Pressure wireless data recorder is widely used in medical,food,medicine,biotechnology and other fields as the verification equipment of thermal sterilization effect.Because the accuracy of its quantity value will di-rectly affect the effectiveness of sterilization,the calibration is mainly carried out at room temperature in China at present,which is quite different from the actual use environment of more than 100℃.Therefore,according to JJF 2095-2024 calibration specification,this paper conducts comparative experiments on different pressure values at normal temperature,121 ℃ and 134℃.The results show that the pressure value of the recorder at normal tempera-ture is very different from that at 121℃ and 134℃,that is,the ambient temperature has a great influence on the measurement results.
