1.High efficiency vacuum system provides a wide negative pressure range of -70kPa to 0kPa .
2.Specialized end caps are suitable for various of pipe samples.
3.Cantilever lifting structure is introduced to expand the testing space, making a wide range of manholes from Φ315mm to Φ1200mm.
4.Deformation sensors adjustable to different directions, are applicable to the conditions of uneven samples or reinforced sample surface.
5.Industrial control terminal and colorful touch screen display provide more information to operator, e.g. pressure-time and deformation-time curves, leakage detection. Once there is leakage or unstability on sample, vaccum pump will stop working automatically.
6.Test data can be exported through USB port.
7.Test data will be saved automatically in case of abnormal interruption. Test time will be continued after system up to setting pressure.
