Unreferenced date August 2008 A candy thermometer , also known as a sugar thermometer , is a thermometer used to measure the temperature and therefore the stage of a cooking sugar solution. See Candy Sugar stages Candy for a description of sugar stages. These thermometers can also be used to measure hot oil for deep frying . There are several kinds of candy thermometers available. These include traditional liquid thermometers, coil spring dial thermometers and digital thermometers. The digital thermometers tend to read the temperature more quickly and accurately, and some models have an alarm when the thermometer hits a certain temperature. Many models have markers for the various stages of sugar cooking. A candy thermometer is similar to a meat thermometer except that it can read higher temperatures usually 400 F 200 C or more .

File SpiritTherm02.jpg right The Alcohol thermometer or spirit thermometer is an alternative to the mercury in glass thermometer , and functions in a similar way. But unlike mercury in glass thermometer, the contents of an alcohol thermometer are less toxic and will evaporate away fairly quickly. An organic liquid is contained in a glass bulb which is connected to a capillary of the same glass and the end is sealed with an expansion bulb. The space above the liquid is a mixture of nitrogen and the vapour of the liquid. For the working temperature range, the meniscus or interface between the liquid is within the capillary. With increasing temperature, the volume of liquid expands and the meniscus moves up the capillary. The position of the meniscus shows the temperature against an inscribed scale. The liquid used can be pure ethanol or toluene or kerosene or Isoamyl acetate , depending on manufacturer and working temperature range. Since these are transparent , the liquid is made more visible by the addition of a red or blue dye . One half of the glass containing the capillary is usually enamelled white or yellow to give a background for reading the scale. The range of usefulness of the thermometer is set by the boiling point of the liquid used. In the case of the ethanol filled thermometer the upper limit for measurement is 78 C, which makes it useful for measuring day and night time temperatures and to measure body temperature, although not for anything much hotter than these.

Unreferenced date December 2009 image Meat thermometer.jpg thumb A meat thermometer with a dial. Notice the markings for each type of meat A meat thermometer is a thermometer used to measure the internal temperature of meat , especially roasts and steak s, and other cooked foods. The degree of doneness of meat correlates closely with the internal temperature, so that a thermometer reading indicates when it is cooked as desired. Meat should always be cooked so that the interior reaches a temperature sufficient to kill pathogens that may cause foodborne illness the thermometer helps to ensure this. Characteristics A meat thermometer has a metal probe with a sharp point which is pushed into the meat, and a dial or digital display . Some show the temperature only others also have markings to indicate when different kinds of meat are done to a specified degree e.g., beef medium rare . Meat thermometers are usually designed to have the probe in the meat during cooking. Some use a Bi metallic strip Applications bimetallic strip which rotates a needle which shows the temperature on a dial the whole thermometer can be left inside the oven during cooking. Another variety commonly used on Domesticated turkey turkey is the pop up timer, which uses a spring held in by a soft material that pops up when the meat reaches a set temperature.

Unreferenced date March 2009 A recording thermometer is a type of thermometer that records temperature changes over a period of time. The recording thermometer uses a strip that coils and uncoils as the temperature changes. One end of the strip is attached to a long, light metal lever that holds a special pen. Tiny movement of the bimetallic strip causes much larger movement of the free end of the lever and the pen. The pen traces a rising and falling line on a strip of paper attached to a slowly turning drum. The drum usually makes one turn every seven or so days, so afterwards each strip of paper contains a complete and accurate record of temperature changes for a whole week. There are normally two types of metal on the bimetallic strip. Mostly one is steel and one is copper. Due to the different rates of expansion, the strip curves. When it curves, the data is converted into electric signals, which record the temperature change. Category Thermometers tool stub ... more details

Image Rtherm.JPG thumb 250px Unprotected Reversing Thermometer Unlike most conventional mercury element mercury thermometers , a reversing thermometer is able to record a given temperature to be viewed at a later time. If the thermometer is flipped upside down, the current temperature will be shown until it is turned upright again. This was the primary device used by oceanography oceanographers to determine water temperatures below the surface of the ocean from around 1900 to 1970. It consists of a conventional bulb connected to a capillary in which a constriction is placed so that upon reversal the mercury column breaks off in a reproducible manner. The mercury runs down into a smaller bulb at the other end of the capillary, which is graduated to read temperature. A 360 turn in a locally widened portion of the capillary serves as a trap to prevent further addition of mercury if the thermometer is warmed and the mercury expands past the break off point. The remote reading potentialities of reversing thermometers make them particularly suitable for use in measuring subsea temperature as a function of pressure. In this application, both protected thermometers and unprotected thermometers are used, each of which is provided with an auxiliary thermometer. They are generally used in pairs in Nansen bottle s. They are usually read to 0.01 C, and after the proper corrections have been applied, their readings are considered reliable to 0.02 C. ref cite web author Sarah T.

Typical design Suspended in the liquid are a number of weights. Commonly those weights are themselves attached to sealed glass bulbs containing colored liquid for aesthetic effect. As the liquid in the cylinder changes temperature , its density changes and the bulbs are free to move rising or falling to reach a position where their density is either equal to that of the surrounding liquid or where they are brought to a halt by other bulbs.

It stands 134 feet tall, and is capable of displaying a maximum temperature of 134, both of which are a reference to the temperature record. History Approved by San Bernardino County by Planner Nancy Sansonetti, it was built in 1991 by the Young Electric Sign Company of Salt Lake City, Utah Salt Lake City , Utah . Location The world s tallest thermometer is located adjacent to a Bob s Big Boy Restaurant and is visible along Interstate 15 in California Interstate 15 in Southern California s Mojave Desert in Baker. Along the interstate, the landmark is visible from three different sides. Bun Boy restaurant went out of business after several decades of delighting motorists.

Retrieved 07 03 2010. ref Liquid crystals possess the mechanical properties of a liquid, but have the optical properties of a single crystal. Temperature changes can affect the color of a liquid crystal, which makes them useful for temperature measurement. The resolution of liquid crystal sensors is in the 0.1 Celsius C range. Disposable liquid crystal thermometers have been developed for home and medical use. For example if the thermometer is black and it is put onto someone s forehead it will change colour depending on the temperature of the person. There are two stages in the liquid crystals, 1 the hot nematic stage is the closest to the liquid phase where the molecules are freely moving around and only partly ordered. 2 the cold smectic stage is closest to the solid phase where the molecules align themselves into tightly wound chiral matrixes. Liquid crystal thermometers portray temperatures as colors and can be used to follow temperature changes caused by heat flow. They can be used to observe that heat flows by Heat conduction conduction , convection , and radiation . In medical applications, liquid crystal thermometers may be used to read body temperature by placing against the forehead. These are safer than a mercury in glass thermometer , and may be advantageous in some patients, but don t always give an exact result, especially the smaller ones.
