Abstract For overcoming the limitation of the present water colority measurement method and meeting the requirement of measuring the water colority automatically, a measuring method of the water colority by color difference value is proposed. The relationship between color difference value and water colority value has been established by experiments, and the water colority value can be obtained based on the color difference value which calculated by measuring the spectral transmittance of water sample. Based on the proposed method, the calibrated system no longer needed the standard solutions during measurement and can be applied to measure any color of water sample. The measurements of natural water show that the measuring results are not only conforming to the measuring results by national standard method, but also higher sensitivity and better repetitiveness.
