Standard specifications for use as HumidityAnalyzer
Description : The Zirconia Oxygen analyzer can also beused to monitor the absolute humidity in anenvironment where standard air is mixedwith water vapor. Standard air consists of79% Nitrogen and 21% oxygen. If the air ismixed with Water vapor, the vol% ofoxygen decreases as the vol% of Waterincreases. The Zirconia based Oxygenanalyzer is therefore very useful as ananalyzer for moisture content of the samplegas. Both the ZR402 and the ZR202 canbe software switched from Oxygen analysisto Humidity analysis.
Sample composition : The sample gas may only contain a mixtureof Oxygen, Nitrogen and Water.
Performance : The performance specifications aredetermined by the primary measurement:the measurement of Oxygen. The possibleerrors in humidity units can be calculatedfrom the possible errors in the Oxygenanalysis.
Range : 1. Percent by volume: range 0- 100%,minimum span 0- 25 vol%2. Weight Ratio: kg H2O/ kg dry air: range1- 1.00, min span 0- 0.200 kg/kg dry air3. Dew point: range 0- 100 ºC4. Relative Humidity: range 0- 100%
