ABSTRACT:
A sugar concentration gauge of a type for measuring the sugar concentration of test liquid applied to a light incidence surface of a prism through detection of a refraction angle, with which a light beam having passed through the test liquid is emitted from the prism and which corresponds to the sugar concentration of the test liquid. The gage has a movable plate capable of adjustment with respect to the light incidence surface of the prism, a light incidence plate on the movable plate so as to be superposed on the light incidence surface of the prism, and a weight on the movable plate for exerting a vertical load onto the light incidence surface of the prism, whereby the test liquid can be uniformly spread on the light incidence surface of the prism without being influenced by the kind and amount of the test liquid.
