Dirui's biochemical analyzer is quite good. It seems that their DiRui biochemical assembly line and Mindray blood cell assembly line have entered the national "863" plan. Also, the Siemens 1300 biochemical analyzer is OEMed by Dirui Biochemical, so it is still OK. But they all said that it was indeed a Hitachi imitation, so the instrument was good. Anyway, Di Rui and Mindray are still good in China. Others such as Kehua Zhong, Innova, Senlong, Baxter, etc. are relatively poor.
