（China）YY174 Air Bath Heat Shrinkage Tester
Principle of the instrument:
The tested sample is placed in the displacement and force test area, rapidly heated to the shrinkage temperature, and then cooled. The system records the shrinkage force, temperature, shrinkage rate and other parameters in real time and automatically, and analyzes the measurement results.
Instruments features:
1.Innovative laser measurement technology accuracy and efficiency upgrade:
1) Using advanced laser measurement technology, non-contact accurate measurement of film thermal shrinkage.
2) Brand high-precision force value sensor, providing better than 0.5 force measurement accuracy, heat shrinkage force and other performance test repeatability, multi-range selection, more flexible testing.
3) Brand operation control system to provide accurate displacement and speed accuracy.
4) The sample into the warehouse speed is optional in three levels, the fastest up to 2 seconds.
5) The system displays the thermal shrinkage force, cold shrinkage force and thermal shrinkage rate during the test in real time.
2.High-end embedded computer system platform safe and easy to use:
1) Provide historical data query, print function, intuitive display results.
2) Embedded USB interface and network port to facilitate external access and data transmission of the system.
