Dissolved oxygen tester

Overview:

The dissolved oxygen tester (hereinafter referred to as the instrument) is mainly designed for users to carry it to the site for operation. The instrument can be divided into two parts: sensor and electronic unit. The sensor adopts polarographic film-coated dissolved oxygen electrode. The electronic unit is composed of high integrated circuits. The instrument adopts dot matrix liquid crystal display, which can display dissolved oxygen value and temperature.
