Photometric instrument
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: WebJul 10, 2024 · Note: Scratches, pipette errors and other errors in the handling of the measuring instruments additionally influence the accuracy of the measurement results and lead to a higher inaccuracy!
