Apparatus for producing relative humidity references

Dry air or nitrogen passes through a pressure regulator (1) into a water bath (2) in a saturation chamber (3) at a given temperature (t s) of 106 degrees C. Saturated air passes through a heated pipe (V1) at a temperature (t V1) of 111 degrees C. The air passes through a condensate cooler (4) in a f...

Beschreibung
Zusammenfassung:	Dry air or nitrogen passes through a pressure regulator (1) into a water bath (2) in a saturation chamber (3) at a given temperature (t s) of 106 degrees C. Saturated air passes through a heated pipe (V1) at a temperature (t V1) of 111 degrees C. The air passes through a condensate cooler (4) in a fluid bath (5) at a temperature (t1) of 100 degrees C. Air leaves the cooler through a heated pipe (V2) at a temperature (t V2) greater than (t1). The pressure (p1) is 1432 hPa. The air passes through a heated needle valve (6) and goes through a heated pipe (V3) at a given temperature (t V3) to a measurement chamber (7) at a pressure (p2) of 990 hPa.
