Gas Analyzers

GAO’s environmental gas analyzers are used to measure and analyze the composition of gases. Our products are widely used in various industries and applications, including environmental monitoring, industrial processes, quality control, safety and health, and scientific research. GAO’s environmental gas analyzers work by taking a gas sample from the environment or a specific source and analyzing its components. It can determine the presence and concentration of different gases, such as oxygen, carbon dioxide, nitrogen, methane, hydrogen, and various pollutants.

GAO’s environmental gas analyzers are composed of a signal processing unit, gas sampling system, control and display unit, power supply, data logger, and calibration system.

The other common names of gas analyzers are gas chromatographs, gas detectors, gas sensors, gas spectrometers, gas concentration analyzers, gas composition analyzers, gas monitors, gas measurement devices, gas quality analyzers, gas inspectors, gas content testers, gas composition meters, gas concentration detectors, and gas speciation instruments.
