In order to automatically verify the temperature parameters of the gas chromatograph, a new automatic temperature verification system is designed. This paper presents the composition and module design of the temperature data acquisition instrument. The Android mobile phone terminal application software by Java programming uses the Android Studio development environment and the serial communication technology, to realize the temperature measurement, paperless recording and automatically verification of the column box temperature stability and the program temperature repeatability of the gas chromatograph. Finally, the accuracy of the temperature data acquisition instrument is verified by the measurement calibration. The error of the indicated value in the measurement range is less than 0.3℃, which proves the feasibility of the design. Compared with the traditional method, the automatic temperature verification system of gas chromatograph designed in this paper improves the working efficiency and reduces the pressure and pressure for the verifier.
