Model 3010TA​

Process Trace Oxygen Analyzer​​​


The Model 3000TA is a versatile microprocessor-based instrument for detecting oxygen at the parts-per-million (ppm) level in a variety of gases.

Three Analysis Range

Three user-configurable ranges are standard, with excellent linearity precluding recalibration when changing ranges. Two fully programmable concentration alarms and relay functions provides the versatility to satisfy nearly any requirement. All features offer a sophistication that assure years of reliable service.

Split Architecture

This unit is designed as a “split architecture” instrument. It is a general purpose, wall mounted  control unit for non- hazardous areas  that controls an analysis unit or “remote probe” that can operate in hazardous areas. Simple menu choices, membrane command switches, and dual LCD and  LED displays make setup and operation clear and quick.

Convenient Outputs

Standard 0-1 VDC and isolated 4-20 mADC outputs are provided for oxygen measurements and range identification. An RS-232C serial port allows the user to introduce span and zero gases through a host computer.
