DO-3082 Industrial online Dissolved Oxygen Meter is our latest generation of microprocessor-based high-intelligence on line meter, with English display, menu operation, a high intelligent, multi-function,
high measurement performance, environmental adaptability and other characteristics, used for continuous
on line monitoring. It can be equipped with DO-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
New design, Aluminium shell, Metal texture.

All the data are displayed in English. It can be easily operated:

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. There is no symbol or code that is

defined by the manufacturer.

Simple menu structure and text-type man-instrument interaction: Compared with traditional instruments,

DO-3082 has many new functions. As it adopts classified menu structure, which is similar to that of a computer,

it is clearer and more convenient. It is not necessary to remember the operation procedures and sequences. It can

be operated according to the prompts on the screen without the guidance of an operation manual.

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. The main display can show the oxygen

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.
