detectors are designed to provide instant alerts when hazardous gases are present. Our range includes single gas detectors, perfect for monitoring a specific hazard such as carbon monoxide or hydrogen sulfide, as well as multi gas detectors that can simultaneously detect oxygen levels, flammable gases, and toxic gases. For industries dealing with volatile organic compounds, our photoionisation detectors (PID) provide accurate measurement of VOCs.
We partner with leading brands such as Honeywell, Drager, Industrial Scientific, Crowcon, and more to bring you the best portable gas detection equipment available on the market.
Rockall Safety have a large internal team here to support you. With decades of experience, we can advise on the most suitable devices for your specific application. Our team can also provide guidance on maintenance, calibration, and accessory requirements to keep your detectors operating at its best.
If you have any questions about portable gas detectors, please contact our team at 02920 759 683 or fill in the form here. We would be happy to help you choose the right one for your needs.

FAQs
A portable gas detector is a handheld/wearable device designed to monitor the breathing zone for hazardous gases.
Hydrogen sulphide (H₂S), Carbon monoxide (CO), Oxygen (O₂), Combustible gases (LEL), Volatile organic compounds (VOCs), Ammonia (NH₃), Chlorine (Cl₂), Hydrogen (H₂) and many many more!
A single gas detector monitors one specific gas, such as H₂S or CO. A multi gas detector monitors multiple gases at the same time, typically four gases such as O₂, CO, H₂S and LEL.
A single gas detector should be used when there is a known and specific gas hazard present on site. They are ideal for personal monitoring in environments where one particular gas poses a threat, such as hydrogen sulphide (H₂S).
A multi gas detector should be used in environments where more than one atmospheric hazard may be present. They are commonly used in confined space entry, where oxygen depletion, toxic gases and combustible gases can all pose serious risks at the same time.
A PID (Photoionisation Detector) gas detector is a specialised portable gas detector designed to detect volatile organic compounds (VOCs) at very low concentrations, often measured in parts per million (ppm) or even parts per billion (ppb).
A bump test is a quick functional check where gas is applied to confirm the detector alarms correctly.
Calibration adjusts the sensor to ensure accurate readings against a known concentration of gas.
Most portable gas detectors used in hazardous areas are ATEX certified for use in explosive atmospheres.
If you are working in a hazardous zone (Zone 0, 1 or 2), you must ensure the detector is appropriately certified.
IP65 offers protection against dust and water jets. IP67 offers protection against dust and temporary immersion. For outdoor environments, IP65 or higher is recommended.
