Qubit Systems provides a low level Methane Analyzer 0-100ppm that uses a sensor with a metal oxide semiconductor layer on an alumina substrate with integrated heater. The high resolution of the sensor (1ppm) allows detection of low levels of CH4 which is ideal in environmental applications. The Q-S127 CH4 Analyzer has an analog output of 0-5V and should be used with data interface and software. we recommend our C610 LabQuest Mini interface and Logger Pro Software
Data obtained from measurements of CH4 in water samples (200ml) taken from a beaver pond and placed in a 4L container to release methane into gas phase. First sample was taken from the bottom of the pond while stirring the muddy sediment. Second sample was taken from the pond without stirring of the sediment. Control samples are also included.
