Sensorex dissolved oxygen sensor

Sensorex DO6400 Sensor

The DO6400 series galvanic dissolved oxygen sensor delivers accurate measurements with very fast response time.

Calibration is simple and only requires a single-point air calibration, and its large electrolyte reservoir decreases downtime due to maintenance. This dissolved oxygen sensor directly outputs a Millivolt, 4-20mA analog or MODBUS/RS485 digital signal scaled to the sensor range for easy PLC integration.


  • Fast response time: Galvanic sensor technology delivers accurate dissolved oxygen monitoring
  • Simple system integration: Uses direct Millivolt, 4-20mA analog or MODBUS/RS485 digital output signal to integrate with a PLC or other control system
  • Input Voltage Options:
  • 12V DC – MODBUS only
  • 24V DC – 4-20mA & MODBUS
  • Infrequent, easy maintenance: Large electrolyte reservoir facilitates long-term sensor deployment
  • One year limited warranty


Typical applications

The Sensorex DO6400 sensor is ideal for aquaculture and wastewater monitoring applications.
