Aurora TransPort

Reliable, Portable Moisture Measurement
Panametric’s Aurora series of moisture analyzers uses
tunable diode laser absorption spectroscopy (TDLAS) torapidly and accurately measure moisture in a variety ofbackground gases. The Aurora TransPort, the latest addition
to the series, is a battery operated, moveable analyzer thatcan be taken into the field to directly measure moisture
content of natural gas and other process gases. The unit
is assembled into a rugged and transportable case with atelescoping handle and wheels.
Panametric’s patented temperature and pressurecompensated TDLAS provides repeatable, accurate anddrift-free moisture measurement with fast response.
The TransPort is ideal for spot checking the performanceof natural gas processing and drying systems, gas storage
facilities, compression stations, refinery processes, heat

treating furnaces, instrument air and more. It is ideallysuited for field verification of permanently installed moisture
analyzers and transmitters.
The unit is equipped with a rechargeable battery thatprovides 8 to 10 hours of operation as well as integrated
sample conditioning components. An easy-to-use display/
keypad enables direct display of moisture, temperatureand pressure. The unit also provides both analog (4-20 mA)
and digital interfaces (RS232/485 and Ethernet) for datarecording.
