SPTr-GAS Photoacoustic Trace Gas Analyzer ultra low concentration trace gas detector

SPTr-GAS Photoacoustic Trace Gas Analyzer

Brief introduction

Thanks to their sensitivity and stability the SPTr- GAS® Analyzer with Photoacoustics technology are particularly well suited for detecting trace elements as e.g. HF in waste combustion, SO2 in ambient air , NH3 measurement in industry processing and so on. A number of other gases can be quantitatively detected based on the modular concept of the gas sensor.
