Compared to the purchase of gas cylinders with pre-mixed gas mixtures, the preparation of gas mixtures on-site has some advantages. For example, the lifetime of pre-mixed gas mixtures can be limited. The costs for these pre-mixed gas mixtures are quite high, and you are not sure that the concentration of the gas is still good or that the mixture is still homogeneous.
Therefore, it can be interesting for users to prepare gas mixtures on their own with very low concentrations of specific compounds. Which yields the main argument for on-site gas preparation: as an operator you don't have to invest in cylinders of gas mixtures. It gives a lot of flexibility and freedom to calibrate an analyser in your own time.
The entire 'package' of good purchase price, improved accuracy and flexibility as well as the integrated Modbus protocol has been reason for the customer to choose for Bronkhorst devices.
