Gas mixers, also named gas blenders, are systems able to mix two or more gases from gas cylinders. The gas mixture produced allows to avoid using expensive premixed gas cylinders.
The major application is to obtain bi- or tricomponent gas mixtures from supplied gases such as argon, oxygen, nitrogen and carbon dioxide.
Gas mixers and gas mixing systems are used in many industrial and analytical applications where a high volume of gas mixture is needed. Amongst these are protective atmosphere packaging in the food industry, welding in the automotive industry, glass manufacturing, etc.
This is particularly useful if you have high gas consumption, use rare mixtures or must change the gas composition frequently. Measuring locations can include mechanical pressure gauges such as 213.53 and also pressure sensors such as O-10.
