GE PANAMETRICS : AURORA

AURORA features:

• Range 0-400 ppmv
• Lower Detection Level: 50 ppbv (parts per billion)
• Utilizes many of the same design features of the Aurora-H20 including:  Electronics enclosure, display, user interface
• cFMus Class 1 Div1 certification for the USA & Canada, ATEX & IEC Ex for Europe and other global localities
• Programmable 4-20mA signal.  RS-232/485 digital interface with Modbus & Foundation Fieldbus option
• AuroraView – Utility software for remote set up, trend graphing & diagnostics
• Optional calibration system –  may be programmed to run on demand or at a specific time (Regen Time)
• “Multi Pass Optical Cell (specially curved mirrors)”:  To measure trace levels of moisture (<5 ppmv)  a long path length is required.   In the Aurora Trace the path-length is 30 meters vs. 1 meter for Aurora H2O resulting in 30X the sensitivity.   
• Utilization of a vacuum cell is a time proven method of producing a high resolution signal.   Analyzers using this method have been applied to semiconductor and air separation industry.   
• The GE-Aurora-Trace is the 1st analyzer to apply this technique to a rugged explosion proof system
• The signal at trace level moisture concentrations (<5 ppmv) is 5X that of TDLAS system operating at atmospheric pressure. 
• ZERO-CALIBRATION for 5 years !
