Infrared thermometers are a good first step for temperature screening but thermal cameras are the best choice for a long term and safe solution.
Thermal imaging camera vs infrared thermometer.
The low cost option would be an infrared thermometer.
Both spot pyrometers and thermal cameras work according to the same principle.
How to choose between infrared thermometers and thermal imaging cameras.
Thermal cameras are significantly more accurate allow safe social distancing and enable you to screen more people faster.
Infrared cameras receive gather and measure a beam of infrared light waves.
They detect infrared radiation and translate it into a temperature reading.
Thermal imaging cameras have multiple detectors measuring infrared in a pixel array and so provide a thermal image of the surface being measured.
In addition because of their advanced optics thermal imaging cameras can detect temperatures accurately over much greater distances than infrared thermometers can.
Infrared imaging can refer to any imaging system that operates in the infrared which extends from about 7 to 300 microns wavelength as lubos stated.
A spot that varies in size depending on the specification of the thermometer and its.
Another common tool for non contact temperature measurements widely used in industrial applications is the spot pyrometer.
Thermal imaging as the term is commonly used refers to an infrared imaging system designed specifically for the portion of the infrared range which is emitted by object at or just above room.
Infrared imaging shows the radiation energy that the objects emit within the infrared spectrum.
The way it works is that it measures the average surface temperature of a spot.
This feature makes the thermal image cameras most suitable for measuring the temperature in surveillance systems.
The result image is a combination of many variables but always includes the chosen lens the pixel matrix and the sensitivity of the detector.
Thermal imaging cameras are used for non contact temperature measurements in companies all over the world.
Thermal imaging systems offer certain benefits in that other methods need a closer proximity or contact to measure temperature for example non contact infrared thermometers or oral thermometers.
