Abstract

PURPOSE:To prevent the dispersion in prepared silver halide, by specifying the flowing-out speed of a comparison electrode of a double junction construction. CONSTITUTION:A comparison electrode measuring PH and P Ag of solution consists of an outer cylinder 1, an outer cylinder liquid 2, a junction 3 of the outer cylinder 1, an internal electrode 4, a junction 5 for the internal electrode, an internal liquid 6, a filling inlet for the liquid 6, and a lead 8. As a raw material of the junction 3, porous members such as ceramic and glass flit are used. The flowing-out speed of the outer cylinder liquid 2 from the junction 3 linking the liquid 2 and a liquid to be tested is set so that it exceeds 0.02ml/min at 10cm of the height of the outer cylinder liquid at normal temperature and humidity. The height is controlled with the material of the junction 3 and the physical shape. The performance for photography is made stable by giving the uniformity for the measurement of a gelatin water solution.
