Product Category: Density Measurement
True density is one of the important parameters in measuring physical property of solid materials, especially powder. Value of true density depends on material purity and compactness which affect the quality of sample. The traditional measuring true density of materials is based on Archimedes water displacement method. As the serious inaccuracy of manual operation and drainage exists, ISO (the International Standard Organization) officially implemented gas displacement method (ISO 12154) to test the true density in 2014. JWGB Densi 100 Series True Density Analyzer can quickly and accurately produce true volume and true density of various solid materials such as powders and blocks. The sample chamber volume range is 1 cm³ - 100 cm³. It takes about 3 minutes to complete analyses without influencing accuracy.
Self-developed Kernel Module
Setting sample chamber, expansion chamber, pressure sensor, control valve in one, ensuring homogeneity of test system temperature. Accuracy of true density test can be better than ± 0.03%, repeatability is better than ± 0.02%;
Densi 100 with 2 bar (F.S.) makes test has a good result in the true density measurements.
Non Linearity of pressure sensor is better than ± 0.2% which benefits recording pressure. .
Densi 100 Automatic True Density Analyzer can accurately measure true density of powder over 1-1.3 bar pressure ranges. Do not use vacuum pumps during testing to avoid pumping samples to pollute analyzer.

The Densi 100 provides automatic tests for user. It takes about 3 minutes to complete a test. Users can free to set up repeat times, test data is automatically saved and displayed in txt files, results can be exported through USB port. Densi 100 is configured with PC-side standard test report generate and print software.
Standard substance is made by non-expanded alloy and calibrated by National Institute Metrology, China. Volume precision is up to 10-4 cc.
