O2 Online Process Analyzer – XLE 105-3

The Texas Analytical Controls’ Model XLE 302 Series O2 analyzers are extremely fast and accurate instruments for detecting and quantifying oxygen levels in process streams.  XLE302 Series employs advanced technology in every area of operation from the sensor to diagnostics.  The dedication to technological progress is the reason our analyzers are the lowest maintenance and most cost-effective line of analyzers available.

The analyzer will display “Sensor Weak” when the O2 sensor is 75% used.  This new feature provides the operator a warning to change the sensor.

A bump test can be performed to verify readings without removing the sample line.  This also saves the operator from completing a full calibration that takes 10 minutes.

Displays Historical Trend of O2 Readings within the previous hour

The display will read “Flow Fail.”  If the regulators and the flow meter(s) are not working properly and the sample to the analyzer is obstructed.

The SD memory card is used to store Historical Calibration and Alarm Data.  Each analyzer has the ability to be given a Name or ID.  The selected ID name will also be displayed when downloading data from SD card to a spreadsheet.
