An instrument used to measure the water vapor content of the air.
an instrument used to measure humidity or moisture content in the air
Device that measures the relative humidity of the air.
An invaluable device that measures the humidity level in a humidor and reminds cigar smokers to top up the water supply on a regular basis.
An instrument designed to measure absolute and relative humidity of the atmosphere.
A sensor that measures dew point.
A mechanical indicator that displays the relative humidity of a space. Traditional non-electronic analog hygrometers are generally accurate to about 10% while electronic digital versions are accurate to less than 5%. Vigilant hygrometers are accurate to 2%.
A meter or device that measures the humidity of the air.
An instrument for directly indicating humidity. hygrometry Any process for determining the amount of moisture present in air or another gas.

a weather instrument used to measure atmospheric water content, or humidity
Any of several instruments used for measuring atmospheric humidity. Some types of hygrometers are: 1) psychrometer - measures the temperature difference between a wet-bulb and a dry-bulb thermometer. A sling psychrometer is mounted in a frame, then whirled in the air for ventilation. 2) hair hygrometer - measures the expansion and contraction of a human hair that is mounted under tension. A gold beater's skin hygrometer uses a proteinaceous membrane for the same type of measurement. 3) dew-point hygrometer - measures the temperature for the formation and evaporation of dew that is observed using a photoelectric cell. 4) diffusion hygrometer - measures the diffusion of water vapor through a porous membrane. 5) lithium chloride hygrometer - measures the temperature and electrical conductivity of a hygroscopic salt that becomes conductive when it absorbs water. - from Boston MFA Conservation and Art Materials Dictionary http://www.mfa.org/conservation/qsearch.htm (May 3, 2001)
Device that measures humidity. Generally speaking the ones on the market measure "relative" humidity. A crabs habitat should ideally have a relative humidity of 70-80%.
An instrument used to measure the amount of moisture in the air.
An instrument that measures moisture in the air. It's also known as a psychrometer.
an instrument used to measure the relative humidity
A device used for exact (?) measurements of relative humidity.
instrument used to measure the relative humidity in the atmosphere
An instrument designed to measure the air's water vapor content.
A tool for measuring the humidity of the air. It is not unheard-of for people to say "hygrometer" when they mean " hydrometer".
an instrument for measuring the water vapor content of the atmosphere
The generic term for instrument that measures humidity. A specific type of hygrometer is a psychrometer. It consists of two thermometers, one wet bulb, one dry bulb. The wet bulb cools in relation to the moisture in the air.
Any instrument for measuring humidity.
A device that indicates the humidity, or percentage of moisture in the air; used to monitor humidor conditions.
An instrument used for measuring dew points of gases.
A device used to measure the relative humidity of the air.
Instrument for measuring relative humidity in the atmosphere: A hygrometer will save time, frustration and money.
An instrument for measuring humidity.
An instrument that responds to humidity conditions (usually relative humidity) of the atmosphere.
a meter for measuring the relative humidity in the air.
Any instrument that measures the water vapor content of the atmosphere. There are six basically different means of transduction used in measuring this quantity and hence an equal number of types of hygrometers. These are 1) the psychrometer, which utilizes the thermodynamic method; 2) the class of instruments that depends upon a change of physical dimensions due to the absorption of moisture ( see hair hygrometer, torsion hygrometer, goldbeater's-skin hygrometer); 3) those that depend upon condensation of moisture ( see dewpoint hygrometer, frost point hygrometer); 4) the class of instruments that depend upon the change of chemical or electrical properties due to the absorption of moisture ( see absorption hygrometer, electrical hygrometer, carbon-film hygrometer element, dew cell); 5) the class of instruments that depend upon the diffusion of water vapor through a porous membrane ( see diffusion hygrometer); and 6) the class of instruments that depend upon measurements of the absorption spectra of water vapor ( see spectral hygrometer).

Hygrometers are instruments used for measuring humidity. A simple form of a hygrometer is specifically known as a "psychrometer" and consists of two thermometers, one of which includes a dry bulb and the other of which includes a bulb that is kept wet to measure wet-bulb temperature. Evaporation from the wet bulb lowers the temperature, so that the wet-bulb thermometer usually shows a lower temperature than that of the dry-bulb thermometer, which measures dry-bulb temperature.
