Calgaz standard gas Model 1AL ; 2AL; 7HP; 6DM; 8AL; 6D; 10AL; 5ELR; 65ALR

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 measuring environment … Particularly for 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 detector equipment company recommends at least once every 3 months.In addition to MSA Gas detectors, RAE Gas detectors have their own requirements depending on different technologies

Some common Calgaz standard gas cylinder

Calgaz Standard Gas

Calgaz is a global manufacturer of calibration gases, producing a variety of calibration gases for the calibration of portable Gas detectors as well as fixed gas detector 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 portable Gas detectors or fixed Gas detectors can be tested with Calgaz standard gas.
