Sensorex's Industrial Dissolved Oxygen Probes provide long life and low maintenance for reliable long term deployment for your waste water or aquaculture applications.

The Sensorex line of Industrial Dissolved Oxygen probes are fast response galvanic sensors.  They have a large reservoir of electrolyte and available with either mV or 4-20mA outputs.

Key features include: Large volume electrolyte reservoir for long term continuous deployments.  Sensors are available with either a durable teflon membrane, or a wide span HDPE membrane.   All models are available with an optional integral temperature sensor.  Calibration is easy, requiring only a single point air calibration.  

DO6400T probes are an excellent choice for aquaculture DO monitoring and control.  The DO6441T is also perfect for aquaculture applications, and now offers the user a factory calibrated 4-20mA output for direct PLC interface.   DO7400 series probes are best suited for applications in which DO level is below 0.5ppm (500ppb).  4-20mA versions of the DO7400 are also available (DO7441 - 0-100% sat and DO7442 - 0-200% sat).

Also available are DO Accessories, featuring maintenance kits,
