Industrial online dissolved oxygen analyzer DO-100

Application field

Widely used for online monitoring of dissolved oxygen in thermal power, chemical industry, metallurgy, water treatment, pharmaceuticals, biochemistry, electronics, electroplating, printing and dyeing, chemistry, food, and tap water.

Instrument features

DO-100 is our company's new highly intelligent all Chinese and English microcomputer based dissolved oxygen controller

※ LCD large screen display, full Chinese menu operation, human-machine dialogue, microcomputer operation

Display DO value, output current (or electrode current), temperature, time, and status on the same screen.

Using the latest components, the dual high impedance input impedance is as high as 1012 Ω, with strong anti-interference ability.

The current output adopts photoelectric coupling isolation technology, which has strong anti-interference ability and can be transmitted remotely.

The optional communication interface allows for easy connection to a computer for monitoring and communication

Automatically achieve wide range measurement from ppb level to ppm level
