El CS511 es una celda galvanica autopolarizada con compensacion automatica de la temperatura desde 4°C a 40°C. La sonda tiene una salida lineal en milivoltios la cual es proporcional al oxigeno presente en el mesurando. El rango de medicion es de 0 a 20 mg/l de oxigeno disuelto, una exactitud de ±2% de la lectura. El CS511 es fuerte y de bajo mantenimiento, fabricado por Sensorex.Read More
The CS511 consists of a self-polarizing galvanic cell that generates a millivolt signal proportional to the amount of oxygen present in the measured medium (typically water). Oxygen diffuses through its 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.
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.)
The CS511 manual has pictures of both the DO6400/T and DO6200/T, which can help you identify your sensor. Contact Campbell Scientific for more information.

Please note: The following shows notable compatibility information. It is not a comprehensive list of all compatible products.
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.

No. The cable is attached to the internal electronics. Removing them would be a violation of the warranty.
A standard reference table for dissolved oxygen in water/temperature/elevation is included.
Yes. This probe is completely submersible.
If the probe will be shelved for a month or more, the electrode should be removed. When the sensor will be used again, use fresh electrolyte and a new membrane. Following these guidelines will enable the probe to be stored indefinitely.
The CS511-L is a galvanic dissolved-oxygen probe that is designed to work in water. As O2 passes through the semipermeable membrane, the oxygen reacts with the electrolyte solution in the probe. As more oxygen becomes available, an electro-chemical process occurs, so that an increase in the mV output is recorded. The source of the oxygen can be through the air, water, or a liquid slurry. Soil is not very homogeneous, so the dissolved oxygen is not able to move freely.
