Portable gas detection devices play a vital role by protecting workers from toxic, flammable and asphyxiating gases, as well as oxygen deficiency.
At the same time, changing working practices and advances in gas detection technology have increased the importance of understanding the fundamentals of portable gas monitoring.
A solid grasp of these principles helps organisations to make informed decisions and gain maximum benefit from the latest innovations.

What is a portable gas detector?
Portable gas detectors, sometimes referred to as personal or compliance monitors, are compact, battery-powered devices designed to be worn on the body, typically within the breathing zone.
They may also be handheld or used as standalone devices. Their purpose is to provide an early warning of hazardous gas concentrations or unsafe oxygen levels in the immediate environment.
Both single-gas and multi-gas detectors are available. Multi-gas devices can monitor several hazards simultaneously using multiple sensors within a single instrument.
In pharmaceutical environments, detectors may be configured to monitor gases such as nitrogen, oxygen, carbon dioxide and hydrogen peroxide vapour, while also providing warning of oxygen depletion.
