Abstract
According to the conventional knowledge, a thermal humidity measurement device has problems in which the direction of air flow is limited to one direction is too hard to handle in securing the humidity responsiveness because there are limitations on the mounting direction of the thermal humidity measurement device and the state of air flow.An introduction guide protrudes from an air introduction surface to the outside of a measurement chamber, is parallel to a humidity introduction port surface, and has a portion not in contact with an inlet surface of a humidity introduction tube as seen from any direction to guide the flow of air to the humidity introduction tube from any direction of 360°.
