    Chapter 1. Features and capabilities Overview Panametrics’ Aurora H2O moisture analyzer for natural gas makes it possible for natural gas processing and transportation facilities to monitor moisture content in real-time with high precision and reliability. The Aurora H2O analyzer uses tunable diode laser absorption spectroscopy (TDLAS) to measure moisture in natural gas at the speed of light.

  • Page 12: Theory Of Operation

    Theory of operation The Panametrics Aurora H2O (tunable diode laser Since only light comes in contact with the sample of absorption spectroscopy) hygrometer for natural gas is natural gas, and all of the wetted materials are made a system designed to continuously monitor the moisture of non-corrosive and inert materials, this technology content in natural gas.
