Uses for the sensors
– Emissions from open or closed-circuit respiration chambers
– Bio-gas monitoring
– Gas concentrations produced in-vitro
– Breath analysis, with a fast response and instant feedback, the sensors are optimal to measure fast changes in breath concentrations
– Emissions in exiting gas from barns or stables
– Concentrations in closed systems such as covered lagoons
Some of the advantages of the Methane and Carbon Dioxide sensors
– The sensors use the NDIR dual wavelength principle so the sensor is more stable and maintains calibration over long time periods
– The output signal is linearized
– Has an analog output signal or RS-485 interface
– Output signal is temperature and pressure compensated
– Is simple to integrate with other systems
The Methane sensors are available in many ranges, typically the 0-2% CH4 is used for breath analysis and 0-100% is used for in-vitro analysis.
The Carbon Dioxide sensors are available in two ranges, 0-10% is typically used for breath analysis and 0-100% is used for in-vitro analysis. Other ranges can be used depending on the application.
The linearity error is < 1% full scale (FS), the lower detection limit is < 0.5% FS, the repeatability at span is < 1% of FS, the long term stability is 2% of FS.
