4. Their positions on the maximum and minimum scales show the highest and lowest temperatures encountered since the last reset.[4]. 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. Tutorvista.com has created a video animation to describe the working of the different types of Thermomenters. Six’s Maximum and Minimum thermometer is a U shaped parallel tube made up of glass. Six's Maximum and Minimum thermometer is a U shaped parallel tube made up of glass. Rights. Cancel Unsubscribe. These are the maximum and minimum temperatures and the current temperature. It is used to record the extremes of temperature at a location, for instance in meteorology and horticulture. Why is the six’s thermometer called minimum and maximum thermometer? The highest number will be the maximum, the lowest the minimum, and the current temperature will be somewhere in between. It measures temperature in increments of one decimal place and is accurate to ±1°C. 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. The arms of the U-shaped tube terminate in sealed glass bulbs. Six's Maximum and Minimum thermometer is a U shaped parallel tube made up of glass. In a variation of design, some models have unsprung markers held in place by a magnetic plate located behind the card showing the scales and close enough to the U-shaped tube to hold the markers in place unless they are pushed by the thermal expansion of the device. This helps in recording the maximum and minimum temperatures of the It is commonly used wherever a simple way is needed to measure the extremes of temperature at a locat ion, for instance in meteorology and horticulture Before a maximum or minimum reading can be taken, both markers must be returned to the top of the mercury, usually by hand using a small magnet to slide them along the tube. One of the bulbs is completely filled with alcohol and the other bulb is … JAMES SIX invented the Maximum and Minimum thermometer in 1782. Meteorological instruments .. Six's maximum and minimum thermometer Mercury barometers Old and morden aneroid barometer Explain the working of ‘Six’s maximum and minimum thermometer’ The thermometer operates in the same way as the mercury version. The bend at the bottom of the thermometer contains mercury which moves up or down based on the expansion and contraction of alcohol. To bring them back into contact with the mercury, they are simply dragged back into the capillary tube by means of a magnet.

It is used to record the extremes of temperature at a location, for instance in meteorology and horticulture. When you record your data from your sixes thermometers you will record three numbers. The bend at the bottom of the thermometer contains mercury which moves up or down based on the expansion and contraction of alcohol. How is a six’s thermometer useful in a green house? Subject: meteorology, Maker: Taylor Instrument Companies (1851 - 1992) Supplier: Andrew J. Lloyd Company (fl. Six's maximum minimum thermometer Six's maximum minimum thermometer. Go to Activity A Stevenson screen or instrument shelter is a shelter or an enclosure to meteorological instruments against precipitation and direct heat radiation from outside sources, while still allowing air to circulate freely around them. 2. The thermometer consists of a U-shaped glass tube with two separate temperature scales set along each arm of the U. Its purpose is to read themaximum and minimum temperatures reached since thethermometer was last read. They move along with the flow of place. with the help of a diagram. It consists of a U-shaped capillary tube with bulbs at both ends. In 2006, S.Brannan & Sons Ltd, a UK company, was granted a patent for a mercury-free version of Six's maximum–minimum thermometer: instead of mercury two immiscible liquids are used supporting an index[clarification needed]. It indicates current temperature along with the highest and the lowest temperatures since it was last set. 54 sold. The markers thus record the furthest point reached by the mercury in each arm of the tube, and thereby the highest and lowest temperatures since the last reset. Temperature Range: -20 to 50°C&F Accuracy: +/-1°C IP Rating: IP 65 Battery: 1 x AAA (Supplied) Product Dimensions: 203 x 100 x 30mm This a very popular and reliable thermometer for monitoring maximum and minimum temperatures. Want a call from us give your mobile number below, For any content/service related issues please contact on this number. Six's maximum and the minimum thermometer is used for measuring the day's maximum and minimum temperature. ), If the temperature rises, the maximum scale marker will be pushed. This is pushed around by the thermal expansion and contraction of the alcohol in the first bulb as it responds to the external temperature. Classification: Thermometer. Generally speaking a minimumtemperature occurs during the night and a maximum during the day. Using this animatited video we can understand the construction and the working of a Six's maximum and minimum thermometer. A maximum-minimum thermometer works by registering the maximum and minimum temperatures over a certain time period by using two scales set in liquid mercury. Six's thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours. 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). MAX MIN THERMOMETER - GARDEN GREENHOUSE INDOOR OUTDOOR WALL - 12/428/3. thermometer is a U shaped parallel tube made up of glass. Why is alcohol used in measuring temperature of very cold countries?
