Process Dissolved Oxygen Sensors

The Sensorex line of Industrial Dissolved Oxygen probes are fast response galvanic sensors. They have a large reservoir of electrolyte and are 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 which 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).

DO Accessories and Replacement parts are readily available from stock. Complete membrane maintenance kits include everything you need to overhaul your DO sensor. Replacement membranes can be purchased in economical 5 or 25 count membrane packages and can be installed in just a few minutes.
