TDLAS – BM-H-3 with BeamCell


The BM-H-3 with BeamCell is a high-performance turnkey solution based on tuneable diode laser absorption spectroscopy (TDLAS) for analysis of extracted/sampled gas.

By extracting gas in a parallel flow for analysis in the controlled atmosphere of the BeamCell, very high measurement accuracy can be achieved.

The system can be placed in a cabinet that is easily accessible, out of explosion zones, and with our “FFCB-1 Safety Control” it is possible to monitor temperature, gas flow and ventilation in the cabinet to trigger an alarm if something malfunctions that can generate an explosion risk.

The system is designed with user-friendliness in mind, both for integration in industrial settings and in research laboratories, where raw data and/or processed data can be easily exported and visualized for post-processing in Matlab, Excel, Python or similar.

The robust and established TDLAS technology provides fast (50 µs) and highly sensitive (PPB-levels) gas analysis.

The TDLAS technology is also inherently self-referencing and calibration-free, requiring little to no maintenance.

The system can measure many common gases found in the industry and laboratories, and greenhouse gases such as methane (CH4). Other commonly analysed gases include O2, CO2, CO, NOx, SOx, HF, H2S, NH3 and HCl, as well as hydrocarbons.

The highly energy-efficient design allows the BM-H-3 to run for hours on batteries, thus being well suited of providing mobile remote sensing at locations where there is no access to external power. It can also relay information wirelessly.

The calibration-free gas detection system is highly durable for use in heavy industries and extremely robust to harsh environments.
