This standard specifies the classification, requirements, test methods, inspection rules, signs, Encasement, transportation and storage of fluorophotometers. Fluorimeter is suitable for quantitative analysis of discontinuous sampling when the filter obtains monochromatic light. The type of Fluorimeter is single beam of light, fixed wavelength, filter excitation, emission type, Wavelength range is 330nm~ 650nm. The normal working conditions of Fluorimeter include Environmental temperature between 5 ° C~ 35 ° C, relative humidity not more than 85%, power supply 220V +/- 22V, Frequency is 50Hz +/- 1Hz, and it is not affected by vibration and electromagnetic field interference.
