DSC-500BL Differential Scanning Calorimeter for food packaging and technical textiles

Summary

It is touch screen type, differential scanning calorimeter can be tested glass transition temperature, phase transformation, melting and heat enthalpy testing, product stability, oxidation induction period test. Instrument conforms to the national standard GB/T 19466.2-2004 / ISO 11357-2:1999 part 2: determination of the glass transition temperature, GB/T 19466.3-2004 / ISO 2004-3:1999 part 3: determination of the melting and crystallization temperature and heat enthalpy.

Technical characteristics

widescreen touch structure of industrial level, rich display information, including the set temperature, sample temperature, oxygen flow rate, Nitrogen flow, differential thermal signals, all kinds of switch state, the flow rate to zero.

USB communication interface, strong commonality, reliable communication don't interrupt, support the restore the connection.

furnace structure is compact, arbitrary adjustable cooling rate.

l improve the installation process, all adopt mechanical fixed way, completely avoid the furnace internal colloid pollution of the differential thermal signal.

l furnace heating with heating wire heating, furnace cooling adopts electronic semiconductor refrigeration method, compact structure, small volume. Without external cold source and tedious refrigeration auxiliary system, temperature and cooling speed, the lowest refrigeration temperature can reach to 20 ℃

l double temperature probe, make sure the height of the sample temperature measurement repeatability. Temperature sensor installed on the furnace wall, all the way to the PID control of the furnace temperature, but due to the temperature of thermal inertia, conduction to the temperature of the sample on a certain deviation, and deviation degree of chun xiaqiu winter is different, therefore, adopt single temperature probe temperature control and temperature measuring, differential thermal signals and temperature signals, error is large; The instrument in the samples at the bottom of the installation of a temperature sensor, used to measure the real temperature of the sample, and we use special temperature control technology, control the temperature of furnace wall temperature to reach the set temperature.

l digital gas mass flowmeter atmosphere flow switch two road, switching speed, stable time is short.

l with standard samples, convenient customer constant temperature correction coefficient.

The software adaptive resolution computer screen, the software automatically according to the computer display screen size to adjust the curve. Support notebooks, desktops; Support the Win2000, XP, VISTA, Windows 7 operating system.
