Test Kit Zinc 0-5ppm

Test Kit Zinc 0-5ppm It is a colorimetric chemical test kit that determines the zinc concentration in samples within a 0.0 to 5.0 mg/L (ppm) range. It is a chemical test kit that uses an adaptation of the zincon method to measure zinc. It is supplied complete with all of the reagents and equipment necessary to perform 100 tests.

Zinc imparts an undesirable astringent taste to water. Tests indicate that 5% of a population could distinguish between zinc-free water and water containing zinc at a level of 4mg/litre (as zinc sulfate)*. In tapwater, the zinc concentration can be much higher as a result of the leaching of zinc from piping and fittings*. Drinking-water usually makes a negligible contribution to zinc intake unless high concentrations of zinc occur
