The Neutronics 1100 Percent Oxygen Analyzer is a compact analyzer for oxygen gas measurement and process control applications. Designed for a measurement range of zero to 100% oxygen, the unit features a reliable electrochemical sensor that can be mounted remotely at the sampling point to ensure a fast response time. A flow-through mounting head allows the sensor to be horizontally or vertically mounted directly into the sampled process gas stream.

The CAG-250E electrochemical sensor ensures reliable performance and fast response for critical measurements. Utilizing a patented weak-acid based technology for a more stable signal and longer sensor life, this sensor can withstand high levels of CO2, CO, and other acidic gases. The CAG-250E sensor measures the partial pressure of oxygen in the gas sample. As the sample gas passes by the sensor, the oxygen is electrochemically reduced at the cathode. The current generated is directly proportional to the partial pressure of oxygen at the sensing surface of the cell. The sensor is a sealed disposable device that does not require periodic maintenance.
