contact sensor
How can check refrigerator if its working fine?
Unless your refrigerator has a built-in thermometer, you would need to check it with a thermometer. Purchase of a refrigerator thermometer is highly recommended.
What is the difference between a digital and a basal digital thermometer for taking temperatures?
The digital thermometer is less acurrate then the basal digital thermometer. they use different methods of working. iter than that there is no difference.
How do you tell how hot or cold something is?
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
What are the types of thermometer?
Celsius, Fahrenheit, and Kelvin.
What is the working and construction of thermometer?
WORKING: Place the bulb of the thermometer filled with mercury in a vessel ov small pieces of ice the mercury will arise in the tube and will come to rest at a certain point.this point shows the melting point of ice. CONSTRUCTION:A thermometer consists of a glass bulb filled with mercury.A cappilary tube arises from this bulb.Due to the narrow bore of the tube a small change in the volume of the mercury becomes significiantly visible.
Why does a clinical thermometer has a kink in it?
So the working fluid doesn't flow back into the bulb when the it is removed from the heat source. This makes a clinical thermometer "sticky"; it retains the reading of the highest temperature experienced until it is "reset" by shaking.
Who invented the temometer?
you mean thermometer? If so, The first recorded thermometer was produced by the Italian, Santorio Santorio (1561-1636) who was one of a group of Venetian scientists working at the end of the Sixteenth Century. As with many inventions the thermometer came about through the work of many scientists and was improved upon by many others.
