Abstract
A photometering apparatus for use in a chemical analyzer of multi-channel type includes a liquid type thermostat made of transparent material and a block made of transparent material and movably mounted on a bottom wall of the thermostat, a number of reaction vessels being constituted by depressions formed in said block in a matrix form. An absorption of a test liquid contained in respective reaction vessels on each channel is measured by projecting a light beam emitted from a light source incident perpendicularly upon the test liquid and by receiving the light beam transmitted through the test liquid, a bottom portion of the reaction vessel and the bottom wall of thermostat.
