Adiabatic SADT Tester
This instrument employs the Dewar flask adiabatic storage method to determine the self-accelerating decomposition temperature (SADT) of substances under simulated packaging conditions. The sample is loaded into a standard Dewar flask and maintained at a constant temperature in an adiabatic storage test furnace for 24 hours to observe whether self-heating occurs. By gradually adjusting isothermal conditions, the SADT is progressively determined, providing critical data support for temperature control, thermal safety assessment, and packaging selection of hazardous chemicals during storage and transport.
