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.
DO6200T probes are an excellent choice for aquaculture DO monitoring and control. The DO6242T is also perfect for aquaculture applications, and now offers the user a factory calibrated 4-20mA output for direct PLC interface.
Models DO7200 and DO7242 offer the same benefits as their DO6000 counterparts but offer better low end DO resolution for wastewater applications.
Also available are DO Accessories, featuring maintenance kits.
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.
