In response to customer needs, we have partnered with Air Products, a leading global supplier of industrial gases. Calibration gases are special industrial gases or gas mixtures with guaranteed accuracy, and therefore each calibration gas also has an accuracy certificate. As the name suggests, these gases are used for the calibration and control of electronic gas detectors. A calibration gas or gas mixture is characterized by reliable and consistent quality. These products are supplied in small, disposable cylinders. Calibration gases are specially tailored to the requirements of devices for measuring gas concentrations in a given environment. Pressure cylinders may contain, among others, calibration gas such as methane, propane-butane, carbon monoxide, hydrogen, and others. A wide range of calibration gases is used for the calibration and control of electronic gas detectors. They are most commonly used for checking the gas detection function of analytical instruments. Disposable cylinders with calibration gases can be taken anywhere and are suitable for calibrating gas detectors at their installation site.
