This test kit uses a "drop test" format, where a few drops of the reagent are added to the sample, and the color change is compared to a color chart to determine the chloride concentration
A conductivity reading of 1600 µS/cm in a lab is typically used as a measure of the amount of dissolved ions in a water sample, often indicating a relatively high level of impurities or salinity, and is commonly used in applications like water quality testing, environmental monitoring, and industrial processes to assess the purity or potential contamination of a water source; a higher µS/cm value signifies more dissolved ions present.
