Dissolved oxygen tester

summary:

The dissolved oxygen tester (hereinafter referred to as the instrument) is mainly designed for the convenience of users to carry and operate on site. This instrument can be divided into two parts: sensors and electronic units. The sensor adopts a polarographic coated dissolved oxygen electrode. The electronic unit is composed of highly integrated circuits. The instrument adopts a dot matrix liquid crystal display, which can display the dissolved oxygen value and temperature.
