• relative humidity .
• Relative humidity is the ratio of the current vapor pressure of water in any gas (especially air) to the vapor pressure at which the gas would become saturated at the current temperature, normally expressed as a percentage. ...
• The numerators of these ratios are the two ways of expressing absolute humidity. The following graph compares dew point (maximum humidity in red) to 50% relative humidity (green line halfway between zero and the dew point across the range of temperatures).
• This explains the restriction of relative-humidity discussions to 100% and below. ...
• (The statement that relative humidity can never be above 100%, while a fairly good guide, is not absolutely accurate, without a more sophisticated definition of humidity than the one given here. ...
• For a given dewpoint and its corresponding absolute humidity, the relative humidity will change inversely with the temperature. ...
• This explains the low levels (in the absence of measures to add moisture) of humidity in heated structures during winter, reflected by dry skin, itchy eyes, and persistence of static electric charges. Even with saturation (100% humidity) outdoors, heating of whatever outside air comes indoors raises its moisture capacity, reflected in decreased relative humidity and increased evaporation rates from moist surfaces.

• HUMIDITY.
• - - HUMIDITY - - .
• Humidity is moisture that is suspended in the air. ... Because of this, more moisture needs to be added to maintain the desired level of humidity. ... Humidity can be measured using a simple instrument called a hygrometer. ...
• Keeping the humidity high reduces the speed of water loss (dehydration). Orchids prefer a location where there is a range of humidity between 40% and 70%. ...
• You should not try and keep your humidity at the same percentage all the time. A fluctuation of humidity is desirable and gives the plants a chance to "dry out. ...
• - - CONTROLLING HUMIDITY - - .
• Raising humidity .
• In a greenhouse, you can wet down the walks and floors to increase the humidity. ...
• In your home, a humidity tray works very well. A humidity tray is any kind of shallow container that will hold water. ... For more information about humidity trays, please read my Frequently Asked Questions page. ...

• Humitran-RHT Series - Humidity and Temperature Transmitters.
• DESCRIPTION: TEGAM's solution for monitoring relative humidity and temperature, the RHT series provides a linearized output current from 4-20 mA(model RHT-20C) or a linearized output voltage from 0-1VDC (model RHT-10V) representing temperature and humidity. Humidity readings are temperature compensated and the RHT transmitters only require an unregulated DC supply voltage of 6-30VDC.
• Model RHT-20C produces 4-20 mA current signals representative of temperature and humidity and is ideal for transmitting readings over long distances of cable. ...
• Model RHT-10V produces a linear voltage from 0 to 1 volt representative of temperature and humidity. ...

• Humitran-RH Series - Relative Humidity Transmitters.
• DESCRIPTION: TEGAM's RH series transmitters are an economical solution for the continuous monitoring of relative humidity. ...
• Model RH-10V outputs a 0-1V voltage representative of the humidity for low power or battery powered applications. ...
• Model RH-10V - output 0-1V for 0-100% humidity.
• Model RH-20C - output 4-20mA for 0-100% humidity.
• APPLICATIONS: general purpose monitoring of humidity in storage facilities, test chambers, food processing, medical, grain silos etc.

• Understanding humidity.
• Humidity is the amount of water vapor in the air and can be described in different ways.
• The term that you'll hear most often to describe the humidity is "relative humidity. " This also happens to be, in my opinion, the measurement of humidity that's hardest to understand. ...
• Another common measurement of humidity is the "dew point," which most of us also also have to work, at least a little, to understand. ...
• Unless you are a weather forecaster, or a scientist or engineer involved in work involving the amount of water vapor in the air, you can easily go through life without understanding "relative humidity. ...
• These and other terms used to in relation to humidity are defined at the bottom of this page. ... com Getting a handle on humidity page. ...
• Why humidity is worth worrying about.
• The humidity combined with hot temperatures makes the heat more dangerous. (Related: The dangers of heat and humidity) .
• Indoor, as well as outdoor humidity is important, and humidity that's too high or too low can be dangerous for both you and your house. (Related story: Humidity inside your home) .
• Humidity is a key player in the weather.
• If Earth's air didn't contain as much humidity as it does, our weather would be like that of Mars: No clouds (except dust), no rain, sleet or snow, no thunder and lighting, no fog. ...
• Humidity can be less than 100% when it's raining .
