Analysis of measuring performance of 10 kPa gas piston manometer

In this paper, the measurement performance of a 10 kPa gas piston manometer is analyzed. First, we introduce the working principle and structure of the gas piston manometer. Then, we discuss in detail the accuracy, repeatability, sensitivity, and stability of the manometer. We found that the 10 kPa gas piston manometer has a high accuracy. The manometer shows good repeatability, that is, the results obtained by multiple measurements under the same conditions are very close. The manometer is very sensitive to pressure changes in a small range and can provide accurate measurement results. The pressure gauge shows good stability, that is, it can maintain relatively stable measurement results during long-term use. The 10 kPa gas piston manometer is suitable for various pressure measurement occasions.
