  • Methane sensor type
    Dissolved CH4 molecules diffuse through a custom made thin film membrane into the internal gas circuit leading to a detector chamber, where the CH4 concentration is determined by means of Tunable Diode Laser Absorption Spectroscopy (TDLAS). Concentration dependent laser light intensities are converted into the output signal from calibration coefficients stored in firmware and data from additional sensors within the gas circuit.
