Aurora 19

Reliable moisturemeasurement
Panametrics Aurora 19 analyzer uses tunable diode laser
absorption spectroscopy (TDLAS) to accurately measuremoisture in a variety of background gases. The Aurora 19
analyzer is suitable for installation in safe areas and operates
over a wide range of environmental conditions. Aurora 19’s fast
response immediately alerts when moisture concentrations areout of compliance; once corrected, gas can be quickly cleared
for process normalization.
The Aurora 19 analyzers have an intuitive interface that makes
them easy to learn, configure and operate. With a local service
team to support them, you have the confidence of knowing that
Aurora 19 analyzers are always ready for immediate moisturemeasurement. With power and gas lines easily connected, theAurora 19 moisture analyzer provides a wide range of reliablemeasurement with accuracy and fast response you need for
immediate alerts to process upsets or out-of-compliancemoisture concentrations.
