Infrared Radiometer Overview
The infrared radiometer is a hand-held optical infrared radiometer with high precision, low power consumption, small size, stable performance, convenient use and portability. The infrared irradiance meter adopts Si PIN sensor, which can be used to measure the infrared irradiance of 850nm and 940nm LED luminescence. The measured data can be read directly through the digital meter, or connected to a computer for continuous recording and calculation and analysis.

Working principle of infrared radiometer
In nature, when the temperature of an object is higher than zero, due to the existence of its internal thermal motion, it will continuously radiate electromagnetic waves to the surroundings, including infrared rays with a wave band of 0.75µm to 100µm. The size of the infrared radiation energy of an object and its distribution by wavelength are closely related to its surface temperature. Therefore, by measuring the infrared energy radiated by the object itself, its surface temperature can be accurately determined. The infrared radiometer works according to this principle.
