Introduction: Liquid nitrogen refrigeration, the instrument through the flow of liquid nitrogen to achieve linear cooling, the minimum temperature can be reduced to minus 150 degrees. Differential Scanning Calorimetry (DSC), as a classical thermal analysis method for thermal effects at programmable temperature, is widely used in all kinds of materials and chemistry research and development, process optimization, quality control and failure analysis Occasion has long been widely used. Using the DSC method, we can study the phase transition of inorganic materials, the melting of polymer materials, the crystallization process, the polymorphism of drugs, the solid / liquid phase ratio of foods such as oil and fat. Meet the national standard GB / T2951.42-2008, GB / T15065-2009, GB / T17391-1998. Features: 1, industrial-grade widescreen touch structure, display rich information, including setting temperature, sample temperature, oxygen flow, nitrogen flow, differential heat signal, a variety of switch status. 2, by controlling the flow of liquid nitrogen to achieve linear cooling, the instrument can be linearly cooled to minus 120 degrees. 3, USB communication interface, versatility, reliable signal without interruption, support for self-recovery connection. 4, furnace structure is compact, adjustable heating rate can be adjusted. 5, to improve the installation process, all using mechanical fixation, completely avoid the body of the colloids of the differential thermal signal pollution. 6, dual temperature probe, to ensure high reproducibility of the sample temperature measurement. 7, the digital gas mass flow meter automatically switches two gas flow, switching speed, short stabilization time. 8, standard standard samples, to facilitate customers to correct the temperature coefficient. 9, the software adapts the computer screen resolution; support for notebooks, desktops, support WIN2000, XP, WIN7, WIN8, WIN10 and other operating systems. 10, to support the user self programming, measurement steps to achieve full automation. Software provides dozens of instructions, users can flexibly combine instructions according to their own measurement steps and save. Complex operation is simplified into one-click operation.
