DOG-2082 Industrial online Dissolved Oxygen Meter is a kind of high-intelligence on line meter that is developed
by our company and used for continuous on line monitoring. It can be equipped with DOG-208F Polarographic
Electrode and can automatically switch from ppb level to ppm level of wide-range measurement. This instrument is
designed for monitoring the oxygen content in the boiler feed water, condensate water and sewage.
Features
English menu operation:
It has a complete English display and elegant interface: Liquid crystal display module with high resolution is
adopted.All the data, status and operation prompts are displayed in English.
Multi-parameter display: The oxygen concentration value, input current (or output current), temperature values,
time and status can be displayed on the screen at the same time. concentration value in a 10 x 10mm size.As the
main display is eye-catching, the displayed values can be seen from a long distance away. Six sub-displays can
display such information as the input or output current, temperature, status, week, year, day, hour, minute and
second, so as to adapt to different users' habits and to conform with different reference times set by the users.
