Application

DSC is an intelligent and miniaturized thermal analysis instrument, which is applicable for oxidation induction time(OIT) test, Oxidation induction temperature (dynamic OIT, also call OOT), as well as Glass transition temperature, Phase transition, Temperature and Enthalpy of melting and crystallization.

It provides an analysis method for organic, inorganic, polymer, mineral, petrochemical products, textile, medicine, etc. Functions like magnification and narrowing of the graph make the friendly interface easy to operate.

Features

1. Computer is introduced with rich information, e.g. temperature setting, sample temperature, Oxygen flow rate, Nitrogen flow rate, DSC signal etc.

2. Integrated furnace, user-selectable rate for temperature rising up/down.

3. Double temperature sensors ensure high repeatability of test results. One sensor installed on the wall of furnace, the other at the bottom of sample for collecting real test temperature. Patented controlling technology is applied to make the temperature of the sample reach to the set point by controlling the temperature on the wall of the furnace.

4. Digital mass-flow meter switches the flow rate of Oxygen/Nitrogen automatically with fast switching speed.

5. Standard sample provided for calibrating constant temperature coefficient.

6. Simplified to one-key operation. Tens of commands can be combined on your demands, making operation more easier. Also support self-programming function.

7. With standard material (indium, tin, zinc), users can adjust the temperature coefficient and enthalpy value coefficient by themselves.

8. The acquisition, storage and display of the data curve, result report including temp calibration and correction, extension of initial temp, enthalpy variables, glass transition temp, enthalpy change ratio (the reaction conversion), oxidation induction time(OIT), and the processing of dynamic parameters, etc.
