Personal (Single) Gas Monitors

Handheld and wearable personal gas monitors

Improve worker safety with wearable and hand-held personal gas monitors. These devices clearly alert users about potential risks and enable them to take action. Our personal single gas and multi-gas monitors are effective for a range of industrial, response, hazmat, plant overhaul, oil and gas, public event safety, and environmental uses, including confined spaces, radiation detection and dose rate, and toxic gas monitoring. The monitors can detect and monitor a wide range of gases including Carbon Monoxide (CO), Hydrogen Cyanide (HCN) and Hydrogen Sulfide (H2S).

Why use a personal gas detector?

Under many circumstances chemical vapours, fumes and particulates pose a risk to workers health when they are exposed to them by inhalation, being absorbed through the skin, or swallowed. This may result in significant harm after short term high level exposure or development of disease, such as cancer, after prolonged exposure.


In the UK the Control of Substance Hazardous to Health 1999 (COSHH regulations) and HSE EH40 prescribes Workplace Exposure Limits (WELs). These WELs have legally binding status. If a substance is not prescribed under EH40 then its WEL can be found in its chemical Safety Data Sheet (SDS) under section 8. From EH40 or an SDSs Section 8, you will find Long Term Exposure Limits expressed as an 8 hour Time Weighted Averages (TWAs) and Short Term Exposure Limits (STELs), expressed as a maximum allowable average exposure over a 15 minute period.


In order to monitor these WELs it is common place to utilise a gas monitor that can measure instantaneous concentrations, STELs and TWAs. These enable an employer to effectively monitor workers exposure and can be used as part of an exposure management process.
