Infrared thermometer is famous for its easy usage and accuracy in measuring temperature of items. Objective To evaluate the performance of a non-contact infrared thermometer (NCIT) in comparison with digital axillary thermometer (DAT) and infrared tympanic thermometers (ITT) in a population of healthy at term and preterm newborns nursed in incubators.
For public health authorities, it provides a simple, quick, Non-contact, and non-invasive way to perform preliminary mass-screening non contact infrared thermometer for H1N1 fever (swine flu) infection symptoms (body temperatures above 98.6 degrees Fahrenheit or 37 degrees Celsius).

It's good value for money for the amount of things this thermometer does, it's extremely quick at reading and is very accurate as I tested it against my other 2 thermometers and you can even set the date and time on it. It's also great for if you need to use it in the middle of the light and don't want to switch all the lights on as the screen lights up in blue.
Thus, these results were presented as mean, SDs and 95% CI. To compare body temperatures obtained in each newborn using the three methods, the mean value of the bilateral axillary measurements with the digital axillary thermometer, the mean value of the bilateral tympanic measurements with the ITT and the mean value of the two mid-forehead measurements with the NCIT, were calculated.

In today's market, more thermometers are used without firstly being checked for traceable accuracy, or suitability of purpose, yet the accuracy and suitability of your thermometer to its intended application could be the difference between passing and failing a health & safety audit, wasting a whole industrial process, or being correct the first time.
Braun stands by ear temperature readings as the most accurate way to detect fever, even when other brands sing the praises of forehead readings, explaining that the blood supply in the eardrum shares the temperature control center of the brain, so it's the best place to detect unusual temperature changes.
Some typical circumstances are where the object to be measured is moving; where the object is surrounded by an electromagnetic field , as in induction heating ; where the object is contained in a vacuum or other controlled atmosphere; or in applications where a fast response is required, an accurate surface temperature is desired or the object temperature is above the recommended use point for contact sensors, or contact with a sensor would mar the object or the sensor, or introduce a significant temperature gradient on the object's surface.
