   Thermometer
   A thermometer is a device used to measure temperature. It was invented by Galileo in 1592. The graduation and inclusion of fixed points was added by Sanctorio who used snow and the heat of a candle, dividing the range obtained into degrees. The first sealed thermometer was made by Ferdinand II, the Grand Duke of Tuscany, in 1654. He filled the bulb and part of the tube with alcohol and then melted the glass tip, thereby sealing the tube. In England, Boyle, at the request of the Royal Society, ma...

   Thermometer
   An instrument for measuring temperatures. Three different systems are employed. The Fahrenheit scale records freezing point of water at 32 degrees and boiling point at 212 degrees; the Centigrade scale registers freezing point at 0 degrees and boiling point at 100 degrees; the Reaumur scale has a freezing point of 0 degrees and a boiling point of 8...

    Thermometer
    A `thermometer` is a device that measures temperature or temperature gradient, using a variety of different principles. The word thermometer is derived from two smaller word fragments: `thermo` from the Greek for heat and `meter` from Greek, meaning to measure. A thermometer has two important elements, the temperature sensor (e.g. the bulb on a mercury thermometer) in which some physical change occurs with temperature, plus some means of converti...
