Product Details

JL-1206BFully automatic true density/porosity tester

according toNational GB/T 24586-2009 standard for determination of true density and porosity,Equipped with computer operating software,Can quickly measure the true density of various powders, block solids, and the porosity of porous materials.Independently developed specialized testing software, computer-controlled throughout the testing process. Samples are placed into the testing chamber according to the operating procedures, and when the testing menu is clicked, the vacuum pump, solenoid valve, and other components immediately respond and start working simultaneously. Testing one sample takes about 3 minutes to complete, and can be repeated multiple times. The software automatically saves test data and supports online viewing and exporting of diverse report forms such as PDF, Excel, TXT, etc.

True density refers to the actual mass of solid material per unit volume in a dense state, that is, the density after removing internal pores or gaps between particles. True density is the most basic physical parameter of powder materials. After knowing the apparent volume of the sample, the closed pores and porosity of the porous material can be tested simultaneously. The traditional method for measuring true density is based on the Archimedes principle using a specific gravity bottle. This method is prone to reading errors and testing errors caused by sample dissolution when manually operatedThe ISO standard organization officially implemented the gas volume displacement method for analyzing the true density of powders, particles, etc. in 2014.

Application field

vTrue density testing: powder, particle, block, sheet, slurry, etc

vPorosity (open porosity, closed porosity) testing: block materials, foam materials, etc

JL-1206BFully automatic true density/porosity testerTest Principle

Testing method for true densityIt is to add the sample into a container with a known volume, seal the container and introduce a certain amount of nitrogen gas. The pressure sensor measures the internal pressure of the container, and then the gas inside the container diffuses to another container with a known pressure and volume. The pressure sensor measures the equilibrium pressure inside two connected containers, and the computer controls the fully automatic testing and analysis. According to the gas law, the true volume of the sample is obtained, and the true density is calculated by dividing the sample mass by the volume.

For sample analysis and testing purposes.

vThe relative working pressure can be adjusted within the range of 5% -90% to reduce the impact of working pressure on easily deformed samples.

vPowder materials with strong activity and adsorption at room temperature or porous materials with small pores are suitable for vacuum type testing, because vacuum type testing first requires the extraction of all adsorbed gases inside the sample, and then the injection of nitrogen or helium gas, which is always a single gas during the testing process.

vThe intelligent steady flow system and high-speed, high-resolution sampler can quickly and accurately measure pressure curves, ensuring the resolution and repeatability of test data.
