TDLAS — BM-H-3 BeamStack Precision Photonics Features • • • • • • • Turnkey gas analyzer Absolute gas quantification Calibration-free gas analysis PPB-level sensitivity without cross-talks Digital and analog data interfaces IP68 grade mechanics Supply voltage: 15-32 VDC polarity protected Description The BM-H-3 BeamStack is a high-performance turnkey solution based on tunable diode laser absorption spectroscopy (TDLAS) for gas analysis. The analyzer is designed with user- and integration-friendliness in mind, suitable for both industrial settings with PLC systems and research laboratories, where raw and/or processed data can easily be exported and visualized for postprocessing in third-party tools. The robust and established TDLAS technology provides fast (100 µs) and highly sensitive (PPB-level) gas analysis. The TDLAS technology is also inherently self-referencing and calibration-free, requiring little to no maintenance. The analyzer can measure many common gases found in the industry and laboratories, including greenhouse gases such as methane (CH4). Other commonly analysed gases include O2, CO2, CO, N₂₂O, NH₃, NOx, HF, H2S and HCl, as well as hydrocarbons. The highly energy-efficient design allows the BM-H-3 BeamStack to run for hours on batteries, making it well-suited for mobile analyzer solutions at locations where there is no access to external power. The calibration-free gas analyzer system is highly durable for use in heavy industries and extremely robust in harsh environments.
