Product description

With built-in patented technology (ultra-low gas flow measurement), DC GPT is capable of monitoring the gas production behavior of the cell in real-time and in situ, including gas production and gas production rate and other parameters. Compared with the instrument based on the traditional Archimedes buoyancy method and the ideal gas equation of state calculation method, the device can directly monitor the micro volume change of gas. The results are accurate and reliable, with high repeatability. The exhaust gas can be directly collected, and the equipment can work tandemly with GC, DEMS and other gas analysis methods. DC-GPT provides real and reliable data for material research and development and analysis of gas production mechanism of lithium battery cells. It can also be used for sampling inspection on battery production lines.
