For what purposes is an infrared thermometer used?
Infrared thermometers or laser thermometers as they are someimes known are useful for measuring temperature under circumstances wprobe type sensors cannot be used .
How should thermometer be maintained?
Many digital and infrared thermometers are self-calibrating.mercury thermometers should be shaken down prior to every use and left in place for at least three minutes. They require careful storage.and thorough cleaning after each use.
Why is mercury used in clinical thermometers?
These days, mercury is considered too risky to use in thermometers (due to the risk of them breaking and contaminating people). Alternate techniques are used today in clinical thermometer, including electronic thermometers and ones based on liquid crystals that aren't as harmful should they leak out and even contactless infrared thermometers..Mercury was used in clinical thermometers due to:Its high thermal expansion (25 °C) 60.4  µm·m−1·K−1Linearity in thermal expansionSensitivity to rise in temperature

How are mercury thermometers used today?
Mercury thermometers are rarely used, except in lab thermometers. For human use, they have been replaced by dyed alcohol glass thermometers, or electronic digital thermometers.
How do laser thermometers work?
Laser thermometers are actually just infrared thermometers. The laser is actually just there to make the thermometer easier to aim.

What are some of the uses for an infrared thermometer?
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.
How can you find more information about digital infrared thermometers?
Digital infrared thermometers are very reliable and often used in cooking to determine the temperature of both ovens and food. More information can be found about them through websites such as Amazon.
What is an infrared laser thermometer used to measure?
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".
How does aural thermometer measure temperature?
Digital ear thermometers measure the infrared radiation coming from an eardrum.
How does an aural temperature measure temperature?
Digital ear thermometers measure the infrared radiation coming from an eardrum.
How does an Aural thermometer measure temperature?
Digital ear thermometers measure the infrared radiation coming from an eardrum.
What instrument measures higher temperature?
Special thermometers for high temperatures, thermistors, thermoresistances, thermocouples, infrared detectors.
Different types of thermometers?
Celsius and Fahrenheit Thermometers Clinical Thermometers Ear (Tympanic) thermometers Pacifier Thermometers Underarm or Oral Thermometers Food Thermometers Outdoor Thermometers Mechanism of Different Types of Thermometers Mercury and Alcohol Thermometers Digital Thermometers Alcohol thermometer Beckmann differential thermometer Bi-metal mechanical thermometer Electrical resistance thermometer Galileo thermometer Infrared thermometer Liquid Crystal Thermometer Medical thermometer (e.g. oral thermometer, rectal thermometer, basal thermometer) Mercury-in-glass thermometer
How does an infrared thermometer work?
The amount of infrared energy in an area varies with temperature, so the infrared thermometer focuses that energy onto a detector and converts it into an electronic signal that reports the temperature.
How should thermometer be maintained?
Many digital and infrared thermometers are self-calibrating.mercury thermometers should be shaken down prior to every use and left in place for at least three minutes. They require careful storage.and thorough cleaning after each use.
