System Description
The Series 2520 Portable Percent Oxygen Analyzer is a light-weight, easy-to-use analyzer that provides accurate and repeatable percent oxygen measurements in a variety of gases. The rugged and compact design of the Series 2520 makes it ideal for industrial applications where spot oxygen measurements need to be made. The Series 2520 can be configured with one of several measuring ranges from 0-1% to 0-99% oxygen. The standard Series 2520 Portable Percent Oxygen Analyzer is equipped with a 3-1/2 digit liquid crystal display, in-line filter, built-in NICAD batteries, and an AC adapter that provides the ability to recharge the NICAD batteries even while powering the analyzer from the adapter.

The Series 2520 Portable Percent Oxygen Analyzer features a patented, extended life oxygen sensor with EES (Enhanced Electrolyte System) that provides exceptional measurement accuracy and stability. For applications where carbon dioxide is present in the sample gas, the EES 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. The output from the sensor is temperature compensated.
