CS511-L Dissolved Oxygen Sensor

Oxygen diffuses through the CS511’s membrane onto a cathode that produces a chemical reaction. An electrical current is produced by this reaction, which is converted from microamps to millivolts by an in-line resistor. An in-line thermistor provides automatic temperature compensation. 

Because the CS511 is shipped dry, DO electrolyte needs to be added before using the sensor. DO electrolyte as well as spare membranes are included in the sensor’s shipping kit. 

Currently, the CS511 is Sensorex’s Model DO6400/T. Prior to June 2008, the CS511 was Sensorex’s Model DO6200/T. Programming, wiring, and most specifications are the same for these two sensors. However, they use different accessories and look different. Replacement parts remain available for the older DO6200/T. (See the Ordering Info on the web page.)
