The Taylor Oven Thermometer is made of sleek, durable stainless steel and has a large display with a bright red pointer designed for better visibility. It takes temperatures ranging from 100-600 ...
A recording thermometer is a type of thermometer that records temperature changes over a period of time. A digital recording thermometer is often called a temperature data logger . Analog temperature recorders
An example of a reference thermometer used to check others to industrial standards would be a platinum resistance thermometer with a digital display to 0.1 °C (its precision) which has been calibrated at 5 points against national standards (−18, 0, 40, 70, 100 °C) and which is certified to an accuracy of ±0.2 °C.

An infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called black-body radiation emitted by the object being measured. They are sometimes called laser thermometers as a laser is used to help aim the thermometer, or non-contact thermometers or temperature guns , to describe the ...
A medical mercury-in-glass maximum thermometer showing the temperature of 38.7 °C (101.7 °F). One 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.
A Beckmann thermometer is a device used to measure small differences of temperature, but not absolute temperature values. It was invented by Ernst Otto Beckmann (1853 – 1923), a German chemist , for his measurements of colligative properties in 1905. [ 1 ]
A Celsius Galilean thermometer in two degree gradations. A risen orange orb denotes 24 °C. 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 density. The individual floats rise or fall in proportion to their respective density and the ...
Ethanol-filled thermometer are used in preference to mercury for meteorological measurements of minimum temperatures and can be used down to −70 °C (−94 °F). [2] The physical limitation of the ability of a thermometer to measure low temperature is the freezing point of the liquid used. Ethanol freezes at −114.9 °C (−174.82 °F).
