What are calibration gases?

Calibration gases are compressed gas mixtures consisting of a carrier gas to which one or more gaseous or vaporous additives can be added. The carrier gases are usually pure gases or gas mixtures and complement the admixtures intended for calibration as the main component. The admixtures are known as a measuring component in terms of quality and quantity, which is what makes precise and reliable measurement, calibration or testing, for example of a measuring device, possible in the first place. Therefore, it is essential to maintain the defined gas concentration but also the high demands on the purity of the starting materials.

Calibration gases are indispensable in the most diverse areas and processes of industry, technology, research and science. They are the only way to ensure the proper functioning of a wide variety of devices and instruments and thus also a warning in case of danger. Typical calibration gas applications can be found, for example, in plant construction, in fire brigade equipment or also in occupational safety - specifically in the calibration of safety-relevant detectors, sensors or devices, for example gas warning devices, multi-gas measuring devices, explosimeters, explosion protection measuring devices, CO warning systems, gas leak detectors, optical smoke detectors or gas measuring devices. In addition, calibration gases are also used to calibrate respiratory measuring devices or exhaust gas testers.
