The AOI Series 2500 oxygen transmitter is a loop-powered percent analyzer designed to provide 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 2500 features an extended-life oxygen sensor that provides exceptional performance, accuracy, and stability. For applications where carbon dioxide is present in the sample gas, the sensor retards passivation of the sensor anode by allowing the products of oxidation to dissolve in the electrolyte. In effect, the sensor is renewed continuously, resulting in an increase in sensor life even if exposed to 100% carbon dioxide. The enhanced mechanical design of the sensor ensures longer life, and virtually eliminates leakage of electrolyte. Optional equipment for the analyzer includes a sample filter, a pressure regulator, a flow meter, and explosion-proof housing.
