It is a thermometer using the platinum wire as sensor (resistance thermometer); the resistance of the wire is proportional to the temperature. This type of thermometer is used under 600 0C.

Thermometer use to measure temperature above 1250 celsius?
platinum resistance thermometer
How does a platinum resistance thermometer work?
They are slowly replacing the use of thermocouples in many industrial applications below 600 °C, due to higher accuracy and repeatability.Common RTD sensing elements constructed of platinum copper or nickel have a unique, and repeatable and predictable resistance versus temperature relationship (R vs T) and operating temperature range. The R vs T relationship is defined as the amount of resistance change of the sensor per degree of temperature change.
Where does the thermometer be used at?
Depends on the thermometer. If it's a weather thermometer, then you use it outside. If it's a body temperature thermometer, then you use it in the mouth or behind.
The use of thermometer?
the thermometer is used to measure the temperatures.
What measures how cold or hot something is?
a Thermometer.
Thermometer use to measure temperature above 1250 celsius?
platinum resistance thermometer
Why platinum is used in platinum resistance thermometer experiment?
Platinum resistance thermometer requires a small current to pass through it to determine its resistance at different temperatures. Platinum has a linear resistance-temperature relationship; we can use this method to find the resistance at different temperatures.
What is the function of compensating leads in the platinum resistance thermometer?
It is used for the compensation of the platinum wire. in direct sense of current.
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.
