Gas analyzer Aurora 19

processmoistureportable

Panametrics Aurora 19 analyzer uses tunable diode laser absorption spectroscopy (TDLAS) to accurately measure moisture in a variety of background gases. The Aurora 19 industrial moisture analyzer is suitable for installation in safe areas and operates over a wide range of environmental conditions. The Aurora 19’s fast response immediately alerts when moisture concentrations are out of compliance; once corrected, gas can be quickly cleared for process normalization.
