Grating PhotoMeter

The grating photometer uses a grating spectroscopic system to decompose composite light into monochromatic light, measuring the absorption of light by substances at different wavelengths. It is used to detect color parameters of paints and inks, light transmittance of plastic products, paper whiteness, and other indicators. In the laboratory, it is used in conjunction with standard samples for quantitative analysis.
Selection
Select transmission or reflection measurement mode based on the morphology of the sample to be tested. The wavelength range must cover the required band for the application, and the resolution should meet the detection accuracy requirements. Consider whether the sample chamber size is compatible with conventional specimens. The instrument's stability should be suitable for continuous testing environments, and the user interface should align with the operators' usage habits.
