The HI727 Checker®HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure the color of water. Used in drinking water and wastewater, the color of water may indicate the presence of undesirable and potentially harmful material, such as organic matter. Other harmless constituents of water such as tannins, iron and manganese, may also be present and impart color. The HI727 reports color of water from 0-500 PCU (Platinum Cobalt Units).
