Colorimeter and Concentration Meter Circuit
As the circuit shows, when the sample is inserted, the photosensitive resistor will transform its received light intensity into electrical signals according to the concentration or density of sample size, and drive display instrument through the amplifier. The measuring instrument is generally used for the concentration of emulsion, gray film density and transmittance measurements. Amplifier and display instruments can be selected according to specific needs. RP regulation can be detected by different samples.
