Definition von actinometer im Englisch Englisch wörterbuch
A device used to measure the heating power of electromagnetic radiation, especially that of solar radiation
(sol) (meas) An instrument used to measure DIRECT RADIATION from the sun F - actinometre S - actinometro
This is the instrument used to measure direct radiation from the sun Also known as pyrheliometer
an instrument for measuring the intensity of electromagnetic radiation (usually by the photochemical effect)
An instrument which measures the intensity of radiation by determining the amount of chemical change or fluorescence produced by that radiation
The general name for any instrument used to measure the intensity of radiant energy, particularly that of the sun Actinometers may be classified, accordingly to the quantities that they measure, in the following manner: 1) pyrheliometer, which measures the intensity of direct solar radiation; 2) pyranometer, which measures global radiation (the combined intensity of direct solar radiation and diffuse sky radiation); and 3) pyrgeometer, which measures the effective terrestrial radiation See actinometry, bolometer, dosimeter, photometer, radiometer; compare sunshine recorder
