Digital Dissolved Oxygen Electrode D-HWS4551

Electrode Introduction

Ø Power and output isolation design to ensure electrical safety;

ØBuilt in protection circuits for power and communication chips, with strong anti-interference ability;

ØAdopting a comprehensive protection circuit design, it can work reliably without the need for additional isolation devices;

Ø The circuit is built inside the electrodes, with good environmental resistance and easier installation and operation;

Ø RS-485 transmission interface, MODBUS-RTU communication protocol, bidirectional communication, capable of receiving remote commands;

Ø The communication protocol is simple and practical, and extremely convenient to use;

Ø Output more electrode diagnostic information, more intelligent;

Ø Internally integrated memory, calibration and setting information can still be memorized even after power failure.
