Abstract
A hand held testing surface and scale card may be used in conjunction with a radiation detector to obtain an indication of relative humidity. The scale card is provided with two sections. One section is of absorbent relatively thin material; the second section is of non-absorbent material. The absorbent section is wetted by the user just prior to detection and cooled by evaporation. A radiation detector is then able to sense a wet bulb temperature from the wetted and cooled absorbent section. The section of non-absorbent material is kept dry. From this dry section, the radiation detector senses a dry bulb temperature. Using the sensed wet bulb and dry bulb temperatures, the user calculates the relative humidity and dew point temperature from the scales provided on the card.
