Wastewater treatment processes that use aerobic bacteria to break down organic compounds in sewage and aquaculture operations require measuring dissolved oxygen (DO) to maintain effect ecosystems. For these and other applications that need to measure DO, Sensorex developed its DO6400 and DO6441 Process Dissolved Oxygen Sensors.
Both sensors use galvanic cell technology and a large volume electrolyte reservoir for long term continuous deployments and have a replaceable membrane. The membrane is available in either Teflon for durability or wide-span HDPE membrane for faster response.
The Model DO6441T Sensor offers a factory-calibrated 4-20 mA output for direct PLC interface. For applications with an external transmitter and a local display, the DO6400 Series is compatible with the Sensorex DO500 and DOMA 4-20 ma loop powered transmitters. The transmitter display can be programmed to read percent saturation, mg/mL or ppm DO.
