A multi gas detector can come in many shapes, sizes and sensor configurations, which can cause some confusion with first time buyers. A multi gas detector is a portable device designed to detect multiple gases simultaneously. A portable gas detector is usually the last line of defence to alerting operators of dangerous gas leaks. The most common sensor configuration for a multi gas detector is carbon monoxide, hydrogen sulphide, flammable (infrared or pellistor) and oxygen.

Always seek advice

As always, you are buying a safety device that is designed to provide early warning of potential gas leaks and ultimately save your life. When purchasing your monitor, be sure that the monitor reflects the requirements of your application and gas hazards. For example, confined spaces are exactly that, they are limited on space and can restrict movement. Therefore you want your confined space monitor to be light weight and unobstructive.
