High Temperature Humidity Analyzer when the option code “/HS (Set for Humidity Analyzer)” of ZR402G is selected. After that, in this manaul, the Humidity Analyzer refers to the thing which ZR22G combined with ZR402G with “/HS”. In addition, in this manual, the Oxygen Analyzer is mainly listed. When there are not mentions such as “in the case of Humidity Analyzer”, it becomes same as the Oxygen Analyzer.
