1. Product Introduction

The 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 polarographic analysis technology, as well as production process and surface mounting technology. Using this series of analytical techniques to ensure the long-term stability, reliability, and accuracy of the instrument. Featuring Chinese menu style operation and a notepad for storing measurement data、485 communication and other functions. 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.

2. Main 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 the alarm status and can be accompanied by ON/OFF signal output at the same time.

◇ Automatic temperature compensation function: automatic 0-60 ℃.

Communication function (optional): Equipped with RS-485 communication interface (partially compatible with MODBUS protocol), the DO value corresponding to 4-20 mA current output can be set arbitrarily.

◇ Notepad: capable of storing 50 measurement data, users can record measurement data.

◇ Function of setting hysteresis arbitrarily to avoid frequent operation of switch relays.

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

Imported core components.

◇ Factory settings can be restored, with power failure protection>10 years.
