Overview

The DO6400 Dissolved Oxygen Sensor from Sensorex is engineered for reliable measurement of dissolved oxygen in a variety of water applications such as aquaculture, wastewater treatment, and environmental monitoring. This galvanic sensor uses proven technology to deliver accurate readings with minimal latency, and its large electrolyte reservoir reduces maintenance frequency. Calibration is straightforward with a single-point air method.

Users can choose between multiple communication outputs to suit different control and data acquisition needs, including traditional analog signals (millivolt or 4–20 mA) or digital data via MODBUS/RS485. The sensor operates within a broad temperature range and supports multiple saturation ranges. Its robust construction with chemically resistant materials and extended cable make it suitable for long-term deployment in demanding environments. Sensorex offers a one year limited warranty on this sensor.
