The river city renaissance water barometer is a historic piece of art that quickly indicates changes in barometric pressure. the ...barometer is composed of antique wood spools found in abandoned textile mills in england. the spools were used to hold thread, cotton, and yarn that were spun into fabric. the spindles and wooden base date back to 1907-1913 and were used in a factory in calder valley, yorkshire which wove the thread into a cotton tartan fabric. each barometer has a cotton sticker from 1917 placed on its base. these stickers were made in new york in 1917 and found in a cupboard with the original invoice. history of the barometer renaissance scientist, evangelista torricelli (1608-1647), discovered the first barometer, proving that air pressure was subject to change. it is believed that goethe, the famous german playwright, developed this simple but effective barometer using the principles established by torricelli. how does it work? the weather ball quickly indicates any changes in atmospheric pressure. the air trapped by the liquid maintains a steady pressure. when high pressure and good weather are approaching, the liquid is pushed down the spout. when low pressure and bad weather invade your region greater pressure trapped inside the weather ball causes the liquid in the spout to rise. if liquid spills out of the top you should take shelter! the glass barometer is made from mouth-blown glass in the united kingdom. as with all antique and hand-made items, the colors and decorations vary slightly. we consider this to be a special part of their history and character. read more

The River City Swan Barometer quickly indicates any changes in atmospheric pressure. The air trapped by the liquid maintains a st...eady pressure. When high pressure and good weather are approaching, the liquid is pushed down the neck of the swan. When low pressure and bad weather invade your region, greater pressure trapped inside the swan causes the liquid in the neck to rise. If liquid spills into the beak of the swan then prepare for fowl weather! Food coloring is not included. This barometer is made with hand-blown glass and is covered by a two year limited warranty covering workmanship and manufacturers defects. read more

As the temperature of the air outside the thermometer changes, so does the temperature of the water surrounding the bubbles. As th...e temperature of the water changes, it either expands or contracts, thereby changing its density. So, at any given density, some of the bubbles will float and others will sink. The bubble that sinks the most indicates the approximate current temperature.<br><br> The rich, solid wood framed cherry weather station with lacquer finish measures barometric pressure (in mbar and inHg) and humidity (%). The barometer allows for sea-level calibration up to 3,000 feet.<br><br> <b>Note: Barometer only operates to about 3.000'.

The bubbles are calibrated by adding a certain amount of fluid to them so that they have the exact same density. So, after the wei...ghted tags are attached to the bubbles, each differs very slightly in density (the ratio of mass to volume) from the other bubbles, and the density of all of them is very close to the density of the surrounding water.<br><br> As the temperature of the air outside the thermometer changes, so does the temperature of the water surrounding the bubbles. As the temperature of the water changes, it either expands or contracts, thereby changing its density. So, at any given density, some of the bubbles will float and others will sink. The bubble that sinks the most indicates the approximate current temperature. The barometer allows for sea-level calibration up to 3,000 feet.<br><br> <b>Size:</b> <br> Thermometer diameter: 1.4 in.<br> Instrument diameter: 2.75 in<br> Overall Height: 11.8 in<br> <b>Details:</b><br> Number of glass balls: 5<br> Characteristic of glass balls: Sliver plated balls<br> <b>The barometer allows for sea-level calibration up to 3,000 feet.</b>. read more

This state-of-the-art collection is waterproof and functions extremely well in the punishing saltwater environment. The low glare ...satin black case of each precision instrument is constructed of solid aluminum that is color anodized and sealed so that the finish will not peel bubble or tarnish. The glass crystal sits in a double O-ring seat for vibration impact and thermal expansion protection. The anodized aluminum dial is laser engraved. The durable moveable markers are made of U.V. stabilized polycarbonate outside the crystal for marking time or pressure. All fasteners are stainless steel. Both the clock and barometer can be purchased with or without the optional incorporated fluid dampened inclinometer. To calibrate the movement in either the clock or barometer twist the case 1/8 turn to remove the case and leave the back plate on the bulkhead. This feature is also convenient should you want to remove your instruments for storage or anti-theft reasons. Hydrophobic filter allows air to pass yet resists water. The filter will easily stop the entrance of water due to continuous spray and because of its unique construction it is waterproof to a depth of 3 feet for 30 minutes. It includes a patented (high sensitive) all metal aneroid movement and has an expanded scale so that the needle noticeably moves as weather conditions change. The scale ranges from 28.5 to 31.5 instead of the traditional 27.5 to 31.5 Hg. It also can be read in millibars. Dial: 3-3/4 . Base: 5-7/8 . Depth: read more

<div class="aplus"><p>The Thomas Traceable hygrometer/thermometer/barometer/dew point pen is a thermometer, humidity gauge, and ba...rometer for measuring air temperature, humidity, dew-point temperature, and air pressure. The thermometer measures temperature from 0 to 50 degrees C (30 to 122 degrees F), with an accuracy of + or - 1 degree C. The humidity meter measures humidity from 10 to 95% relative humidity (RH), with an accuracy of + or - 3% mid-range. The dew-point thermometer indicates dew point from -25.3 to 48.9 degrees C (13.5 to 120.1 degrees F). The barometer measures pressure from 0.29 to 32.48 inches of Mercury (inHg), from 10 to 1100 millibars (hPa), and from 7.5 to 825 millimeters of Mercury (mmHg), with an accuracy of + or - 2.5 hPa. The dual display shows humidity/temperature, humidity/dew point, barometer/temperature, or barometer/humidity. A hold button freezes the reading on the display and the unit's memory holds a minimum/maximum reading. The thermometer is traceable to National Institute of Standards and Technology standards, indicating that it is calibrated to International Organization for Standardization (ISO) 17025 levels. This Thomas thermometer is used to monitor air temperature in laboratories, storage rooms, and refrigerators.</p><h4>Specifications</h4><TABLE BORDER=1 WIDTH="800" CELLPADDING=2><TR BGCOLOR="#dfe1e0"><TD>Power source</TD><TD>(4) AAA batteries</TD></TR><TR><TD>Temperature range</TD><TD>0 to 50 degrees C (30 to 122 degrees F)</TD></TR><TR BGCOLOR="#dfe1e0"><TD>Temperature accuracy</TD><TD>+ or - 1 degree C</TD></TR><TR><TD>Temperature resolution</TD><TD>0.1 degree C/0.1 degree F</TD></TR><TR BGCOLOR="#dfe1e0"><TD>Dew-point temperature range</TD><TD>-25.3 to 48.9 degrees C (13.5 to 120.1 degrees F)</TD></TR><TR><TD>Relative humidity range</TD><TD>10 to 95% RH</TD></TR><TR BGCOLOR="#dfe1e0"><TD>Relative humidity accuracy</TD><TD>+ or - 3% mid-range; + or - 4% outside</TD></TR><TR><TD>Barometric pressure range</TD><TD>0.29 to 32.48 inHg / 10 to 1100hPa / 7.5 to 825mmHg</TD></TR><TR BGCOLOR="#dfe1e0"><TD>Barometric accuracy</TD><TD>+ or - 2.5hPa</TD></TR><TR><TD>Standard met</TD><TD>International Organization for Standardization (ISO) 17025</TD></TR><TR BGCOLOR="#dfe1e0"><TD>Weight</TD><TD>5 oz.</TD></TR><TR><TD>Dimensions (H x W x D)</TD><TD>8 x 1.5 x 1.5 inches</TD></TR></TABLE><br/><p>H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.</p><p>Digital thermometers are instruments used to measure the temperature of air, liquids, or surfaces electronically.
