MEDICAL THERMOMETER Medical thermometers are used for measuring human body temperature‚ with the tip of the thermometer being inserted either into the mouth under the tongue (oral or sub-lingual temperature)‚ under the armpit (axillary temperature)‚ or into the rectum via the anus (rectal temperature). CLASSIFICATION BY TECHNOLOGY Liquid-filled The traditional thermometer is a glass tube with a bulb at one end containing a liquid which expands in a uniform manner with temperature. The tube

The first modern thermometer‚ a mercury thermometer with a standardized scale‚ was invented in 1714 by Daniel Gabriel Fahrenheit‚ a German physicist who also invented the alcohol thermometer in 1709 and the mercury thermometer in 1714. Before Fahrenheit‚ Galileo Galilei and Santorio Santorio both created their own type of thermometers but both of their instruments could not measure the exact temperature. It only indicated temperature differences which classified their instruments a thermoscope. In

Ergonomics of Medical Thermometer In partial fulfillment of BS Industrial Engineering Presented by: Ares Evangelista David Cheysser Layno Lean Lester Goopio Introduction Of the many tools and instruments regarded as essential to the clinical examination‚ none has had such widespread application as the clinical thermometer. In the time of Hippocrates‚ only the hand was used to detect the heat or cold of the human body‚ although fever and chills were known as signs of morbid processes

Homemade Thermometer In middle school your child will be learning all about heat energy and temperature measurement‚ and will likely get to use a lab thermometer. This project will enable your child to construct a homemade thermometer that will compliment what he’s learning about this instrument in school. What You Need: * Tap water * Rubbing alcohol * 11-ounce clear‚ narrow-necked plastic bottle * Red food coloring * Clear plastic drinking straw * Modeling clay *

How Does the Thermometer Work? A thermometer is a device that measures the temperature of things. The name is made up of two smaller words: "Thermo" means heat and "meter" means to measure. You can use a thermometer to tell the temperature outside or inside your house‚ inside your oven‚ even the temperature of your body if you’re sick. One of the earliest inventors of a thermometer was probably Galileo. We know him more for his studies about the solar system and his "revolutionary" theory

MERCURIAL THERMOMETER The principle of the mercurial thermometer is that mercury when heated expands more than glass. If‚ therefore‚ a glass-tube having a bulb blown at one end be partially rilled with mercury and immersed in a bath at a higher temperature than its own‚ the mercury will rise in the tube. If the bath have a lower temperature‚ the mercury will fall. If the mercury neither rise nor fall we may fairly conclude that the mercury and the bath are each at the same temperature. The essential

HOW TO READ YOUR PALM PRINT Have you ever heard that we can know some of our physical and mental condition just through reading our palm prints? (Chinese student: So did your parents bring you to any master to analyze your palm print when you just a little kids?) However‚ my mother took me to find a people so-called master and to read my palm print. First‚ I didn’t believe it because it is sounds ridiculous that you can know your body just through reading your palm prints especially as the
