【C09】Gas Concentration Measurement System for Low Carbon Fuels

Calibrated Device 
Special Concentration in Synthetic Natural Gas
The concentration of the gas to be calibrated is verified by using a synthetic natural standard gas with metrological traceability.  The concentration of the executable verification is based on the concentration range of natural gas standards that the laboratory has.  The main component gas with a concentration greater than 1% can be verified to a concentration between 1/2 to 2 times of the standard gas concentration.
Uncertainty   0.2 % to 1.2 %
