Model 3000TB​​​

Process Trace Oxygen Analyzer​​​



 Description

The Model 3000TB analyzer is a versatile, microprocessor-based instrument for detecting oxygen in a variety of gases. It serves as a general purpose unit.


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.


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.


Maintenance-Free

The instruments use a long life Micro-fuel Cell to measure traces of O2 in the sample gas. The sensor sets industry standards for accuracy and sensitivity, and comes with a 1 year warranty. Expected life for the sensor is two years. The sensor is specific to oxygen and accurately monitors gas streams containing up to 100% hydrocarbons. The Micro-fuel Cell produces an output that is linear from 0 ppm to 100% O2 enabling the use of ambient air for calibration. These units can also accommodate the use of a certified ppm O2 span or zero gas which speed calibration when necessary.
