Freezing readings

A good air quality is decisive for the comfort of
persons. Therefore many new guidelines , e.g.
VDI 6022-3 and DIN EN 15251, are based on the
determination of the air quality. The Wöhler
FA 430 does not only determine the amount of
circulating air but it also determines the quality of
this air. According to VDI 6022-3 and DIN EN
15251 the humidity and the CO
important parameters. The Wöhler FA 430
measures these values and the volume flow at the
same time.
