distinguish hydrometer A Hygrometer IPA en ha r m t UK is an instrument used for measuring the moisture content in the environmental air, or humidity . Humidity is difficult to measure accurately. Most measurement devices usually rely on measurements of some other quantity such as temperature, pressure, mass or a mechanical or electrical change in a substance as moisture is absorbed. From calculations based on physical principles, or especially by calibration with a reference standard, these measured quantities can lead to a measurement of humidity. Modern electronic devices use temperature of condensation, changes in electrical resistance , and changes in electrical capacitance to measure humidity changes. File Haar Hygrometer.jpg thumb Dial Hygrometer, in this case a hair tension style, note nonlinear scale Common Hygrometer Types Metal Pulp Coil type The familiar metal paper coil hygrometer is useful for giving a dial indication of humidity changes, but its accuracy is limited. Humidity is absorbed by a salt impregnated paper strip attached to a metal coil, causing it to change shape.

The dry bulb temperature is the temperature of air measured by a thermometer freely exposed to the air but shielded from radiation and moisture . Dry bulb temperature is the temperature that is usually thought of as air temperature, and it is the true thermodynamic temperature. It is the temperature measured by a regular thermometer exposed to the airstream. Unlike wet bulb temperature , dry bulb temperature does not indicate the amount of moisture in the air. In construction , it is an important consideration when Design designing a building for a certain climate . Nall called it one of the most important climate variables for human comfort and building energy efficiency. ref Nall, D. H. 2004 11 .

Mergeto Hygrometer date December 2008 Dewcels are instruments used for determining the dew point . They consist of a small heating element surrounded by a solution of lithium chloride . As the LiCl absorbs moisture from the air, conduction across the heating element increases, current in it increases, and heat increases, evaporating moisture from the salt solution. At a certain temperature the amount of moisture absorbed by the salt solution equals the amount evaporated equilibrium . Inside the dewcel core a thermistor composite or other temperature measurement device changes electrical resistance with the temperature created by the heating. A front end processor provides a reference voltage , measures the output of the network, and calculates the dew point.

Multiple issues rewrite January 2011 John Coventry 1735 1812 , constructor of philosophical instrument s, was born in Southwark in 1735. He made a position through the care with which his instruments were made. He was the inventor of a new hygrometer , more accurate than any which had been previously in use. This instrument was very generally employed by the chemist s and other scientific men of his day. His telescope s were found to be more accurately adjusted than those usually employed, and the lenses with which they were fitted were more truly ground. His graduations were especially correct. He was a friend of Benjamin Franklin , who appears to have consulted him on questions connected with electrical apparatus . Coventry died in 1812.

for the chambers used in chemistry Desiccator A dry box is a storage container in which the interior is kept at a low level of humidity. Dry boxes are used to safely store items which would otherwise be damaged or adversely affected by excessive humidity , such as Camera cameras and Camera lens lenses to prevent fungal growth , and musical instruments to prevent humidity induced swelling or shrinkage of wooden instrument parts . They are also used in the storage of surface mount electronic components prior to circuit board assembly. Types Desiccant boxes A simple dry box can consist of nothing more than a sealed, airtight box containing a desiccant such as silica gel or anhydrous calcium chloride. These can be easily built at relatively low cost. However, the humidity level in such boxes cannot be controlled or regulated owing to the difficulty of gauging the quantity of desiccant required to achieve a certain humidity level. Electronic dry boxes Electronic dry boxes contain a small Thermoelectric cooling peltier cooler , which remove moisture from the air by condensing it out. A control dial is usually provided which permits the user rough adjustment of the humidity level. More sophisticated designs link the cooler to a settable digital hygrometer, allowing very precise humidity level control.

Image weather house.jpg thumb A weather house is depicted on this New Year s Day greeting card by the Czech Republic Czech artist Tavik Frantisek Simon . A weather house is a folk art device in the shape of a small Germany German or Alps Alpine chalet that indicates the weather . A typical weather house has two doors side by side. The left side has a girl or woman, the right side a boy or man. The female figure comes out of the house when the weather is sunny and dry, while the male comes out to indicate rain . In fact, a weather house functions as a hygrometer embellished by folk art. The male and female figures ride on a balance bar, which is suspended by a piece of catgut or hair. The gut relaxes or shrinks based on the humidity in the surrounding air, relaxing when the air is wet and tensing when the air is dry. This action swings one figure or the other out of the house depending on the humidity. ref http www.rmets.org education weatherclub primary houses.php Weather houses at the Royal Meteorological Society ref Weather houses are associated in the popular mind with Germany or Switzerland , and are often decorated in the style of a cuckoo clock . Many weather houses also bear a small thermometer on the part between the two doors that conceals the gut suspension, and many also contain a piggy bank . Cultural influence A one act English comic opera called Weather or No , about the male and female figures in a weather house falling in love, became popular when it was played as a companion piece to The Mikado in 1896 97.

orphan date September 2010 Unreferenced date September 2009 Ren Grillet de Roven , also Ren Grilliet , was a French mechanic and watchmaker who designed a mechanical calculating machine in the 17th century. Biography Grillet came from Rouen in northwestern France, the capital city of Normandy . He served as watchmaker to King Louis XIV . In 1673 Grillet published a small book, Curiositez mathematiques de l invention du Sr Grillet horlogeur a Paris , in which he announced the invention of an arithmetical calculating machine. A few years later, in 1678, he wrote a short article in Le Journal des S avans describing the machine. According to Grillet, he was inspired by Blaise Pascal s work with calculating machines to combine the Pascaline with Napier s bones , and build a machine that could perform both addition and multiplication. Grillet displayed his machine at fairs in France and the Netherlands between 1673 and 1681. He tried to establish a business of manufacturing and selling calculating machines, with unclear success. In addition to the calculating machine, in his career Grillet invented a hygrometer for which he was accused of plagiarism by another inventor graphometer s drawing instrument set protractor , set square , with plumb bob . In 1690, the first textile printing factory in England was established by a Frenchman named Ren Grillet, who took out a patent on the process.

