Model 3000PA

Process Percent Oxygen Analyzer



The Model 3000PA brings percent oxygen analysis to new heights of precision. Using advanced microprocessor technology, this model makes the task of percent oxygen analysis easier, faster and more accurate than ever before. Simple menu choices, membrane command switches and a large LED display make setup and operation clear and quick.

Analysis Ranges

Three user-configurable ranges are standard, with excellent linearity of analysis precluding recalibration when changing ranges. Two fully programmable concentration alarms provide the versatility to satisfy nearly any requirement. All features offer next-generation engineering to assure it provides years of operational service.

Ambient Air Calibration

The high-accuracy and fast response is only surpassed by its ability to calibrate without the assistance of support gases. The Micro-fuel Cell produces an output that is linear from 0 ppm to 100% O2. enabling the use of ambient air for calibration.

Custom Engineering

This unit can be ordered as a standard unit or as part of a larger analytical system. Teledyne can also supply special sensors, custom engineered analyzers and complete monitoring systems to satisfy unique applications.

Outputs for Data

Standard 0-1 VDC outputs are provided for oxygen measurements and range identification. For two-way communication, an RS-232C serial interface is incorporated to converse with a host computer for remote monitoring and control of all functions. Configuration modifications and analysis results are as close as your computer.
