Abstract The uncertainty analysis of the FPG8601 gas piston pressure gauge is taken in the gauge mode in this paper. The obtained result of the FPG8601 gas piston pressure gauge uncertainty is 30ppm. Based on the FPG8601 gas piston pressure gauge uncertainty analysis, test had been taken for verifying the uncertainty result of FPG8601 with comparison method to primary standard, the analysis result is confirmed by the test.
