Exempel på hur man kan använda PHOTOMETER i en mening

• Computers began to be used to observe and study massive amounts of astronomical data on stars, and new technologies such as the photoelectric photometer allowed astronomers to accurately measure the color and luminosity of stars, which allowed them to predict their temperature and mass.
• A nephelometer or aerosol photometer is an instrument for measuring the concentration of suspended particulates in a liquid or gas colloid.
• Luminous intensity of artificial light sources is typically measured using and a goniophotometer outfitted with a photometer or a spectroradiometer.
• Then, a photometer measures the absorbance of the sample to indirectly measure the concentration of analyte present in the sample.
• Sloane's best known invention, introduced in 1878, was the self-recording photometer for gas power — the first instrument to mechanically register the illuminating power of natural gas.
• Luminous flux of artificial light sources is typically measured using an integrating sphere, or a goniophotometer outfitted with a photometer or a spectroradiometer.
• A photometer or spectrophotometer is used to measure the attenuation of deep blue (violet) light at 430 nm, as it passes through 1 cm of beer contained in a standard 1 cm by 1 cm cuvette.
• His silver tester, photometer for pigment printing and heliotype printing, and universal spectroscope were introduced into general use.
• Most continuous flow analyzers depend on color reactions using a flow through photometer, however, also methods have been developed that use ISE, flame photometry, ICAP, fluorometry, and so forth.
• It also has two CCD cameras, a two-star "Nather-type" photometer, a "Faint-object spectrograph-camera" (FOSC), and an older Boller and Chivens spectrograph.
• These include cameras for fast photography, photoelectric photometers, a single-channel photoelectric spectrum scanner, a medium resolution spectrograph, a quartz-prism calibration spectrograph, infrared photometer, image tube spectrograph, a Universal Astronomical Grating Spectrograph (UAGS from Zeiss), high-resolution echelle spectrograph and a polarimeter.
• Two years later Stebbins used the photometer and discovered four stars to be eclipsing binary stars: Beta Aurigae, Spica, Alpha Coronae Borealis and Delta Orionis.
• Early products included a boiler feedwater flame photometer, a balloon hydrometer, a nerve gas detector, a lab refractometer and process control refractometers.
• If the sample volumes are large enough to use microplates or cuvettes, the dye-loaded samples can also be quantified with a fluorescence photometer.
• Terma was a high temporal and spatial resolution impulse photometer for observations of the rapidly changing optical signatures of polar aurorae, polar stratospheric clouds and lightning.
• According to the surveys carried out by the Infrared Astronomical Satellite IRAS (SIMPS and MSX), the Spitzer Space Telescope (MIPS photometer and MIPSGAL survey) and the NEOWISE mission of the Wide-field Infrared Survey Explorer, Neith measures between 11.
• Walraven constructed special photometers for the telescopes at the station, including the 5-color photometer for which he developed the Walraven photometric system.
• The method involves the use of a spectrophotometer or photometer to measure the attenuation of light of a particular wavelength, 430 nanometres (blue), as it passes through a sample contained in a cuvette of standardised dimensions located in the light path of the instrument.
