Maximum and minimum thermometer invented by James Six and built by Antonio Matteucci for the Museo di Fisica e Storia Naturale. The figure below shows the operating principle of a gas filled thermometer where the pressure measurement is based on the use of a Bourdon tube. The key difference between regular thermometers and Six's thermometers, besides the ability of the latter to record maximum and minimum temperatures together, is that in regular mercury thermometers it is the expansion of mercury which records the temperature. The reset is carried out by turning the U to the vertical so the markers sink to rest on the mercury, and returning it to the horizontal. To fully understand how to use a hygrometer, it helps to know when and where you can use it.A hygrometer is an essential instrument in meteorological science. • The normal adult body temperature is 37 degrees Celsius. An index rests on top of either end of the mercury columns. The best or most appropriate type of thermometer and where to measure body temperature depends mostly on age. They are ideal for use in the catering trade for hygiene testing, retail outlets, and laboratories. (If the markers are not reset, they will register maxima and minima only if they exceed the values already encountered. A thermometer is a tool to measure temperature. -Thermometer : Are used mostly in industry to measure the temperature of confined gases. The maximum and minimum readings are recorded by two small steel markers which are sprung into the capillary tube so that they can slide, but only if a force is applied to them, either by being pushed by the mercury or under the influence of an external magnet. This is unlike a normal mercury thermometer, in which the expansion and contraction of mercury itself indicates temperature. Six's maximum and minimum thermometer is a popular thermometer among gardeners for use in greenhouses. Like the Thermometer project, this uses the temperature sensor inside the micro:bit’s CPU (central processing unit) to measure the temperature in °C (Celsius).
