PRODUCT SHEET ACCURATE AND STABLE METHANE SENSOR FOR LONG-TERM DEPLOYMENT Dependable methane measurement for both pumped stationary systems (e.g., monitoring stations) or ship based underway systems (e.g. FerryBox). The CONTROS HydroC™ CH4 FT is a unique surface methane partial pressure sensor designed for flow through applications. HIGH ACCURACY AND STABILITY Due to their narrow line-width, the Tunable Diode Laser Detectors used in the Contros HydroC™ CH4 FT are accurate, with excellent methane molecule selectivity. Further, they feature a large dynamic range covering background partial pressures up to 40 matm. All detectors are subject to individual calibration and an in depth quality check in the -4H Jena QA lab before they are integrated into our sensors. The quality of the calibration is then verified individually in calibration tanks. The sensor is stable over extended periods as the detector tunes the laser to CH4 absorbing and non-absorbing wavelengths for each measurement, thus compensating for potential drift influences. OPERATING PRINCIPLE Water is pumped through the CONTROS HydroC™ CH4 sensor flow head and dissolved gases diffuse through the custom-made thin film TOUGH membrane into the internal gas circuit. This leads to a detection chamber where CH4 concentration is determined by means of Tunable Diode Laser Absorption Spectroscopy (TDLAS). Concentration dependent laser light intensities and additional gas circuit data are converted into an actionable, reliable output signal. SOFTWARE CONTROS DETECT® incl. real time data visualization, setting of sensor parameters (e.g. measuring intervals, internal data logger settings, sleep mode function) supported by a mission planning tool and data download from internal logger.
