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 0-100% 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.
