Outline

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.

Datasheet

Features

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%;

Pressure Sensor
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. .

Density Measurement
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.
