  • Measuring principle


  • Product Headline

    Best-in-class gas analyzer for moisture (H2O) that is exceptionally reliable and tailored for the natural gas industry. The sensor measures gas using a tunable diode laser absorption spectroscopy (TDLAS) to determine the concentration of the gas without coming into physical contact with the stream. Heartbeat Technology ensures compliance and process safety at all times.
