Gas Detectors

Gas detection is an important part of home safety and an essential part of commercial and industrial safety systems. Gas detectors are also known as gas analysers, gas meters or gas leak detectors, but they all have the same main function of detection of any hazardous gas leaks, oxygen depletion or the presence of emissions (toxic or flammable gases) are found.

Why would you need a gas detector?

A gas detection unit provides you with peace of mind and real-time 24/7 monitoring. They are available as handheld portable gas detectors or can be fixed or mounted to walls and ceilings.

How do they work?

There is a sensor inside the detector that will measure and monitor the concentration of certain hazardous gases that are in the air, and if gases are detected above a certain level which the sensor is set to an alarm will be triggered for evacuation. The alarms can be audible, visual or both, to ensure that all individuals can be alerted for evacuation. The gas detector could also send a signal to the building operations department in industrial/commercial buildings so people are aware of the danger even if they are not in the affected area.

What do they detect?

Gas detectors are categorized by the type of gas they detect; however, some are also multi gas detectors. Within this broad range, they are further defined by the technology they use:

  • Catalytic and infrared sensors detect combustible or flammable gases
  • Electrochemical and metal oxide semiconductor technologies generally detect toxic gases
  • Some common gases that can be detected are:

  • Carbon Monoxide
  • Chlorine
  • Carbon Dioxide
  • Ammonia Hydrogen Sulphide
  • Methane
  • Nitrogen Dioxide
  • Butane Gas
  • Natural Gas
  • How do I maintain my gas detector?

    Most gas detectors are battery operated for safety reasons, so it is important to perform regular checks on battery life and complete maintenance checks, the same way you would with a fire alarm.

    Are there any certifications to be aware of?

    Some gas detectors will offer ATEX certification (Atmospheres Explosibles) which is an EU-regulated standard designed to ensure the safety of equipment or products being used in potentially explosive environments.
