WebThe photometric accuracy and linearity of a spectrophotometer determine its ability to measure the absorbance of compounds, which is directly related to known absorptivity or concentration. Photometric accuracy determines how accurately the instrument measures the absorbance of a sample. Poor photometric accuracy will produce incorrect results. A photometer is an instrument that measures the strength of electromagnetic radiation in the range from ultraviolet to infrared and including the visible spectrum. Most photometers convert light into an electric current using a photoresistor, photodiode, or photomultiplier. Photometers measure: northland taxi shuttles

Photometer - Wikipedia

WebA photometer measures relative rather than absolute intensity. The Bunsen photometer (named for R. W. Bunsen) determines the light intensity of a source by comparison with a known, or standard, intensity. The two light sources (one of known, one of unknown intensity) are placed on opposite sides of the surface (a disk of paper) to be illuminated.
