ISO 11357 DSC Differential Scanning Calorimeter Thermal Analyzer Liquid Nitrogen Cooling
1. Product Introduction
LR-300 is the highest precision one among the DSC series products launched by our company, its sensor is E-couple with imported material, high precision, high sensitivity, good repeatability, the signal is protected by collector shielding, strong anti-interference, very high baseline stability and repeatability.
LR-300 Differential Scanning Calorimeter can be used for glass transition temperature, phase change temperature, melting point, enthalpy, curing temperature and product stability, oxidation susceptibility period and other tests. It is capable of performing research in the fields of tubing, polymer, chemical, food, medical, etc. It serves universities, enterprises, third-party measurement and quality inspection units, and has a wide range of applications to meet the testing needs of various industries.
2. Technical features
1. Industrial grade 7 inch touch screen, display rich information
2. New furnace structure, better baseline, higher precision. The heating method adopts indirect conduction method, which has high uniformity and stability, reduces pulse radiation, and is superior to the traditional heating method.
3. USB communication interface, strong commonality, reliable and uninterrupted communication, supports self-resuming connection function.
4. Automatic switching of two air flow, fast switching speed, short stability time. At the same time, a protective gas input is added.
5. Software is simple and easy to operate.
6. Ultra-high sensitivity, accuracy, 0.001 MW, 0.001ºC
7. The technical index is exquisite, the performance is superior, the price ratio is high, and the application is wide.
