[The Development of SH-C1 Autobiochemical Analyzer].

As a miniature automatic analyzer, SH-C1 analyzer can be divided into five parts: the diluter, the circular reaction plate, the photometer, the electronic control board and the main microcomputer system with CRT monitor. The paper discusses its general structure and its key parts: the double-beam high precision photometer and the diluter controlled by microprocessors. The paper also describes the software system and the properties of the instrument.
