DOG-2082 Industrial online Dissolved Oxygen Meter
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 sewae.
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.
