- 2-wire compact liquid analytical DO (dissolved oxygen) transmitter
- DO measuring range: depending on the applied sensor: 10 ppm or 20 ppm
Our DO6440 series of galvanic dissolved oxygen sensors deliver accurate measurements with very fast response time. Calibration is simple and only requires a single-point air calibration. Sensor directly outputs a 4-20mA signal scaled to the sensor range for easy PLC integration.
