◆ SF-1 type differential pressure method micro-moisture analyzer main features: after drying, polyester chips, nylon 6 particles and other micro-moisture directly affect the spinning quality. At present, the main methods used for the determination of trace moisture are differential pressure method, electrolysis method, Karl Fischer method, etc. The differential pressure method is fast, accurate, convenient, low-cost, and moderate in instrument prices, and is especially suitable for factories and enterprises.
◆ SF-1 differential pressure method trace moisture analyzer, mainly used for the determination of trace moisture of polyester chips and nylon 6 particles in the chemical fiber and plastic industries before melt spinning and after drying treatment. The development of this instrument solves In the current laboratory, the trouble of self-preparation and self-assembly of components is required, and the advantages of imported machines are absorbed in the structure, and the company's scientific research strengths are used to ensure the accuracy of moisture determination and convenient use.
