psychrometer

 [si-krom´ĕ-ter]
an instrument for measuring the moisture of the atmosphere.

psy·chrom·e·ter

(sī-krom'ĕ-tĕr),
A device for measuring the humidity of the atmosphere by the difference in temperature between two thermometers, the bulb of one kept moist, the other dry. Evaporation from the moist bulb lowers the reading of that thermometer; the greater the difference in readings, the drier the air is; no difference indicates 100% relative humidity.
[psychro- + G. metron, measure]

psychrometer

[sīkrom′ətər]
an instrument for calculating the degree of humidity in the atmosphere by comparing the temperatures of two thermometers, one with a wet bulb, one dry. The difference in temperature between the two thermometers indicates the relative humidity.
