ISO 11357 Calorimeter DSC Differential Scanning Calorimeter Differential Scanning Calorimetry Test
1. Product Introduction
LR-300 is the company launched DSC series of products with the highest accuracy of one, the sensor is the use of imported material E-couple, high precision, high sensitivity, good repeatability, signal acquisition circuit shielding protection, strong anti-interference, baseline stability and repeatability is very high.
LR-300 differential scanning calorimeter, can be glass transition temperature, phase transition temperature, melting point, enthalpy value, curing temperature and product stability, oxidation induction period and other tests. It is qualified for the research of pipe, polymer, chemical, food, medical and other fields, and serves universities, enterprises, third-party measurement and quality inspection units, with 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 body structure, better baseline, higher accuracy. Heating adopts indirect conduction mode, high uniformity and stability, reduce pulse radiation, better than the traditional heating mode.
3.USB communication interface, strong commonality, reliable communication without interruption, support self-recovery 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. Exquisite technical indicators, superior performance, cost-effective, widely used.
