ZFY-4 waterproofing membrane electric impermeability tester

ZFY-4 waterproof membrane electric impermeability tester

Overview:

ZFY-4 electric waterproofing membrane impermeability tester is used for impermeability detection of petroleum asphalt linoleum and elastic full bitumen water-proof membrane. This instrument can meet the test requirements specified in GB / 328-2007 and GB18173-2006, JC-7974-2005, GB12952-2011 standards. This instrument uses an electric air pump for pressurization. This tester can be widely applied in the research, construction, production, design and teaching departments.

This product uses electrical automatic control for pressurization, automatic pressure maintenance, digital timer. It is a very handy device for impermeability detection of linoleum and waterproofing membrane, testing and research. In case of the test pressure is less than 0.6Mpa, this instrument can be used for measuring air permeability or water permeability of any other related materials.

Second, the technical parameters:

1, Power: 220V 50HZ
