Even though Zinc is nontoxic to humans, concentrations above 5mg/L can cause a bitter astringent taste. At these levels of concentration is can result in a milky iridescent colour in alkaline water and irritate the human digestive system.
Zinc in low quantities, however, is a beneficial and essential element necessary for body growth. In addition to drinking water, Zinc is measured in surface finishing, boilers and cooling towers, water conditioning and effluent waters to name but a few.
The Hanna HI-93731 Zinc Meter is extremely easy to use and gives direct readout on the digital display in mg/L(ppm). To obtain a reading simply take a small sample of water in the glass cuvette supplied, add the reagent (not included), and then place the cuvette in the measuring chamber of the instrument.
