Introduction
The ESEGAS ESE-LASER-100P Portable TDLAS Gas Analyzer is designed for selective on-site measurement of trace gases in industrial emissions and process gas streams. Using Tunable Diode Laser Absorption Spectroscopy (TDLAS), it supports measurement of NH₃, HCl, and HF through their characteristic laser absorption wavelengths. The portable system integrates a gas analyzer, heated sampling line, and extendable sampling probe to maintain suitable sample conditions during field measurements. Its high selectivity, fast response, and resistance to background gas interference make it suitable for emission inspections, equipment commissioning, troubleshooting, and industrial gas concentration surveys.
