For many of us working in adverse environments, turning on a gas monitor and attaching it to our lapel is second nature. If it alarms, we react appropriately and thank it for saving our lives. But how many of us stop to think about how these devices work or whether we are using them correctly?

The following series of articles have been written to address these questions and will form the basis of our latest gas testers handbook and authorised gas tester training courses.

The first article will introduce the design and main components, while subsequent papers will consider topics such as:

  • The latest technology
  • When and where gas monitors are used
  • How you select the most appropriate device for each situation

Our writing style is informal, starting with the basics and looking from a user’s perspective. However, by the end of the series all readers should understand what is required of a competent gas tester or as many organisations describe them, an “Authorised Gas Tester (AGT).”

As you read through each article, look out for basic gas monitoring principles highlighted in italics. These are gas detection truths applying to all scenarios in the gas detection world and could save your life one day.

One final thing before we start. Please provide us with feedback and any questions you have as we use these to improve future paper revisions. To do so use the form at
