The AOI Series 3500 oxygen transmitter is a loop-powered analyzer designed to provide trace oxygen measurements in a variety of background gases. The transmitter's enclosure is made from durable polycarbonate. The 4-20 mADC output can be used with a data logger, recorder, programmable logic controller, or digital control system.
The Series 3500 features an ambient-temperature electrochemical sensor. The enhanced mechanical design of the sensor ensures longer life, and virtually eliminates leakage of caustic electrolyte. The sealed sensor is not position-sensitive and does not require manual adjustment based on changes in the molecular weights of sample gases such as helium and hydrogen. The output from the sensor is both linear and temperature-compensated to provide optimum performance.
An optional CO2-tolerant trace oxygen sensor is capable of providing accurate oxygen readings in gases containing up to 100% CO2 without shortening the life of the sensor.
