Why is There a Deviation in the Transmittance Indication of the Colorimeter?

As a common instrument for quantitative analysis of chemical substances, photometers are widely used in scientific research, production, medical treatment, laboratory, and other fields. In order to ensure the accuracy and reliability of the measured values of the instrument, the colorimeter must be verified according to JJG178- 2007 “Verification Regulations for Ultraviolet, Visible and Near-Infrared colorimeters”. …

What are the Reasons for the Poor Measurement Accuracy of Colorimeter?

When a colorimeter is used to measure the measured object, the direct result obtained by the instrument is the refraction ratio of the measured material to the incident light of the selected wavelength. The transmittance is determined by the spectral properties of each measured substance. Therefore, it is directly related to the selection of the …
