Online dissolved oxygen analyzer

DO-6800The Type Chinese Online Dissolved Oxygen Analyzer is an online intelligent dissolved oxygen detector produced by our company through the introduction of foreign technology. It uses imported components and dissolved oxygen film heads, based on the latest polarographic analysis technology, as well as advanced production processes and surface mounting technology. By utilizing this series of advanced analytical techniques,Ensure the long-term stability, reliability, and accuracy of the instrument. It has functions such as Chinese menu operation, notepad storage of measurement data, 485 communication, etc.It can be widely used for continuous monitoring of dissolved oxygen values in solutions such as chemical fertilizers, metallurgy, environmental water treatment engineering, pharmaceuticals, biochemistry, food, aquaculture, and tap water.

Key Features:

◇Large screen dot matrix LCD display, Chinese menu operation.

◇Simultaneous display of multiple parameters:Dissolved oxygen value, temperature, output current, alarm point, etc. are displayed simultaneously, which is intuitive and easy to read, and there is a range overrun prompt.

◇The screen displays an alarm status and can be accompanied by a switch at the same timeON/OFFSignal output.

◇Automatic temperature compensation function:automatic0～60℃.

◇Communication function (optional): equipped withRS-485Communication interface（MODBUSPartially compatible with the protocol),4～20 mACorresponding to current outputDOThe value can be set arbitrarily.

◇Notepad: capable of storing50Measurement data, users can record measurement data.

◇The hysteresis setting function can be set arbitrarily to avoid frequent actions of the switch relay.

◇Watchdog function: Ensure that the instrument panel does not crash.

◇The core components are all from foreign brands.

◇Factory settings can be restored. Power outage protectionProtection>10 years.
