Dew point hygrometers are either very precise and very expensive for example mirror dew point hygrometers or less costly but, relatively imprecise for example electrode arrangements for measuring electrical resistance. The disclosed appliance should be low-priced and at the same time have a measuring accuracy that corresponds to the measuring accuracy of mirror dew point hygrometers. A moisture sensor (8) is spatially separated from but adjacent to a condensate collector (1). The condensate collector (1) is cooled down by a determined temperature difference by a cooling/heating device (2). When during the cooling process the sought dew point temperature is crossed, liquid deposits on the …

Why it's free to use
- Filed July 26, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 26, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 26, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
