Oxygen (O2) Gas Detectors

GAO’s commercial oxygen (O2) gas detectors are devices designed to measure and monitor the level of oxygen (O2) in the air. GAO’s oxygen (O2) gas detectors work by using sensors to detect the concentration of oxygen in the air. The sensor generates an electrical signal proportional to the oxygen concentration, which is then processed by the detector’s circuitry. The detector may have a display that shows the oxygen level in real-time, and an alarm that sounds when the oxygen level falls below a preset threshold. GAO Tek’s oxygen (O2) gas detectors are used for reducing injuries, illnesses, and fatalities that can result from exposure to low oxygen levels.

GAO’s commercial oxygen (O2) gas detectors are composed of sensor, circuitry, display, alarm, power supply, and housing.

The other common names of oxygen (O2) gas detectors are O2 gas sensors, oxygen gas monitors, O2 gas alarms, oxygen gas analyzers, O2 gas detectors, O2 gas meters, oxygen gas concentration monitors, oxygen deficiency monitors, O2 gas leak detectors, O2 gas alert systems, O2 gas safety devices, oxygen gas level sensors, O2 gas sensing equipment, oxygen gas surveillance systems, O2 gas measurement instruments, oxygen gas monitoring devices, O2 gas presence detectors, oxygen gas early warning systems, O2 gas detection units and oxygen gas alarm systems.

GAO Tek’s commercial oxygen (O2) gas detectors have the following functions:

  • Early detection of oxygen-deficient environments: GAO’s commercial oxygen (O2) gas detectors can detect the presence of oxygen-deficient atmospheres before they become dangerous to workers or occupants of a facility. This early detection allows for quick corrective actions to be taken to reduce harm.
  • Protection of human health and safety: Our commercial oxygen (O2) gas detectors are designed to help protect workers and the public from the harmful effects of oxygen deficiency. By monitoring the oxygen levels in the air, GAO commercial oxygen gas detectors can trigger alarms and alert personnel to evacuate or take other safety measures.
  • Compliance with regulations: Many industries are required to comply regulations regarding oxygen levels in the air. GAO’s commercial oxygen (O2) gas detectors can help ensure that facilities meet these requirements and avoid penalties or fines.
  • Maintenance of quality control: In some industries, oxygen levels are critical for ensuring product quality and consistency. GAO Tek’s oxygen (O2) gas detectors can help maintain appropriate oxygen levels to reduce production issues and ensure product quality.
  • Real-time monitoring: GAO’s commercial oxygen (O2) gas detectors provide real-time monitoring of oxygen levels, allowing personnel to respond quickly to changes in the oxygen concentration. This is important in industries where oxygen levels can change rapidly or unexpectedly.

GAO Tek’s commercial oxygen (O2) gas detectors are rugged, versatile and precision measurement instruments. They comply with applicable industry standards such as ANSI/ISA-12.13.01-2013, EN 50104, IEC 60079-29-1, UL 2075, and NFPA 72.
