| Abstract: | Taking ARM S3C440B as the core, an instrument for measuring trace water based on Karl Fischer's method has been designed. The design method of the instrument is proposed, and the block diagram and controlled current-source as well as techniques for guaranteeing the measurement accuracy are given. |
