Panametrics, a Baker Hughes business, offersTunable Diode Laser Absorption Spectroscopy (TDLAS)to measure the moisture concentration in common gases. The Panametrics TDLAS portfolio, featuring theAurora product line, consists of industrial analyzers with intuitive interfaces and patented technology for superior performance.
These tunable diode laser analyzers are known for theirfast and accurate response, able toanalyze moisture from 2 to 5000 PPMv.Ourpatented calibration schemeallows for variations in background gas that would result in error conditions in other analyzers.
Requiring no regular recalibration,our TDLAS-equipped moisture analyzers offer our customers a low cost of ownership.
Aurora is available in these three configurations:
- Auroraprovidesimmediate responseto process upsets and quick dry down upon recovery.
- Aurora TransPortoffers TDLAS performance in arugged portable analyzer, whether onbattery or online power.
- Aurora 19is ideal for19-inch rack-mount installationsfor air, metrology, and heat-treating applications.
Our industrial TDLAS analyzer,Aurora, provides moisture measurementsfrom2 to 5000 PPM. Its accurate measurement technique措施moisture in many applicationssuch as natural gas TEG dehydration, natural gas storage, transmission and custody transfer, carbon dioxide for enhanced oil recovery and carbon sequestration, metal heat-treating furnace gases, and hydrogen recycle gas in reforming.

A portable industrial TDLAS analyzer, ourPanametrics Aurora TransPortdelivers reliability and accuracy anywhere. This on-the-go moisture analyzer rapidly responds to changes in moisture content in most gases. The unit is assembled intoa rugged and transportable case with a telescoping handle and wheels.
The TransPort isideal for spot-checkingthe performance ofnatural gas processing and drying systems, gas storage facilities, compression stations, refinery processes, heat-treating furnaces, instrument air, and more. It is ideally suited forfield verification of permanently installed moisture analyzers and transmitters. Features include:
Range
- Calibrated range: 0 to 5000 ppmv. For CO2 applications: 0 to 1000 ppmv
- Lower detection level: 2 ppmv (-71.7°C). For CO2 applications: 20 ppmv (-55.3°C)
- 露珠/霜点:过程/等效露水Point/Frost point calculation at user-defined constant pressure or external pressure specified by Modbus
Accuracy
- Parts per million by volume: ±1% of reading or ±2 ppmv , whichever is greater; for >1000 ppmv ±5% of reading
- For CO2 applications: ±3% of reading or ±5 ppmv. For H2 recycle applications: ±1% of reading or ±2 ppmv (for up to ±5% H2 and ±1% C2H6 variation from nominal calibration composition) (Individual instrument calibrated accuracy conditions provided in Certificate of Conformance. Accuracy of other parameters derived from ppmv.)
- Repeatability: ±0.2 ppmv or ±0.1%, whichever is greater. For CO2 applications: ±1.0 ppmv or ±0.5%, whichever is greater
- Operating sample cell pressure 10 to 25 psia (69 to 172 kPa)
Battery Life
- Rechargeable battery provides 8 to 10 hours of operation
