ABSTRACT:
A chemical reaction test piece having arranged at prescribed intervals on its elongate substrate a plurality of carriers having impregnated therein reagents and test fluids is mounted on a table, and the reflection light of a light irradiated onto the carrier from a lamp is converted into a measurement electrical signal by a photoelectric converter. A reference reflection carrier is further provided on said substrate or table, and a light reflected from said reference reflection carrier is converted into a reference electrical signal by the photoelectric converter, and said measurement electrical signal is calibrated relative to a change with time in a signal detection system including said lamp and photoelectric converter using said reference electrical signal. The calibrated measurement electrical signal is subjected to data processing to be converted into a test data, and this test data is compared with a reaction comparison data previously stored in a memory, and the comparison result is printed on a recording paper by a printer.
