Analyzer LaserGas™ III Portable HF


NEO Monitors LaserGasTM is using Tunable Laser Absorption Spectroscopy (TLAS) i.e. a non-contact optical measurement method employing solid-state laser sources. The portable analyzer is compact, lightweight, and battery powered for HF measurement on the spot. With onboard pump and connections for Teflon tubing the target gas is continuously transferred into the internal measurement cell. The instrument´s low power design gives long operating time on each battery cycle.
