Impermeability of concrete instrument Concrete is an artificial stone of the building now widely used for some buildings, such as: hydraulic construction, underwater water, underground and other construction projects requiring concrete structures with special properties, the impermeability of the performance of the so-called impermeability refers to the performance of coagulation to resist penetration by water or other liquid media under pressure. Automatically adjust the impermeability of concrete instrument microcomputer control, replacing the electrical contacts and electrical control part, without every eight hours of artificial Surge, high control precision, fast response, reliable technical performance, rational design of circuits and panel easy to operate Shanghai Rong amounted Experimental Instrument Co., Ltd. Manufacturing Technical parameters of concrete permeability instrument A maximum working pressure: 4mpa 2: Automatic constant voltage （digital display: automatic constant voltage and automatically boost） 3, one can be used for specimen number: 6 4, the geometric dimensions of the test mode （also known as the main mode） Cavity to catchy diameter: φ174.8mm Cavity mouth diameter: φ5mm Height: 153mm 5 plunger pump parameters: flow rate: 0.16L/min 6, voltage: 380V-50HZ Power: 120W Dimensions: 950 × 800 × 950mm 8 Quality: ≈ 220kg
