Versatile Differential Scanning Calorimeter for Analysis of Polymer Melting Point and Phase Transition Temperature

Specification:

1. Display System

2. Communication Interface

3. Furnace Structure

• The furnace body adopts a compact design with stepless adjustable heating rate, flexibly meeting diverse temperature-rise demands for different test scenarios.
• The installation process is optimized with a full mechanical fixing method, which completely eliminates the risk of colloid inside the furnace interfering with the differential thermal signal—effectively ensuring the accuracy of test data.

4. Dual Temperature Probe Design

• A temperature probe mounted on the furnace wall is used for PID control of the overall furnace temperature. However, thermal inertia causes a certain deviation between the furnace wall temperature and the actual sample temperature, and this deviation varies with seasons.
• To resolve this issue, an additional temperature probe is installed at the bottom of the sample to measure its real-time actual temperature. Combined with our proprietary temperature control technology, the furnace wall temperature is precisely regulated to make the sample temperature reach the set value—significantly reducing errors in both differential thermal signals and temperature data.

5. Gas Atmosphere Control

6. Calibration & Cooling Functions

• Standard samples are provided to facilitate customers' calibration of temperature coefficients, simplifying routine verification operations.
• A dedicated furnace cooling interface is designed to support rapid furnace cooling, shortening the interval between consecutive tests and improving work efficiency.

7. Software Performance

The software adapts to computer screens of various resolutions, automatically adjusting the curve display mode according to the screen size. It is compatible with both laptops and desktops, and supports operating systems such as Win2000, XP, VISTA, and WIN7.

It supports user-programmable protocols to realize automated test procedures. The software offers dozens of instructions, allowing users to flexibly combine and save instructions based on their specific test steps—simplifying complex operations into one-key operations.
