Description
Overview
GAOTek Portable Water Quality Test Equipment is a portable analyser for test heavy metal elements in different kinds of waters with good accurate and fast time. It also integrates high sensitivity Anodic and fast international standard Colorimetric methods. Anodic method has been classified as a standard detection method by the EPA, all authorities in America and all over the word, such as the EPA7063 and EPA7472 for different kinds of waters such as Mineral water, natural water, spring water, tap water. At the same time, Colorimetric methods are widely used for polluted water analysis. This analyser cover elements as Cu, Cd, Pb, Zn, Hg, As, Cr, Ni, Mn and Tl, with detection ranges from 0.1 ppb to 60 ppm.
