The present invention provides an apparatus that is used to measure relative humidity, such apparatus comprises a housing having a first end and a second end. There is a humidity sensor disposed at the first end of the housing for measuring the humidity in the air and a temperature sensor also disposed at the first end of the housing for measuring ambient temperature. The apparatus has an electronics portion in direct electrical communication with the humidity sensor and the temperature sensor for computing a relative humidity and a dewpoint temperature. The electronics portion is disposed within a center portion of the housing. There is, further, a battery that is in electrical communication with the electronics portion, the humidity sensor and the temperature sensor for providing power to the apparatus. Such battery is disposed in the center portion of the housing of the apparatus. The apparatus has a display means that is in electrical communication with the electronics portion and with the battery for displaying such relative humidity and such dew point temperature as determined by the electronics portion. The display means is disposed at a second end of said housing.
