Optical detector LaserGas™ III

gastunable laser absorption spectroscopy (TLAS)dynamic

NEO Monitors LaserGasTM is using Tunable Diode Laser Absorption Spectroscopy (TDLAS) 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. Features • Most advanced LaserGasTM technology available (3rd generation) • Portable (low weight) • Low power usage <10 Watt • Sub ppm HF detection • No interference from other gases • Stable calibration • No zero drift Applications The LaserGasTM III Portable HF Analyzer is the solution for reliable detection of short-term HF concentrations, wherever diffuse emissions occur representing a risk to the work force. Focused applications are: • Aluminium smelters: Worker protectioduring active work • Aluminium smelters: Mapping plant emissions • Refinery alkylation plants: Worker safety Customer benefits • Flexible unit designed for measurement on the spot • Allows fast and reliable operation to measure sub ppm and several hundred ppm HF concentrations • Regular maintenance not required • No cross interference from other gases • Short-term HF peaks are uncovered with the LaserGasTM III portable • Easy to carry • Battery operated for several hours • Internal storage of data
