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).
Dissolved Oxygen probe Membrane Kits are used for routine maintenance of DO sensors and are available for DO-6000 and DO-7000 series sensors with Teflon or HDPE membranes. All kits include 500 mL electrolyte, DO membrane removal tool, 1 O-ring body seal and 5 replacement membranes and membrane O-rings.
Membranes and O-rings are also available separately in 5 or 25 count packages. DO electrolyte can also be purchased separately in 500mL bottles.
