Principle
Differential Scanning Calorimeter analyzes the thermal performance of the material by measuring the difference in heat flow between the sample and the reference under programmed temperature control. PID is used to precisely control the fully automatic temperature control program, and the Sensor is based on the thermal diffusion process to ensure accurate data collection.
Applications
Pipe, polymer, chemical, food
Standards
GB/T 33466.1-2016、GB/T 40271-2021、GB/T 19466.1-2004、GB/T 19466.4-2016、GB/T 19466.5-2022、GB/T 19466.6-2009、GB/T 19466.2-2004、GB/T 19466.3-2004、GB/T 29611-2013
Steps
1. Set up the initial atmosphere evacuation of the experiment, including the exhaust time of the inert gas
2. Set program parameters through instrument interface or software, including temperature range, heating rate, etc
3. Start the automatic operation test of the instrument
4. The software automatically analyzes the data and exports the results in EXECL or PDF format
5. Optional master standard comparison, set the error value for qualification judgment
Notice
• Ensure that the atmosphere device is connected correctly to avoid gas leakage
• Consider environment and power conditions when setting PID parameters
• Chill down Air-Cooled to ensure well ventilated
• The data collection frequency can be set by yourself, the range is 0.1~ 50Hz
• Exceeding the error value in the comparison function will prompt unqualified, so pay attention to setting reasonable errors
