An experimental system for the measurement of the temperature coefficient of Platinum resistance was designed base on NI USB-6210 data acquisition card and LabVIEW．The system could record and display the change of temperature vs output voltage of unbalanced bridge in real-time． Multi experimental curves of different parameters could be displayed simultaneously，which could help us to slope of the calibration curve．The experimental results show that the proposed system makes the process of measurement intuitive and accurate，and it can better meet the requirements of scientific research test and teaching experiment．
