Thermometers measure temperature, by using materials that change in some way when they are heated or cooled. In a mercury or alcohol thermometer the liquid expands as it is heated and contracts when it is cooled, so the length of the liquid column is longer or shorter depending on the temperature.
Thermometers A thermometer is a device or instrument used for measuring temperature. There are many different types of thermometers; however each one is based on a physical property of a thermometric (temperature measuring) substance that differs in a measurable way with temperature.
A thermometer is a device or instrument used for measuring temperature. There are many different types of thermometers; however each one is based on a physical property of a thermometric (temperature measuring) substance that differs in a measurable way with temperature.The basic objective of this project was to build an audible thermometer, which will be very useful for persons with vision problems and blinds, who cannot read the numbers shown on the modern digital thermometers. The human error is very common. A little distraction can make us note down 85oC as 58oC. This is very common with us.A thermometer can be mercury, liquid-in-glass, electronic with digital display, infrared or tympanic, or disposable dot-matrix. It can be used in a clinical or emergency setting or at home. They do give you a pretty good idea of a person’s temperature though. Thermometers are vey helpful to Americans today.
Gas thermometer A gas thermometer measures temperature by the variation in volume or pressure of a gas. One common apparatus is a constant volume thermometer. It consists of a bulb connected by a capillary tube to a manometer. The bulb is filled with a gas such that the volume of the gas in the bulb remains constant.Read More
A thermometer is an instrument we can use to measure temperature. An analog thermometer consists of a sealed tube with markings on it. These markings are increasing temperatures in Celsius or Fahrenheit. The markings on a clinical and weather thermometer are different, but they work in the same way.Read More
A thermometer is an instrument for measuring or showing temperature (how hot or cold something is). One type of thermometer is a narrow, concealed glass tube containing mercury or alcohol which extends along the tube as it expands. Another type is a digital thermometer, which uses electronics to measure temperature. Early thermometers from the time of Galileo measured the expansion and.Read More
A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object). A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this.Read More
Thermometer 5. Wet and Dry Bulb Thermometer 6. Wind Vane 7. Anemometer 8. Rain-Gauge. 1. Barometer: The atmospheric pressure is measured with the help of a barometer. There are two types of barometer—Mercurial and Aneroid. The mercurial barometer—Fortin’s type holds a column of mercury which balances weight of the air. The aneroid type is a vacuum box which measures the atmospheric.Read More
The alcohol or mercury thermometer that are vastly used in the medical world today would not have existed had it not been for Galileo Galilei. Galileo Galilei invented the first thermometer by using the concept of air expansion by heat and contraction by cold. Only after that, other scientists came up with a more developed and accurate thermometer. One of them being Sir Isaac Newton. Years.Read More

A medical thermometer (also called clinical thermometer) is used for measuring human or animal body temperature.The tip of the thermometer is inserted into the mouth under the tongue (oral or sub-lingual temperature), under the armpit (axillary temperature), into the rectum via the anus (rectal temperature), into the ear (tympanic temperature), or on the forehead (temporal temperature.Read More
A clinical thermometer is a thermometer used to measure human body temperature. Most made in the 20th century are mercury-in-glass thermometers. They are accurate and sensitive, having a narrow place where the mercury level rises very fast. A kink in the tube stops the mercury level from falling on its own. These thermometers are used in clinics by doctors, so they are also called a doctor's.Read More
