Watch this full walkthrough of the SH128C Automatic Jet Fuel Freezing Point Analyzer, built to ASTM D2386 and GB/T 2430. We demonstrate the 7-inch touch screen workflow, dual automatic stirring, fiber-optic freezing point detection, and the +30℃ to -70℃ cascade refrigeration system in action. See how the unit automatically tracks crystal disappearance temperature, stores results, and prints reports — giving B2B lab teams a clear look at real testing performance and efficiency.
