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 ability of the materials used in the structure to resist the penetration of water or other liquid (light oil, heavy oil) media under pressure. SJS-1.5 anti-seepage tester is mainly used for the test of mortar anti-seepage performance and the determination of anti-seepage 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. The function of SJS-1.5S digital display anti-seepage instrument is the same as that of ordinary type. Its main feature is that the pressure value is displayed on the pressure display instrument 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.
