It is a simple device. A variable electronic resister, called a thermistor, is used and is on the end of the cord. The resister varies it's resistance value depending on temperature. The probe must be placed in the area (outside) where you want the temperature. There is a second one in the unit itself and will show the inside temperature.

Will a thermometer work up side down?
In general, a traditional mercury or digital thermometer needs to be held upright for accurate readings. Placing it upside down could affect the positioning of the mercury or the sensor, leading to inaccurate temperature measurements.
How does mercury work in a thermometer to measure temperature accurately?
Mercury in a thermometer expands and contracts with changes in temperature. As the temperature rises, the mercury expands and rises in the tube, and as the temperature falls, the mercury contracts and lowers in the tube. This movement is then converted into a temperature reading on the scale of the thermometer, allowing for accurate temperature measurement.
How does a mercury thermometer work to measure temperature?
A mercury thermometer works by using the expansion and contraction of mercury in response to temperature changes. As the temperature rises, the mercury expands and rises up the narrow tube, indicating a higher temperature. Conversely, as the temperature decreases, the mercury contracts and lowers in the tube, showing a lower temperature. The temperature is read by looking at the level of the mercury in the tube against a scale marked on the thermometer.
How do themometers work?
Thermometers work by measuring temperature using a temperature-sensitive component, like a liquid, gas, or a digital sensor. When the temperature changes, the component inside the thermometer expands or contracts, and this change is indicated on a scale as a temperature reading.
Why clinical thermometer is jerked before using it again?
If you have an old thermometer that has mercury, then the shaking makes all of the mercury flow to the bottom of the thermometer. Then, you can get a better reading. The current digital ones work differently. Thermometers used for taking people temperatures are a special kind that go up with heat but don't go down with cold. So you have to shake a thermometer before taking your temperature to make the reading go down below your own temperature. Then the thermometer can go up again to read your temperature.

How does Mercury work?
Temperature affects the amount the mercury is spread out. Heat causes most liquids to expand, which is how a thermometer works. As heat around the glass protecting the mercury of the thermometer rises, the mercury expands and covers more room in the thermometer.
Why would a mercury thermometer not work below -39 degrees Celsius?
Mercury freezes at around -39 degrees Celsius, so below this temperature, the mercury in the thermometer would solidify and no longer be able to expand and contract with changes in temperature, rendering the thermometer unusable.
How long should you keep the thermometer under your tongue?
You must hold your mouth closed and keep the thermometer in place for a certain period of time. If you have a digital thermometer, it will tell you when it's "done". If you are using an old "mercury thermometer", the thermometer must stay under the tongue for at least a minute to 2 minutes.NOTE: Mercury thermometers are being phased out. The mercury inside is highly toxic and you should dispose of all mercury thermometers by taking them to a recycling center that handles that. DO NOT THROW IT IN THE TRASH. Mercury is poisonous to every living thing.UPDATE: GERATHERM offers MERCURY FREE thermometers that work the same as the mercury ones. They are supposed to be safe.

How does the kink in a mercury or alcohol work in a clinical thermometer?
The kink in a mercury or alcohol clinical thermometer helps to prevent the mercury or alcohol from flowing back into the bulb once the thermometer is removed from a patient's body. This ensures that the maximum temperature reached during measurement is retained for reading.
How a laboratory thermometer work?
It works when the thermometer gains heat from the surroundings. When the thermometer gains heat from the surroundings, gradually Mercury expands and it points the accurate measurement of temperature.
What does a thermometer measure and how does it do it?
A thermometer is a device that measures temperature or temperature gradient using a variety of different principles. The word temperature comes from the Greek work thermo which is heat and meter to measure.
What thermometer would be used to collect data over a twenty four hour period of time?
You can use the recording thermometer or the mercury thermometer, either one of those will work.
Which is the suitable thermometer for measuring the boiling point of water?
The most suitable thermometer for measuring the boiling point of water is a mercury thermometer or a digital thermometer with a high temperature range. These thermometers are able to accurately measure the high temperature of boiling water without being damaged. It is important to ensure that the thermometer is calibrated and accurate for precise measurements.
How does a mercury thermometer work to measure temperature?

Conversely, as the temperature decreases, the mercury contracts and lowers in the tube, showing a lower temperature. The temperature is read by looking at the level of the mercury in the tube against a scale marked on the thermometer.
How does an digital thermometre work?
A digital thermometer has a digital controller called a microcontroller inside of it that measure the thermistors teperature by measuring its electric resistance. Then it displays it on a little LCD screen.
