The DA-300PF sponge density and water absorption tester is currently in useIt is widely used in the market, mainly combining Archimedes' principle buoyancy method with modern microelectronics technology to achieve fast measurement of digital direct reading. Of course, it is not just about testing density values, but also extending various data through density, such as water absorption, porosity, volume change rate, content, volume, and so on. Please refer to the attached document for details.
