About Radiometers

Radiometers are used to measure the intensity of electromagnetic radiation (e.g., UVC, UVB, UVA, Vis, and IR). They are univariate devices that do no distinguish between light of different wavelengths. In addition to wavelength range, radiometers carry specifications such as sensor diameter, power range, accuracy, resolution, operating temperature range, and humidity range.  The wavelength range specifies the detection range for radiometers. The sensor diameter measures the active part of the sensor. Power range is the power per unit area. Radiometer accuracy is usually given as a percentage. The resolution of the detector is a measure of radiometer sensitivity. Operating temperature and humidity range are also important specifications to consider when selecting radiometers.

Radiometers differ in terms of display type. Choices include needle indicator, numeric, alphanumeric, and video. A needle indicator is a face upon which an analog measurement is registered, typically by means of graduations and a pointer. Radiometers with a numeric indicator display the output in whole numbers, usually in digital form. Devices with an alphanumeric indicator display the output as both letters and numbers, generally in digital form. Radiometers with video displays may use a cathode ray tube (CRT), liquid crystal display (LCD), or other multi-line form.
