Description
technical field [0001] The invention belongs to the technical field of oil quality analysis, and in particular relates to a mobile oil micromoisture monitoring device and a monitoring method thereof. Background technique [0002] The determination of trace moisture in oil is one of the most important indicators in oil performance testing. Under normal circumstances, there are two methods for the determination of trace moisture in oil, on-line and offline. Now most of the petroleum industry and power industry use offline measurement methods. Offline monitoring has the disadvantages of long analysis time and many influencing factors. The existing online moisture measuring instrument has a high analytical range, but low measurement accuracy and high detection limit, and cannot accurately measure milligram level or even microgram level trace moisture in oil, and cannot process and timely measure oil with excessive moisture content. Call the police. Contents of the invention ...
