Notes
1. This sensor contains an active charcoal filter and is consequently unsuitable for the measurement of combustible gases
and vapours other than methane and hydrogen.
2. For low temperature applications please refer to the MICROpeL application note.
3. Relative sensitivity data is intended for guidance only. For the most accurate measurements an instrument should be
calibrated using the gas under investigation.
N.B. Flow rate of 500 ml min-1. Conditions at 20A C, 50%RH, and 1013mBar unless otherwise noted.
Enhanced Features
a c Excellent shock resistance and reduced orientation effects
