Abstract：Designed a water dew-point instrument, which can control the whole measurement progress by computer. This paper researched the fundamental principle of water dew-point instrument, and discussed the hardware structure and the technological process of software of the system. The instrument is composed of a power supply host, a semiconductor refrigeration chip assembly which is connected with a power supply host through a conducting wire, a temperature pressure detection and an industrial camera. The use of digital images to replace the naked eye to determine the basis for the measurement of water dew point.
Key words：natural gas；water grain；digital image
