The air specific heat capacity ratio tester is a new type of experimental instrument based on the original air specific heat capacity ratio tester used in general physics experiments. It uses diffused silicon pressure sensor to measure gas pressure and integrated temperature sensor to measure temperature. The accuracy and sensitivity of measuring gas pressure and temperature are higher. It can more obviously observe thermodynamic phenomena, and the measured air specific heat capacity ratio is consistent with the measured temperature Compared with the standard value, the error is within 3%. At the same time, students can also learn the principle and application of advanced silicon pressure sensor and semiconductor integrated temperature sensor, which greatly enriches the teaching content and is worthy of popularization and application in general physics experiments in Colleges and universities.
