The JL-1206B True Density Tester is designed in accordance with relevant national standards and is equipped with computer-based operating software, enabling rapid measurement of the true density of powders and bulk solids, as well as the porosity of porous materials. The instrument employs self-developed specialized software to control the entire testing process. After placing the sample into the test chamber, simply click "Test" to complete the process automatically. A single sample test takes approximately 3 minutes, supports repeated testing and automatic data saving, and allows for exporting reports in multiple formats such as PDF and TXT. True density refers to the actual density of solid materials after removing internal pores and is a fundamental physical parameter of powder materials. Based on the gas volume displacement method, this instrument effectively reduces errors caused by manual operations and sample dissolution compared to traditional pycnometer methods.
1. The instrument integrates a sample testing chamber, measuring cylinder, pressure sensor, and control valve into one unit, ensuring temperature stability of the system, with a testing accuracy of up to ±0.01% and a resolution of 0.00001 g/cm³. 2. It adopts a fully sealed integrated structure with a unique sample chamber filtration device, effectively preventing powder splashing during testing. 3. It features automatic calibration and gas path self-check functions, enabling automatic detection of system sealing and intelligent pressurization and depressurization control. 4. The relative working pressure can be adjusted within a range of 5% to 90%, reducing the impact on easily deformable samples. 5. Equipped with a standard vacuum pump, it is suitable for highly reactive or adsorptive powders or microporous materials at room temperature. Testing involves vacuum extraction followed by injection of a single gas (such as nitrogen or helium). 6. It includes a built-in fixed 100 ml testing chamber and allows flexible selection of 10 ml, 30 ml, or 60 ml sample measuring cylinders to accommodate different sample volumes and shapes. 7. The instrument employs an intelligent steady-flow system and a high-speed, high-resolution sampler, ensuring fast and accurate pressure curve measurement with high data resolution and repeatability. 8. It is equipped with a standard stainless steel ball for instrument calibration verification, ensuring testing accuracy.
This instrument operates on the principle of gas displacement volumetry. The International Organization for Standardization (ISO) officially adopted this method in 2014 for analyzing the true density of powders, granules, and similar materials. By measuring the volume of displaced gas, the true density of the material can be calculated based on the known apparent volume of the sample. Additionally, it can simultaneously measure the closed porosity and total porosity of porous materials.
True density testing: powders, granules, bulk materials, flakes, slurries, etc.; Porosity (open porosity, closed porosity) testing: bulk materials, foamed materials, etc.

1. Place the sample into the test chamber following the operating procedure. 2. Click the test menu in the computer software, and the instrument will automatically start components such as the vacuum pump and solenoid valve to begin operation. 3. After the test is completed, the software automatically saves the data, and users can view it online or export reports in formats such as PDF and TXT.
• Ensure the sample is dry and meets testing requirements before testing. • Select the appropriate testing mode (such as vacuum mode) based on sample characteristics (e.g., activity, adsorption capacity, pore size). • Do not open the testing chamber during the process to avoid affecting test results or causing powder splatter. • Regularly calibrate the instrument using the provided standard stainless steel balls to ensure testing accuracy. • Pay attention to the adjustment range of working pressure to avoid applying excessive pressure to easily deformable samples. • Place the instrument in a stable environment to avoid vibrations and drastic temperature changes. • Follow the prompts in the software during operation to prevent errors.
