AT451 Differential Scanning Calorimeter (DSC) is used to determine and research the melting and crystallization process, glass transition temperature, oxidation induction time (OIT), reaction heat, heat enthalpy, melting point, phase transition, etc. This instrument complies with the following international and industry standards. ISO: ISO 11357. ASTM: ASTM E794. GB/T: GB/T 13464. Suitable for solid, powder and liquid samples, except gas samples. LCD display, touch screen operation. In-built atmosphere device, can simultaneously connect with Nitrogen and Oxygen, automatic switchover. With USB cable to connect the machine to the computer. The back of the machine. Main machine control and software control, friendly operation interface, easy to operate. With gas flow meter, accurate to control the gas flow. Small furnace, high accuracy of temperature control, the temperature can be RT~800℃. Also, liquid nitrogen cooling system can be optional, the temperature can be -100 ~ 800℃ or -20 ~ 600℃. Two user interfaces on software, one is for DSC test, the other is for OIT test. Real-time record and display DSC-Temp curve or DSC-time Temp-time curve. Fully equipped with accessories, convenient and easy to test. Chinese or English operation system can be selected.
