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.

Technical parameters:

Dot matrix backlight LCD display

Automatic temperature compensation, fast response time

Portable, easy to carry

Equipped with our dissolved oxygen electrode (polarographic film-coated)
