Multi-Gas Detector

GAO’s commercial multi-gas detectors are portable or fixed devices that are used to monitor the presence of multiple gases in an industrial or commercial setting. They are designed to detect the presence of a variety of harmful gases and vapors, such as carbon monoxide (CO), hydrogen sulfide (H2S), oxygen deficiency, and combustible gases like methane (CH4) and propane (C3H8). Our multi-gas detectors typically use sensors to detect the presence of gases in the surrounding environment, and they provide feedback to the user through audible, visual, and/or vibratory alarms. They may also have data logging and storage capabilities, which allow users to track gas concentrations over time and identify trends or areas of concern.

GAO’s commercial multi-gas detectors are composed of sensors, alarm system, batteries, control buttons, display, calibration components, protective housing, sampling pump, and communication ports.

The other common names of multi-gas detectors are gas detection systems, portable gas analyzers, multi-gas monitoring devices, gas sensing instruments, gas detection tools, gas monitoring systems, multi-gas analytical devices, gas sensor arrays, multi-gas monitors, environmental gas detectors, gas concentration analyzers, multi-gas measurement instruments, gas monitoring equipment, multi-gas sensing devices, industrial gas detectors, gas analyzer units, multi-gas analysis systems, gas measurement tools, gas detection instruments, multi-gas alert systems, safety gas sensors, gas detection monitors, multi-gas surveillance devices, hazardous gas analyzers, gas detection stations, multi-gas detection gear, gas detection technology, multi-gas monitoring units, compact gas analyzers, gas sensing systems, multi-gas assessment tools, gas monitoring solutions, multi-gas alarm detectors, gas concentration monitoring units, portable gas detection gear, multi-gas warning systems, gas detection equipment, multi-gas safety instruments, gas sensing arrays, and multi-gas alert stations.

GAO Tek’s commercial ammonia (NH3) gas detectors have the following functions:

  • Gas Detection: Our commercial ammonia (NH3) gas detectors are designed to detect the presence of ammonia (NH3) gas in the surrounding environment. They continuously monitor the air for ammonia (NH3) gas and provide real-time measurements of its concentration.
  • Safety Monitoring: GAO Tek’s commercial ammonia (NH3) gas detectors are used in ensuring the safety of workers and the environment. By detecting ammonia (NH3) leaks or releases, they provide early warning to alert individuals to potential hazards. This allows for prompt evacuation, mitigation of risks, and initiation of appropriate safety measures.
  • Concentration Measurement: It accurately measures the concentration of ammonia (NH3) gas in parts per million (ppm) or another relevant unit of measurement. This information helps in assessing the severity of a gas leak, determining if ammonia (NH3) levels are within safe limits, and identifying areas where additional precautions may be needed.
  • Alarm Systems: GAO’s commercial ammonia (NH3) gas detectors are equipped with audible and visual alarms to notify individuals when ammonia (NH3) gas levels exceed pre-set thresholds. The alarms serve as warning signals to prompt immediate action and evacuation if necessary.
  • Data Logging and Analysis: Our commercial ammonia (NH3) gas detectors have data logging capabilities. They can record and store gas concentration data over time, enabling analysis and tracking of trends. This information is valuable for identifying patterns, evaluating long-term exposure risks, and ensuring compliance with safety regulations.

GAO Tek’s commercial ammonia (NH3) gas detectors are rugged, versatile, and precision measurement instruments. They comply with applicable industry standards such as the ATEX directive, the IECEx scheme, UL standards, EN standards, and CSA standards.

Our commercial ammonia (NH3) gas detectors help our customers in complying with relevant U.S. government regulations such as:

  • Occupational Safety and Health Administration (OSHA) standards.
  • National Fire Protection Association (NFPA) codes.
  • Environmental Protection Agency (EPA) regulations.
  • Department of Transportation (DOT) Hazardous Materials Regulations (HMR).

Our commercial ammonia (NH3) gas detectors help our customers in complying with relevant Canadian government regulations such as:

  • Canadian Standards Association (CSA) standards.
  • Health Canada regulations.
  • Transportation of Dangerous Goods Regulations (TDG).
  • Electrical Safety Authority (ESA) requirements (specifically in Ontario).

Our commercial ammonia (NH3) gas detectors have the following applications:

  • Industrial facilities: GAO’s commercial ammonia (NH3) gas detectors are used in industrial settings, such as chemical plants, refrigeration systems, and manufacturing facilities. Ammonia (NH3) gas detectors are employed to monitor leaks or releases of ammonia (NH3) to ensure the safety of workers and prevent hazardous situations.
  • Cold storage and refrigeration: GAO’ Tek’s commercial ammonia (NH3) gas detectors are used in cold storage facilities, food processing plants, and ice rinks. Gas detectors help in monitoring ammonia (NH3) levels to ensure safe working conditions and prompt detection of leaks that could lead to exposure or equipment damage.
  • Agricultural and farming operations: Our commercial ammonia (NH3) gas detectors are used in various agricultural applications, such as fertilizer production, livestock farming, and poultry houses.
  • Waste treatment plants: Ammonia (NH3) is present in waste treatment facilities, such as wastewater treatment plants and landfills, as a byproduct of organic decomposition. Our ammonia (NH3) gas detectors are utilized to monitor ammonia (NH3) levels, prevent excessive concentrations that can be harmful to workers, and ensure compliance with environmental regulations.
  • Laboratories: Our commercial ammonia (NH3) gas detectors are employed in research laboratories and educational institutions where ammonia (NH3) may be used or produced during experiments or chemical processes. These detectors help in maintaining a safe working environment and enable prompt response to any accidental releases or leaks.

GAO Tek’s commercial ammonia (NH3) gas detectors can be shipped overnight within the continental U.S. and Canada, and can be shipped globally.
