1.2 Effect of temperature differences in humidity
measurements
In humidity measurement and especially in calibration, it is essential that the temperature of
the probe and the measurement environment are the same. Even a small temperature
differ
ence between the environment and the probe causes an error.
A temperature
differ
ence of a few degrees can also cause water to condense on the sensor
surface. The HUMICAP
â
sensor starts to function normally as soon as the water has
evaporated. If the condensed water is contaminated, the life span of the probe may shorten
and calibration may change.
