DOG-2082D Dual Channel Industrial Dissolved Oxygen Meter
DOG-2082D Dual
Channel Industrial Dissolved Oxygen Meter
DOG-2082D Industrial 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. Dual
channel dissolved oxygen meter, one instrument can connect 2 wastewater
dissolved oxygen electrode at the same time.
Features of
|
Complete English display, English menu operation: 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 time
|
|
and status can be
displayed on the screen at the same time. The main display can show the
oxygen concentration
|
|
value, hilite, far visual
range. Sub-displays can display such information as the input or output
current
|
|
temperature, status,
week, year, month, day, hour, minute and second etc, so as to adapt to
different users’ habits
|
|
and provide reference
times of instrument.
