1. Actinometer

   Actinometers are instruments used to measure the heating power of radiation. They are used in meteorology to measure solar radiation as pyranometers, pyrheliometers and net radiometers. An actinometer is a chemical system or physical device which determines the number of photons in a beam integrally or per unit time. This name is commonly applied to devices used in the ultraviolet and visible wavelength ranges. For example, solutions of iron(III) oxalate can be used as a chemical actinometer, while bolometers, thermopiles, and photodiodes are physical devices giving a reading that can be correlated to the number of photons detected.

1. actinometer

   An actinometer is a device used to measure the intensity or strength of electromagnetic radiation, particularly that of solar radiation. This usually involves a chemical reaction or changes in electrical properties to gauge the radiated energy. Actinometers are often used in meteorology and by environmental or climate researchers.
