Individual calibration gases according to standards – precise, reproducible and traceable to SI units for your measurement and testing applications.





Using the DIGAMIX 6KM 501 gas mixing pump from Wösthoff Messtechnik, IFW Dresden produces calibration gases according to DIN EN ISO 51898 and ISO 6145-2 using the absolute volumetric method. The mixture is determined exclusively by stroke volume and stroke rate – regardless of the gases being mixed – and homogenized in specially designed mixing vessels. This makes the produced mixtures directly traceable to SI units. We produce 2- or 4-component gas mixtures in variable mixing ratios with concentrations down to the ppm range, ideal for high-precision calibration and testing applications.
