The standard "SL 87-1994 Determination of transparency (transparency meter method, disc method) " specifies the transparency method for the determination of water using the transparency meter method and the disc method. This standard describes in detail the scope and method of application of the transparency meter method and the disc method for the determination of transparency in natural water and lightly polluted water, as well as in ground water. Transparency meter method: The use of specific transparency meter equipment to evaluate the transparency of water by measuring the height of the water column. The specific method includes thoroughly mixing the water sample, gradually reducing the height of the sample until the printing mark can be clearly seen, and finally taking the average value as the result. Disc method: In-situ measurement using a Serpentine disc, suitable for surface water, and transparency is judged by observing the visibility of the disc in the water. This standard not only ensures the accuracy and reliability of the measurement, but also provides detailed instructions on precautions and result judgments to help users correctly perform transparency determination. It is suitable for application needs in many fields such as environment protection and water quality monitoring.
