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 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. |
