PROBLEM TO BE SOLVED: To provide a measuring device which can enhance measurement accuracy and perform prompt measurement by simplifying an air intake passage and homogenizing a temperature distribution in a space where a sensor or a sensor sensitive section is installed therein.SOLUTION: A measuring device comprises: a sensor 2 which measures including a temperature and humidity of air with a sensitive section thereof; a case 10 which stores the sensor 2 or the sensitive section thereof; and a fan 5 which introduces the air into the sensor 2 or the sensitive section thereof. The fan 5 has a cylindrical opening section with an impeller mounted therein. The case 10 has a flat plate with a ventilation hole 17d at a bottom section thereof. The fan 5 is fixed to the case 10 in a manner that aligns an inlet side of the cylindrical opening with the ventilation hole 17d. The fan 5 is an axial fan and arranged in a manner that positions an outlet side of the cylindrical opening opposite to the sensor 2 or the sensitive section thereof.SELECTED DRAWING: Figure 3 |
