The main technical performance is as follows：

1: The image of the test sample is captured by a CCD camera and displayed on the computer screen. During the heating process, all changes in the contour of the sample can be observed through a computer screen;

2: Temperature measurement range: 0 ℃~1550 ℃, long-term use temperature below 1450 ℃;

3: Temperature measurement accuracy: ± 0.2% (full scale);

4: Temperature resolution: ± 1 ℃;

5: The heating furnace is a platinum rhodium wire furnace (with rhodium accounting for 30%), and the diameter of the platinum rhodium wire is 0 8mm, capable of heating up to 1550 ℃; Molybdenum wire can also be used (in a protective atmosphere), with a maximum temperature of 1750 ℃.

6: The heating is controlled by a microprocessor program, and the temperature control thermocouple is an S-type thermocouple placed inside the furnace wall and led out by a terminal. The temperature control process is determined by the temperature control curve set in advance on the temperature controller, and can also be manually controlled;

7: The lighting source adopts 6V, 30W instrument lights with adjustable brightness; Or fixed brightness.

8: The temperature control system is centralized in the temperature control chassis, with a power supply of single-phase 220V and a frequency of 50Hz;

9: The instrument is equipped with over temperature protection and over current protection.

10Used for analyzing the interface contact angle of different materials under different temperature conditions, completed by a computer program for analysis and processing.
