Copper (soluble) CHEMets® Visual Test Kit - 0-1 & 1-10 ppm Copper CHEMets® Visual Test Kit is designed for easy and reliable detection of copper in a neutral solution. With the use of sodium bisulfite, cupric copper is reduced to cuprous ions, which then react with bathocuproine to form an orange-colored chelate. This allows for precise measurement of copper concentration, expressed in ppm (mg/L) Cu. A must-have for accurate analysis.
