ขี้เกียจแปลจัง Correlate the values of NTU to mg/l defined by the standard. Define a conversion factor between NTU reading and mg/l. For example, the turbidity meter may read 15 NTU and the concentration of the standard solution to yield this response may be 5 mg/l. The conversion factor would be 1 mg/l = 3 NTU = 1 ppm based in the definition that 1 mg/l = 1 ppm. Each application may have a different conversion factor due to the varying response of the turbidity instrument based on the particulars of the application and samples.
