An infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called blackbody radiation emitted by the object being measured. They are sometimes called laser thermometers if a laser is used to help aim the thermometer, or non-contact thermometers to describe the device's ability to measure temperature from a distance. By knowing the amount of infrared energy emitted by the object and its emissivity, the object's temperature can often be determined. Infrared thermometers are a subset of devices known as "thermal radiation thermometers".
The Fluke 62 Infrared Thermometer can be used to gauge the temperature of things from motors to liquids. They're most commonly found being used when repairing air conditioning.

Infrared thermometers or laser thermometers as they are someimes known are useful for measuring temperature under circumstances wprobe type sensors cannot be used .
Infrared thermometers are primarily used in the kitchen, for measuring the temperatures of hot liquids and solids. A good writeup on infrared thermometers and its method of working is on http://www.allqa.com/IR.html.There are some industrial applications as well.
These are materials used in thermometer whoses property varies with temperature
what are the sulfide mineral used to a thermometer
A thermometer used to measure air temperature uses a glass tube filled with a liquid either alcohol or mercury. When the temperature increases the particles of liquid expand, filling the glass tub. Thermometers that are used to measure you body temperature uses infrared sensors.
A non contact thermometer should be used when a quick temperature measurement is required. Non contact thermometers depend on infrared technology to measure the surface temperature of an object.
A Galileo thermometer is a thermometer made of a sealed glass cylinder containing a clear liquid and a series of objects whose densities are such that they rise or fall as the temperature changes.
Thermometric substance is the material used in the thermometer, whose property varies with temperature.
Dental materials are examples of materials that are used to make impressions.
