DHF82 Multi-element fast analyzer

DHF82 multi elements high-speed analytical instrument is developed on the basis of photometric analysis principle. It adopts unique measures to extend the linearity and to increase the sensitivity. It settles the problems of linear deviation and poor sensitivity for the conventional photometric analysis method.

High-precision and high-speed analysis is successfully achieved in a wide range. System analysis of eight elements and eighteen elements were finished in 1994 and 2000 respectively. Furthermore, system analysis of twenty elements was finished in 2002. This analytical instrument is the most advanced both at home and abroad. This instrument has remarkable advantage in the field of silicate system analysis. It is specially suitable for the industries of ceramics, refractory, cement, glass, geology and nonmetal deposits. This analytical instrument has been successfully used by over 100 universities, research institutes and factories. It is well received by the users. Above all, it has been widely sold in overseas market.
