MODEL 3020P Explosion Proof Percent Oxygen Analyzer

Teledyne’s Model 3020P Percent Oxygen Analyzer is a versatile microprocessor-based instrument for detecting oxygen at the percent (%) level in a variety of gases. This instrument serves as the explosion-proof, bulkhead-mount version of the 3000P, and is designed to make the task of percent oxygen analysis easier, faster and more precise than ever before. Simple menu choices, externally accessible switches and dual LCD and LED displays make set-up and operation clear and quick.

Three User-Configurable Analysis Ranges
Three user-configurable ranges are standard, with an excellent linearity precluding the need to recalibrate when changing ranges. Two fully programmable concentration alarms provide the versatility to satisfy nearly any requirement. All features offer a sophistication that assures the 3020P will provide years of service.

Convenient Outputs For Data
Two standard 0-1 VDC outputs provide concentration and range identification. A bi-directional RS-232 serial interface is incorporated to relay information to a host computer for remote monitoring of critical functions. Operator Interface All controls and displays on the standard 3020P are accessible from the front of the instruments. The instrument has two simple operator controls. A digital meter, an alphanumeric display, and a sample flowmeter give the operator constant feedback from the instrument.
