HANNA HI93714 Cyanide Photometer

Cyanide is a pollutant that originates mostly from metallurgical and galvanic industrial plants. Cyanide is extremely poisonous to the human nervous system, and it is therefore imperative to monitor and control its level in potable water. Continuous monitoring in waste effluents is required, and cyanide is removed using alkaline chlorination procedures. Due to this, European norms limit the concentration of cyanide in drinking water to 0.05 mg/ L, while the EPA has established that the maximum level is not to exceed 0.2 mg/ L. HANNA® ' HI 93714 is the first electronic instrument of its kind to determine cyanide concentrations in water. The ideal replacement to test kits, HI 93714 will provide you with fast and accurate measurements at the touch of a button.
