True density is a critical physical property for solid materials—especially powders—affecting everything from product performance to quality control. True density reflects a material’s purity and structural compactness, both of which play a direct role in its end-use properties.
Traditionally, density has been measured using Archimedes’ water displacement method. However, this approach suffers from manual error, liquid drainage issues, and poor repeatability. In response, the International Organization for Standardization (ISO) adopted the gas displacement method (ISO 12154) as the official standard for true density measurement in 2014.
The Densi 100 True Density Analyzer quickly and accurately determines the true volume and true density of a wide range of solid materials, including powders, granules, and solid blocks. With a sample chamber volume range of 1 cm³ to 100 cm³, the system accommodates both small and large samples. Each analysis is completed in approximately 3 minutes, delivering reliable results without compromising accuracy.

Features
Integrated Testing Module
The Densi 100 combines the sample chamber, expansion chamber, pressure sensor, and control valve into a single compact unit, ensuring uniform system temperature and enhanced measurement stability. This integrated design delivers true density accuracy of up to ±0.03% and repeatability better than ±0.02%.
Reference Material
The standard reference material is made from non-expanded alloy and certified by the National Institute of Metrology, China, ensuring traceability and high confidence in measurement accuracy with volume precision up to 10⁻⁴ cc.
Multiple Sample Chambers and Inserts
Various chamber and sample cell inserts are available, allowing users to optimize measurement accuracy and accommodate different sample volumes with precision and flexibility.
Density Measurement
The Densi 100 accurately measures true density of powders within a pressure range of 1 to 1.3 bar.
Unique Design
Equipped with a built-in processor and Windows-based operating system, the Densi 100 operates independently without requiring an external computer. Its intelligent self-diagnostic system verifies seal integrity automatically, reducing operator error and ensuring consistent, high-quality results.
Pressure Sensor
The Densi 100 uses a 2 bar (F.S.) pressure sensor with nonlinearity better than ±0.2%, delivering stable, precise pressure readings and reliable data capture throughout testing.
