ZSY-4 (DTS-96) detected waterproofing membrane impermeable asphalt and petroleum bitumen membrane elasticity full impermeability of the instrument to meet the test requirements specified in GB / 328-2007. And suitable GB18173-2006, JC-7974-2005, GB12952-2011 standard. This instrument uses an electric pump pressure available to the research, construction, production, design and teaching departments. Using electrical automatic control filling pressure automatically maintain pressure, digital timer, for linoleum and waterproofing membrane impermeability of inspection, testing and research provides a very handy device. In the case of the test pressure is less than 0.6Mpa, you can use this instrument for the measurement of other relevant material permeability or permeable. Technical parameters: 1, Power: 220V 50HZ 2, test pressure: 0-0.6Mpa 3, you can try Qty: 3 (a group of) 4, specimen size: 150mm × 150mm 5, permeable plate inner diameter: Φ92mm 6, to test the water : 20 ℃ ± 5
