How It Works?
Tunable Diode Laser Spectrometry (TDLS), enhanced by proprietary technology, is used for the measurement of CH4 and C2H6. SELMA Duo allows the measurement of target gas, based on contactless, near-infrared absorption. Self-contained modules have flow-through cells for extractive measurements. The proprietary lock-in technology and onboard digital signal processing unit run algorithms that compensate for drift phenomena, providing reliable and stable measurements for extended periods of time. SELMA Duo includes analog, digital data interfaces and digital output for state-of-the-art industrial connectivity.

FAQ
Honest answers to important questions
The presence of ethane in samples makes it possible to separate industrial leaks from natural biological. It reduces false search results
Laser radiation is completely safe, it corresponds to class 1.
Yes, the instrument works in all light and weather conditions
No, there is no impact.
No. The detector contains a reference cell with methane inside and calibration is performed at each start-up and during operation.
