Model 3000TA

Process Trace Oxygen Analyzer



 Description

The Model 3000TA makes the task of trace oxygen analysis easier, faster and more precise than ever before. Simple menu choices, membrane command switches and a large LED display make setup and operation clear and quick.


Air Calibration

The high-accuracy and fast response of this model is only surpassed by its ability to calibrate without the assistance of support gases. The Micro-fuel Cell produces and output that is linear and enables the use of ambient air for calibration. The model also accommodates the use of a certified ppm O2 span or zero gas which speeds calibration when necessary and confirms the system is leak free.


User-Configurable Ranges​

Three user-configurable ranges are come standard with this model. When changing ranges, you are provided with excellent linearity of analysis precluding recalibration. Two programmable concentration alarms will provide the versatility to satisfy nearly any  requirement.


Custom Engineering

The 3000TA can be ordered as a standard unit or as part of a larger analytical system. The options for this model are as follows.

  • C: Auto cal/zero with integrally mounted control valves

  • V: Vacuum service

  • K: 19” rack mount with either one or two control units

  • S: Stainless steel cell block

In addition, special sensors, custom engineered analyzers and complete monitoring systems can be suppled to satisfy unique applications.


Maintenance-Free

The model uses a specifically qualified fast recovery InstaTrace Micro-fuel Cell to measure trace levels of O2 in the sample gas. This sensor sets industry standards for accuracy, sensitivity and ease of use. The InstaTrace is a sealed electrochemical device with no electrolyte to charge or electrodes to clean, making it maintenance-free.


Convenient Outputs

The standard 0-1 VDC and isolated 4-20 mADC outputs are provided for oxygen measurements and range identification. For 2 way communication, an RS-232C serial interface is incorporated to converse with a host computer for remote monitoring and control of zero and span calibration.
