Calgaz standard gas purpose: Any measuring device after a while needs to be recalsured for many reasons such as: Changes in components, changes in the use environment, contamination from the measurement environment … Particularly gas detectors, calibration is even more necessary because most sensors work according to the principle of electrolymization, the chemical composition will change after each measurement, or change itself due to natural chemical reactions. Depending on the manufacturers, the recommended time varies, as the BW gas detector company requires a period of at least 180 days, the ISC gas detection equipment company recommends at least once every 3 months. In addition, MSA gas detector company, RAE gas detector company has its own requirements depending on different technology

Calgaz Standard Gas Company

Calgaz is a global manufacturer of calibration gases, producing a variety of calibration gases for the calibration of handheld gas detectors as well as fixed gas measuring systems.

There are a few standard gas manufacturers on the market such as Calgaz, Gasco…, but most gas detectors use Galgaz’s sample cylinders for various reasons. Therefore, all handheld gas detectors or fixed gas detectors can be tested with Calgaz standard gas.
