[Product Usage]
The SF-1 differential pressure method moisture tester is mainly used for the determination of trace moisture in 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 the problem of self assembling components in the laboratory, and draws on the advantages of imported machines in terms of structure, utilizing our company's scientific research strengths to ensure the accuracy of moisture determination and easy use.
[Instrument Characteristics]
The main features of SF-1 differential pressure moisture analyzer are: trace moisture such as polyester chips and nylon 6 particles after drying, which directly affects the spinning quality. At present, the main methods used for measuring trace moisture include differential pressure method, electrolysis method, Karl Fischer method, etc. Differential pressure method is fast, accurate, convenient, low-cost, and has a moderate instrument price, making it particularly suitable for factories and enterprises.
[Applicable Standards]
ISO6188-1980 "Plastics - Determination of moisture content in polyethylene terephthalate granules"; DIN EN ISO 960-1998 "Plastics Polyamide (PA) - Determination of moisture content "; GB/T 12006.2-1989 "Method for determination of moisture content in polyamides".