Ernst Friedrich Wilhelm Klinkerfues 29 March 1827 &ndash 28 January 1884 was a German astronomer . Life Klinkerfues was born in Hofgeismar , the son of army doctor Johann Reinhard Klinkerfues and his wife Sabine. After the early death of his parents, he was brought up by relatives, and after attending high school qualified as a surveyor in Kassel . In this capacity he subsequently worked on the new Frankfurt Kassel railway. From 1847 to 1851 Klinkerfues studied mathematics and astronomy at the University of Marburg . He then became an assistant to Carl Friedrich Gauss at G ttingen Observatory , where he completed his Ph.D. with a thesis on orbit calculations of double stars . After Gauss death in 1855, the mathematician W. E. Weber replaced him as director, but Klinkerfues was to be temporarily responsible for the observatory from 1861. Klinkerfues discovered 6 comets, and in 1860 led an expedition to Spain to observe a solar eclipse . He was finally appointed director for practical astronomy at G ttingen in 1868. However, the role of Klinkerfues section of the observatory was solely to deal with practical work, the theoretical work being placed in the hands of Ernst Schering . Klinkerfues was, like his predecessor, allowed to live in the eastern wing of the observatory, but the division of the observatory s organisation between the two teams was to be a source of constant conflict. In his 1871 book Theoretische Astronomie Klinkerfues described how the orbits of celestial bodies in the solar system could be calculated. In the same period he compiled a catalogue of around 6900 observed stars. Klinkerfues also had an abiding interest in meteorology , developing a hygrometer , patented in 1877, that was later manufactured in G ttingen by Wilhelm Lambrecht. His weather forecasts, published in newspapers, proved to be often incorrect, which led to them cruelly parodying his last name as Flunkerkies . Undeterred by this criticism, he published a book on the hygrometer s u ... more details

They are silvery grey with dark brown to black spots, and derive their name from bright red coloring on the ventral side of their hind legs. Adult body length is typically 6 to 7.5 centimeters. Other common names include brown spotted tree frog, red legged Kassina, red legged pan frog, spotted running frog, tiger leg running frog , and vlei frog . Habitat K. maculata is endemic to the tropical and sub tropical areas of Africa s east coast Kenya , Malawi , Mozambique , South Africa , Swaziland , Tanzania , and Zimbabwe . The frog thrives in varying terrain including shrubland, grassland, savannah, and forest as long as there exists a ready source of fresh water or high humidity. Behavior Red legged running frogs are nocturnal, and therefore somewhat elusive to humans preferring to burrow under loose soil or vegetation during the day. At night they take to climbing trees and tall shrubs to feed mainly on a diet of insects and insect larvae. As Pets Because they are nocturnal and do require a significantly moist environment 80 relative humidity is recommended , they are not as common a pet as other species of frog. However, being rather hardy and robust, they do survive well under appropriate basic conditions. A source of UV light is not required, and ambient temperature of 72 to 77 F 22 to 25 C is sufficient. Both a thermometer and hygrometer should be present. Moss or coconut fiber should be used as substrate for burrowing, with both wet and dry ground areas within the enclosure. A basin or bowl of clean, fresh water is necessary. Misting of fresh water should occ ... more details

Goldbeater s skin the outer membrane of calf s intestine is a parchment traditionally used in the process of making gold leaf by beating reducing gold into mere 1 m thick leaves. Up to 120 sheets of gold laminated with goldbeater s skin can be beaten at the same time, since the skin is thin, elastic and does not tear under heavy goldbeating . To manufacture goldbeater s skin, the gut of oxen or other cattle is soaked in a dilute solution of potassium hydroxide , washed, stretched, beaten flat and thin, and treated chemically to prevent putrefaction . A pack of 1,000 pieces of goldbeater s skin requires the gut of about 400 oxen, and is only 1 inch thick. Uses Goldbeater s skin is used as the sensitive element in hygrometer s, since, due to its hygroscopy hygroscopic property, variations in atmospheric humidity cause skin contraction or expansion. Alexander Graham Bell used a drum of goldbeater s skin with an armature of magnetised iron attached to its middle as a sound receiver see Invention of the telephone and the North German Confederation printed 10 and 30 groschen postage stamp s on goldbeater s skin, to prevent reuse of these high value stamps. Joseph Thomas Clover invented an apparatus for the inhalation of chloroform in 1862. This consisted of a large reservoir bag lined with goldbeater s skin to make it airtight, into which a known volume of liquid chloroform was injected. ref Sykes WS 1960 . Essays on the First Hundred Years of Anaesthesia , Vol. 2, Churchill Livingstone, Edinburgh.
