What does a max min thermometer do?
Mercury expands on heating.so at noon when the sun is overhead in the thermometer the Mercury expands and pushes the index down.And then the alcohol which is half filled in the maximum tube rises.then the max.temp is taken.
How do you reset a mercury Barometer after travel?
one can use a magnet to push down the indexes and reset it
How do you change Fahrenheit to celsius on mr slim remote?
to change Fahrenheit to celsius on mr slim remote: wile pressing reset press temps up and temps down at the same time then let go of the up and down temps first then the reset.
Why does your well water stop flowing?
Not likely to be a blockage unless it is in the pressure hose to the pressure switch. The pumps usually have a 15 minute cool down reset.
What is the purpose of the rain gauge?
The purpose of the rain gauge is simple, to meausre how much rain has fallen in the last 24hrs. The gauge is reset every 24hrs for accuracy and if rainfall exceeds expectations a graph is plotted to measure how much rain should fall on average for the following few days.
What is the principle of maximum-minimum thermometers?
The advantage is the thermometer records a daily maximum and minimum temperature for reference. The disadvantage is the thermometer must be reset each day.
How was the six's thermometer invented?
A combination maximum thermometer and minimum thermometer; the tube is shaped in the form of a U with a bulb at either end; one bulb is filled with creosote which expands or contracts with temperature variation, forcing before it a short column of mercury having iron indexes at either end; the indexes remain at the extreme positions reached by the mercury column, thus indicating the maximum and minimum temperatures; the indexes can be reset with the aid of a magnet.
How is a minimum thermometer reset?
BY MERSURING
What is the use of the magnet in a 6s thermometer?
To reset the index
What thermometer measures maximum and minimum pressure?
There is no special name for a maximum-minimum thermometer. It generally consists of two scales one will push a slider up as the temperature increases and the other thermometer pushes a slider down as the temperature goes down. You read it by observing the position of the sliders and then reset it so that the sliders return to the current temperature.
Why steel pointer is used in maximum and minimum thermometer?
These wee steel bars are known as riders, and they mark the travel extent of the Mercury column. They are held in place by a feeble magnet. When the reset button is pushed, it moves the magnet away from the tube, and the riders will settle.
How do you read a maximum minimum thermometer?
Each side is read at the bottom of the marker that has been pushed upward since the last reading. Don't read the colored fluid where it is at that time. That would only give you the current temperature. The bottom of the maximum marker is at the highest point that it was pushed to at the warmest time since the last reset, and the base of the minimum marker is where the liquid reached at the coldest time. The markers need to be reset at the same time each day with a magnet. Drag the markers back so they are both sitting on top of the silver mercury near the bottom of the tube. Horizontal thermometers are reset by turning them to vertical.

What is the actual use of six thermometer?
It consists of a U-shaped glass tube with two separate temperature scales set along each arm of the U. One of these is for recording themaximum temperature encountered and the other for the minimum temperature. The arms of the U-shaped tube terminate in sealed glass bulbs. The bulb at the top of the minimum reading scale arm is full of alcohol, the other contains a vacuum (or low pressure alcohol vapour). [1] [2] In the bend of the U is a section of mercury. This is pushed around the tube by the thermal expansion and contraction of the alcohol in the first bulb as it responds to the external temperature. The near vacuum in the other bulb allows free movement of the alcohol and mercury. It is the alcohol which measures the temperature; the mercury indicates the temperature reading on both scales. The thermometer shows a reading at the top of the mercury section on both the maximum and minimum scales; this shows the current temperature The maximum and minimum readings are recorded by two small steel markers which are sprung into the capillary tube so that they cannot easily slide unless a small force is applied to them. 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. Any change in temperature after that time will push one of the markers along with it. If the temperature is rising, then the maximum scale marker will be pushed. If it falls after the reset, then the moving mercury will push the minimum scale marker. Often both things happen one after another as the temperature changes, say through a twenty-four-hour period (see diurnal temperature variation). The markers thus record the furthest point reached by the mercury in each arm of the tube. They record the extremes of temperature experienced by the device since it was last reset. The thermometer is usually reset every day, but if left for longer the readings would show the highest and lowest temperatures encountered since the instrument was last reset. To take a reading, the positions of the ends of the markers nearest to the mercury are examined. Their positions on the maximum and minimum scales show the highest and lowest temperatures encountered over the period of measurement

How do you reset an outside thermometer on a 2006 Grand Caravan?
To reset an outside thermometer on a 2006 Grand Caravan simply take your caravan to the garage.
Why is lab thermometer can't be used as clinical and vice - varsa?
A clinical thermometer typically shows a maximum reading while a lab thermometer typically shows the temperature right now. When you take a thermometer out of a patients mouth (or other place that you are measuring the temperature) you most often want the maximum temperature to keep showing until you reset the instrument. When using a lab oratory thermometer you want the instrument to react as quickly as possible so that changes (up and down) can be noticed and recorded.
