Liquid-In-Glass Thermometers Liquid-In-Glass Thermometers. A liquid-in-glass thermometer is the simplest and most commonly employed type of temperature measurement device. It is one of the oldest thermometers available in the industry. It gives fairly accurate results within the temperature range of -200 to 600°C. No special means are needed to measure temperature via these thermometers.

Mercury-in-glass thermometer Mercury-in-glass thermometer for measurement of room temperature. The mercury-in-glass or mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit in Amsterdam (1714). It consists of a bulb containing mercury attached to a glass tube of narrow diameter; the volume of mercury in the tube is much less than the volume of the bulb.

- 3.1.3 Controls It is possible to use the glass tube thermometer to create a control element. By placing a conductive element inside the glass tube, such that the mercury touches it at the desired operating point, and a second contact in the mercury at the bottom, you can create an electrical switch.

Mercury-in-glass thermometer The mercury-in-glass or mercury thermometer was invented by Polish-Dutch physicist Daniel Gabriel Fahrenheit in Amsterdam (1714). It consists of a bulb containing mercury attached to a glass tube of narrow diameter; the volume of mercury in the tube is much less than the volume of the bulb. The volume of mercury changes slightly with temperature; the small change in volume drives the narrow mercury column a relatively long way up the tube.

- The master is the most accurate and repeatable thermometer you can afford. The 'slave' is a cheaper thermometer, repeatedly checked against the 'master'. In fact, we use two 'masters', a pair of mercury-in-glass Brannan laboratory thermometers accurate to 0.1 degrees C by interpolation, or 0.2 degrees on the scale.he master is the most accurate and repeatable thermometer you can afford.

Mercury-in-glass thermometer A special kind of mercury-in-glass thermometer, called a maximum thermometer, works by having a constriction in the neck close to the bulb. As the temperature rises, the mercury is pushed up through the constriction by the force of expansion.

- Galileo thermometer. A Galilean thermometer. A Galileo thermometer (or Galilean thermometer) is a thermometer made of a sealed glass cylinder containing a clear liquid and several glass vessels of varying densities. As the temperature changes, the individual floats rise or fall in proportion to their respective density.

- The Liquid in Glass thermometer utilizes the variation in volume of a liquid in temperature. They. use the fact that most fluids expand on heating. The fluid is contained in a sealed glass bulb, and. its expansion is measured using a scale etched in the stem of the thermometer If we consider that.

Physics Theory : Thermometers These temperatures are typically used in the calibration of thermometers and are known as the fixed points. The temperature range that is typically marked on a laboratory thermometer is −10oC to 110oC. Thermometric liquids are those that are used in thermometers. Some examples of such liquids are mercury and alcohol.
