1、自主开发了新型刚性支架结构，使得试验结果更加准确，性能大大优于ASTM C1698标准，刚性支架结构目前已申请专利；
2、可根据用户要求定制波纹管尺寸，并对应加工适合的刚性支架；
3、测试通道可根据用户需要定制，有3通道、6通道、9通道和12通道可选；还可根据用户需求定制更多通道；
4、可在大范围温度变化（5℃~40℃）条件下实现准确测量；
5、如有高温测量要求，可选择定制款，实现5~100℃控温条件下测量，温度控制精度±1℃；

1. A new type of dilatometer bench structure has been developed independently, which makes the test results more accurate than ASTM C1698. At present, the dilatometer bench structure has been patented
2.The size of corrugated plastic tubes can be customized according to the user requirements, and suitable dilatometer benches should be processed.
3.The numbers of test channel can be customized. There are 3 channels, 6 channels , 9 channels and 12 channels to choose, and more channels can be customized according to the user requirements.
4. Accurate measurement can be realized under the condition of wide range temperature change (5 ~40℃).
