DOT3200 Online Dissolved Oxygen Meter

As shown in the figure:

● Fully intelligent, featuring high-precision AD conversion and microcontroller-based processing technology for powerful functionality

● High reliability: components are integrated onto a single circuit board, eliminating the need for complex function switches and potentiometers

● Strong anti-interference capability and excellent electromagnetic compatibility

● Automatic range switching within the measurement range covered by the Sensor

● Phase-sensitive detection: Eliminates the influence of lead wires on concentration measurement

● 4–20 mA current output, or RS485 output

● Standard IP65 waterproof body design

● Can be installed on dials, pipelines, and walls
