An instrument designed for measuring the mechanical effect of radiant energy.
An instrument to measure the changing levels of radiation as well as visible and infrared light. They can produce cloud images even at night.
a device that detects and measures electromagnetic radiation.
See Infrared radiometer.
An instrument that measures radiance, or the radiation emitted by an object.
an instrument that detects and measures electromagnetic radiation in discrete spectral bands of the electromagnetic spectrum
An instrument for quantitatively measuring the intensity of electromagnetic radiation in some band of wavelengths in any part of the electromagnetic spectrum. Usually used with a modifier, such as an infrared radiometer or a microwave radiometer.
An instrument designed to measure spectral irradiance. Spectroradiometers gathered the data in NREL's Solar Spectral Radiation Data Base.
Device that detects and measures electromagnetic radiation. [NOAA
meter to detect and measure radiant energy (electromagnetic or acoustic)
a detection system that measures incident radiation
a device used for detecting and measuring radiation
an instrument for detecting and measuring the intensity of the sun's energy in the electromagnetic spectrum
an instrument that measures radiant energy
a passive instrument, thus it uses radiation from an external source
a tool, a very effective tool, at measuring the parameters of UV irradiance and UV dosage
Any instrument or device that senses and measures the radiant energy in electromagnetic radiation.
A passive device for intercepting and quantitatively measuring electromagnetic radiation in a band of wavelengths.
An instrument for detecting and measuring electromagnetic radiation. Satellite radiometers detect the radiation (both visible and infra red) reflected from the Earth below. As Meteosat spins (at 100 rpm), its radiometer telescope scans the surface of the earth and clouds, building up an electronic picture of the surface. See also AVHRR.
a device that measures the total energy or power from an object in the form of radiation, especially infrared radiation
An instrument which measures radiation levels. Such an instrument can be calibrated in power or temperature.
An instrument for measuring radiant energy. See actinometer, Dines radiometer, photometer, Tulipian radiometer.
An instrument for detecting and measuring radiant energy.
An instrument, distinct from a photometer, to measure power (watts) of electromagnetic radiation.
A Radiometer is a meter that measures irradiance of invisible light levels, expressed in Watts per square centimeter (W/cm2).
an instrument that detects and measures the intensity (concentration) of light energy
An instrument designed to measure the intensity of radiant energy.
An apparatus thought to measure radiant energy of heat and light, consisting of a set of vanes, shiny on one side and blackened on the other, mounted in an evacuated vessel.
An instrument that measures radiated electromagnetic power. Radiometers operating at infrared and microwave frequencies are used in passive atmospheric remote sensing.
A radiometer is a device used to measure the radiant flux or power in electromagnetic radiation. Although the term is perhaps most generally applied to a device which measures infrared radiation, it can also be applied to detectors operating any wavelength in the electromagnetic spectrum.
