Technical Support

Yes. A gas detector can simultaneously detect the concentrations of multiple gases, known as a multi-gas detector. Both fixed and portable gas detectors can be customized to detect multiple gases.

For example, a common four-in-one gas detector can simultaneously detect oxygen, hydrogen sulfide, carbon monoxide, and combustible gases. Users can also choose other gases based on on-site testing needs. Gas detector manufacturers configure different sensors based on these requirements.

Yes. Using a multi-gas detector requires a basic understanding of its principles and techniques. For example, different detection methods can be categorized as optical, electrochemical, and chemichromic. Each type of gas detector operates differently, requiring an understanding of the detection process and the interactions between its components.

  • A multi-gas detector’s high-precision sensors and advanced technology make it relatively expensive.
  • It is also susceptible to environmental factors. For example, extreme heat, high humidity, and dusty environments can affect sensor accuracy and lifespan.
  • Although it can detect multiple gases simultaneously, the detection range of each gas may be limited.
  • For gas detection in certain specific gases or under special circumstances, additional specialized instruments may be necessary.

5 Essential Factors for Choosing Multi Gas Detectors
