What is thermometer and its uses?
A thermometer is a tool that measures temperature — how hot or cold something is. Thermometers are used to see if you have a fever or tell you how cold it is outside. Doctors use thermometers to check your body temperature — a very high or low body temperature means you’re sick.
What is the basic principle of a thermometer?
The basic principle is measuring temperature through merucury liquid as the mercury expands quickly by heating process and contracts in cooling process.
How does a body thermometer work?
An electronic thermometer works by putting a voltage across its metal probe and measuring how much current flows through it. A microchip inside the thermometer measures the resistance and converts it into a measurement of temperature.
Which type of thermometer is best for adults?
Tympanic thermometers When positioned properly, infrared ear thermometers are quick and generally comfortable for children and adults. Infrared ear thermometers are appropriate for infants older than age 6 months, older children and adults.
Which type of thermometer is the most accurate?
Rectal thermometers, which go into your rear end, are the most accurate, but they can be uncomfortable. Armpit, ear, and forehead thermometers aren’t as accurate. Most doctors think an oral thermometer, which you hold under your tongue, is best. Don’t use an old glass thermometer.
What is normal forehead temperature?
001) The most accurate one was chosen, and the normal range of forehead temperature in 1000 subjects detected by this method was 31.0 degrees C to 35.6 degrees C. Conclusions: Our study shows that commercially available, handheld infrared thermometers require individual validation.

What is an infrared thermometer best used for?
An Infrared Thermometer is a handheld device that can display temperature readout on it after scanning portions of an object or area with the built-in laser. The main use of the infrared thermometer is to read a particular spot on a surface of the wall, ventilation, automobile, or food item.
How accurate is infrared thermometer for humans?
Research has shown that, when used correctly, infrared or no-contact thermometers are just as accurate as oral or rectal thermometers. No-contact thermometers are popular among pediatricians, as kids often squirm around when trying to get a temperature read, but it also holds true in mass temperature screenings.
How safe is infrared thermometer?
Clinical infrared thermometers are completely safe to use on everyone – babies, children, and adults as long as you don’t point the laser beam into their eyes. These non-contact devices also allow measuring the temperature of humans from a safe distance.
What are the advantages of infrared?
10 advantages of infrared heating panels
