RJD-ST Concrete Surface Permeability Tester Introduction: The RJD-ST concrete surface permeability tester is used for non-destructive testing of air and water permeability, as well as water absorption on the surface of concrete or other building materials (including surface repair materials). This instrument is an excellent tool for evaluating the surface durability of materials exposed to ordinary or easily corrosive environments. It can be used in the office, on-site, and laboratory. This instrument is capable of simultaneously testing three key indicators (air permeability, water permeability, and material water absorption), allowing for complete and specific testing of structures. It is convenient to use, has a wide testing range, and can record and transmit data to a computer for data analysis. characteristic: 1. Testing permeability facilitates the development of repair or maintenance time plans, thereby reducing repair and recycling costs 2. The instrument can record and store a large amount of test data, and can be transmitted to a computer for data analysis 3. It can be tested on vertical, inclined, and horizontal surfaces 4. Belonging to non-destructive testing, the instrument is easy to use and portable, suitable for on-site use 5. Especially suitable for evaluating the protective performance of surface coatings, covering films, and repair layers Technical parameters: Pressure sensor: Range 1 bar Ultimate load: twice the standard range Pressure sensor accuracy: ± 1% range Operating temperature: 0~~50 ℃ Heat up time: 30s Test range: Air permeability coefficient 0-3.912Ln/min Absolute high permeability rate: 1L/min Sensitivity of test water flow: 1 μ L Overall parameters: Water storage capacity of 100ml/ External supply voltage: 10-15 VDC
