For some buildings, such as hydraulic construction, underwater, underwater, underground and other construction projects, buildings are required to have special properties - impermeability. The so-called impermeability refers to the performance of the materials used in the structure to resist the penetration of water or other liquid (light oil, heavy oil) media under pressure. HS-4 type impermeability tester is mainly used for the test of concrete impermeability performance and the determination of impermeability grade. At the same time, it can also be used to measure the air permeability of building materials and check the quality. Therefore, it has been widely used in production, construction, design, teaching and research departments. HS-4S type anti-seepage meter: the function is the same as that of the ordinary type, its main feature is that the pressure value is displayed on the pressure display through the sensor, and it can automatically increase the pressure and complete the test according to the set program, reducing the burden on the staff. Both HS-4 and HS-4S impermeability testers meet the requirements of GB/T50082 "Standards for Test Methods of Long-term Performance and Durability of Ordinary Concrete" and other standards.
