ColoriMeter spectroPhotoMeter

Colorimeters and spectrophotometers perform quantitative analysis based on the absorption characteristics of substances to light of specific wavelengths. Light emitted from the source is converted into monochromatic light by the optical system, passes through the sample, and is then measured by a detector to determine changes in light intensity. They are used for measuring solution concentrations and analyzing components, with common applications in environmental monitoring, food testing, and industrial quality control.
Selection
When selecting, consider that the measurement wavelength range should cover the characteristic bands of the analyte, and the spectral bandwidth should match the detection accuracy requirements. Pay attention to photometric accuracy and stray light indicators, ensuring the sample chamber size is compatible with standard cuvettes. Verify the automatic wavelength calibration function and data output interfaces, and ensure the operation interface is simple and intuitive. Regularly use reference materials to verify the stability of the instrument.
