Ratio Monitoring PhotoMeter

Proportion monitoring photometers measure the absorption of light at specific wavelengths by comparing the intensity differences between the sample and reference beams. They are used to detect solution concentrations and monitor reaction progress, as well as to track component changes and reaction endpoints in fields such as chemical engineering and environmental protection.
Selection
Select the appropriate wavelength range based on the spectral characteristics of the substance to be tested; consider detection accuracy and match the measurement range with sample concentration; environmental adaptability must meet on-site dustproof and moisture-proof requirements; the operation interface should be simple and easy to read for daily maintenance.
