This dissolved oxygen analyzer (hereinafter referred to as the instrument) is mainly designed to facilitate the user to carry on-site operation. The instrument can be divided into two parts: sensor and electronic unit. The sensor uses a polarographic film-type dissolved oxygen electrode. The electronic unit is composed of high integrated circuits. The instrument uses a dot-matrix liquid crystal display to display dissolved oxygen values and temperatures.
