CEO Compensation and America's Growing Economic Divide. An alcohol thermometer is a liquid-in-glass thermometer which uses ethyl alcohol to gauge temperatures. Six’s thermometer is used where when one wants to know the maximum or minimum temperature during a day. They are ideal for use in the catering trade for hygiene testing, retail outlets, and laboratories. • The normal adult body temperature is 37 degrees Celsius. One side registers the maximum temperature and the other side records the minimum temperature. The thermometer operates in the same way as the mercury version. Before each reading, the thermometer must be reset with iron indexes being moved back into position at each end of mercury section with the aid of a magnet. This was published posthumously in London, in 1794, a year after he died. Their positions on the maximum and minimum scales show the highest and lowest temperatures encountered since the last reset.[4]. Its purpose is to record the maximum and minimum temperatures reached since the thermometer was last read. [2], In the bend of the U is a section of mercury, a metal which is liquid at normal temperatures. Before a new maximum or minimum reading can be taken, the thermometer must be reset by moving the markers to the top of the mercury, usually by hand using a small magnet to slide them along the tube. It indicates current temperature along with the highest and the lowest temperatures since it was last set.

One of the bulbs is completely filled with alcohol and the other bulb is … -Thermometer : Are used mostly in industry to measure the temperature of confined gases. Any change in temperature after that will push one of the markers along with it. 1. If it falls, the moving mercury will push the minimum scale marker. Six’s Maximum and Minimum thermometer is a U shaped parallel tube made up of glass. They measure temperature using the positive temperature coefficient of electrical resistance of metals. 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. 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. Body temperature is a great indicator of health. Knowing how to use a digital thermometer properly will ensure you are able to take your temperature and see if something is wrong. When a manual control is operated, the plate is pushed away from the U-shaped tube, freeing the markers which then drop under gravity to the surface of the mercury. The arms of the U-shaped tube terminate in sealed glass bulbs. Six's thermometer is used to measure? Generally speaking a minimum temperature occurs during the night and a maximum during the day. It is the alcohol which measures the temperature; the mercury indicates the temperature reading on both scales. Six's thermometers are an excellent way to record both the highest and lowest temperatures in a day without going outside and making note of the temperature repeatedly. Resistance temperature detectors (RTDs) are wire windings or other thin film serpentines that exhibit changes in resistance with changes in temperature. The extremely fine tube (narrow bore) of a thermometer is called a capillary. Wired probes are often more complex with a at least a 1 metre cable and extra features. A Six's thermometer functions by using alcohol to expand or contract the mercury inside to display both the highest and lowest temperatures of a given time period. Log in.
