Different types of gas are used for many different purposes. The demand for gas increases by 2 percent every year and soon it will overtake even the demand for coal. One type of gas is known as calibration gas. What is calibration gas? According to SEMA Gases, calibration gas is a reference gas or a mixture of gases which are usually compressed. Typically, calibration gas consists of one gas that is enhanced by one or more components. The purpose of calibration gas is to calibrate gas analysers or gas detectors. There are several types of gas analysers, some that measure infrared gas while some measure exhaust gas by detecting carbon monoxide levels. A gas detector detects the level of gas in an area. Gas calibration standards can all be traced to international criteria. Furthermore, there are two general categories of calibration gas: zero calibration and span calibration. Zero calibration gas is free of flammable gases. On
