Multi-wavelength spectroPhotoMeter

A multi-wavelength spectrophotometer emits beams of multiple wavelengths from a light source. After the sample absorbs specific wavelengths, it detects the intensity of the transmitted light to analyze the concentration or properties of the substance. It is used for quantitative measurements such as pigment detection in coatings and inks, plastic composition analysis, and water quality monitoring.
Selection
When selecting, consider that the wavelength range should cover the application requirements, such as from ultraviolet to visible light. Pay attention to the instrument's accuracy and stability to ensure consistency in repeated measurements. Evaluate sample compatibility and ease of operation to align with routine laboratory testing procedures.
