2.5.3 Measuring Humidity and Attensions
High humidity or rapid temperature change in atmosphere may cause humidity reading value to be
exceedingly high because of the condensation occurred on this sensor. Incase of the condensation,
leave a probe under atmosphere of less than 40%RH for 24 hours to dry.
Comparison: Assman Aspirated Psychrometer
The quality and accuracy of IAQ Monitor humidity measurement function is ensured by strict
calibration with traceability in Japanese National Standards of JEMIC (Japan Electric Meters
Inspection Corporation). This instrument provides stable measurement as an electronic hygrometer,
can be used as a replacement of conventional Assman Aspirated Psychrometer. Assman Aspirated
Psychrometer often reads higher humidity when comparison is made with IAQ Monitor. Handling and
condition, such as wrapping and dust, drastically affect Assman Aspirated Psychrometer, so that such
handling must be done in caution.
For more information on proper handling of your Assman Psychrometer, please fere to the Japanese
Industrial Standard (JIS-Z8806 “Measuring Method for Humidity”).
