The Model 3020P 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 setup and operation clear and quick.
Three user-configurable ranges are standard, with an excellent linearity precluding the need to recalibrate when changing ranges. Two fully programmable concentration alarms satisfy nearly any requirement. All features offer a sophistication that assures years of service.
Two standard 0-1 VDC and two 4-20 mADC isolated outputs provide both 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.
All controls and displays are available from outside the housing. The instrument has two simple operator controls. A digital meter, an alphanumeric display, and a sample flow meter give the operator constant feedback.
