Which is more accurate, a thermometer or an infrared thermometer?
A medical-grade thermometer will always be more accurate than a kitchen infrared thermometer. Pointing either thermometer at the same point on your body will get you the same temperature reading (for practical purposes).
How does an IR thermometer measure temperature?
An IR thermometer derives temperature by measuring the intensity of IR radiation it sees.
How to check thermal imager accuracy?
The most certain way to check the accuracy of a thermal imager is to use a blackbody radiation source that provides a known and repeatable temperature source and is at a very high emissivity. These calibrations are conducted in a lab environment.

So when you point an IR thermometer at the sky, it is measuring the IR within it’s field of view which is typically around 15 degs of arc. If that small patch of sky has clouds, heated by the sun or IR coming from the ground, the temperature reading it displays is close to earth surface temperatures.
Why is an infrared thermometer important?
With this tool, you can get an accurate temperature reading on liquids without any cross-contamination, because the thermometer itself never makes contact. It simply reads the thermal, infrared energy coming from the surface of the liquid itself. 3.

This technique requires monitoring and recording your baseline temp over several days, or alternately using an NIST-traceable thermometer to know your IR gun’s correction factor.
Why is IR called black body radiation?
There is a reason why IR emission from hot objects is called “black body radiation”. The lighter the object is, ie, the closer to white or reflective it is, the less IR it emits for a given temperature. Medical IR thermometers are calibrated for the approximate color of skin.
Benefits of NCITS
- Non-contact approach may reduce the risk of spreading disease between people being evaluated
- Easy to use
- Easy to clean and disinfect
- Measures temperature and displays a reading rapidly
Limitations of NCITS
- How and where the NCIT is used may affect the measurement (for example, head covers, environment, positioning on forehead).
