Commercial Combustible Gases Detectors

GAO’s commercial combustible gas detectors are devices used to detect the presence of flammable or combustible gases in the surrounding environment. They are designed to provide an early warning system for potential gas leaks, helping to prevent accidents, fires, and explosions. These detectors typically measure the concentration of gases such as methane, propane, butane, hydrogen, and other flammable gases and alert users through visual and audible alarms when gas levels exceed a certain threshold.

Our commercial combustible gas detectors are composed of a gas sensor, signal processing unit, display and alarm system, power source, controls and user interface, and protective housing.

The other common names of combustible gasses detectors are flammable gas detectors, gas leak detectors, gas sensors, gas leak alarms, explosive gas monitors, hydrocarbon gas detectors, methane detectors, propane gas detectors, natural gas detectors, LPG gas detectors (liquefied petroleum gas), gas leak warning systems, gas detection systems, gas analyzers, gas concentration monitors, fuel gas detectors, ignitable gas detectors, hydrogen gas sensors, explosive vapor detectors, gas detection devices, and gas PPM monitors (parts per million).

GAO Tek’s commercial combustible gas detectors have the following functions:

  • Gas Detection: Our commercial combustible gas detectors detect the presence of flammable or combustible gas in the surrounding area. It continuously monitors the air or gas mixture and identifies the presence of gases such as methane, propane, butane, hydrogen, and other flammable substances.
  • Gas Measurement: GAO’s commercial combustible gas detectors measure the concentration of combustible gases present in the environment. They provide accurate readings or measurements of gas levels, allowing users to assess the severity of the gas presence and take appropriate actions.
  • Alarm Generation: Our combustible gas detectors generate visual and audible alarms when the concentration of commercial combustible gases exceeds a predefined threshold or dangerous level. Our alarms serve as a warning to alert individuals in the vicinity about the potential hazard. The alarms can be in the form of flashing lights, loud sirens, vibration alerts, or a combination of these.
  • Safety Monitoring: GAO’s commercial combustible gas detectors continuously monitor the air quality for the presence of hazardous gases. They provide real-time data and enable proactive safety monitoring in environments where the release or accumulation of combustible gases is a concern. By monitoring gas levels, these detectors help ensure a safe working or living environment.
  • Risk Prevention: Our commercial combustible gas detectors reduce accidents, fires, and explosions caused by gas leaks or accumulation. By detecting and alerting the presence of flammable gases, these detectors enable timely intervention and preventive measures.

GAO Tek’s commercial combustible gas detectors are rugged, versatile, and precision measurement instruments. They comply with applicable industry standards such as IEC 62990-1:2019, ASTM D5197-21, and BS EN 45544-4:2016.

Our commercial combustible gas detectors help our customers comply with relevant U.S. government regulations such as:

  • Toxic Substances Control Act (TSCA)
  • Resource Conservation and Recovery Act (RCRA)
  • Clean Water Act (CWA)
  • Clean Air Act (CAA)

Our commercial combustible gas detectors help our clients in complying with relevant Canadian government regulations such as:

  • Formaldehyde Emissions from Composite Wood Products Regulations
  • Canadian Electrical Code (CEC)
  • Occupational Health and Safety Regulations
  • Natural Resources Canada (NRCan) Regulations

GAO Tek’s commercial combustible gas detectors have the following applications:

  • Industrial Manufacturing: GAO’s commercial combustible gas detectors are used in manufacturing facilities to monitor and detect the presence of flammable gases such as methane, propane, butane, and hydrogen. They help in maintaining a safe working environment by alerting workers in case of gas leaks, allowing them to take immediate action to prevent fires or explosions.
  • Oil and Gas Industry: Our commercial combustible gas detectors are used for monitoring the presence of hydrocarbons and other flammable gases. They are employed in refineries, drilling sites, pipelines, and storage facilities to detect leaks, spills, or abnormal gas concentrations.
  • Chemical Plants: Our commercial combustible gas detectors are used in these facilities by continuously monitoring the air for the presence of combustible gases. They provide an early warning system to prevent accidents, explosions, and chemical releases.
  • Mining Operations: GAO’s commercial combustible gas detectors are used to detect and monitor the concentration of flammable gases in underground mines. Methane is a common concern in coal mining, and the detectors help ensure worker safety by alerting them to high gas levels and the potential for explosions.
  • Warehouses and Storage Facilities: Our commercial combustible gas detectors are employed in warehouses and storage facilities that store flammable materials, such as paints, solvents, and compressed gases. They help in reducing fire incidents by monitoring the air for the presence of combustible gases and alerting personnel to potential leaks or hazardous conditions.

GAO’s commercial combustible gas detector can be shipped overnight within the continental U.S. and Canada, and can be shipped globally.
