Tool used to measure the temperature?

Answer 1

Whilst a thermometer may give an 'estimated' readout of which can be right within a few percent of the actual value, this is not very accurate at all.

There are of course several different types of thermometers. Some made with quicksilver. Others made with alcohol. With the development of transistors, we started to develop electronic thermometers of which can work in many different ways. they can measure infrared radiation. they can measure intensity and spectrum of light. they can measure with probes of various metals.

The art of measuring temperature is a difficult one.

Most thermometers only work accurately within a short range.

You would for instance not use a thermometer filled with quicksilver or alcohol in order to measure the temperature in a pot of molten lead!

First you need to narrow down the field, then you can begin with the right (mostly costly) thermometer for the task.

A piece of copper wire can be used in order to measure temperature between -200 and + 150 degrees Celsius.

We know that the resistance in copper changes with a certain percentage per degree Celsius. With a bit of calculations we will be able to calculate the temperature to almost perfection if we only know the exact dimensions of the copper wire used.

Whilst our best mathematical efforts show possibilities, we still have to be sure that we measure the resistance to a very high degree of perfection too, but this is another subject.
