Densi100 Automatic True Density Analyzer
Product Category: Density Measurement
Industry: Analytical and Environmental Labs, Batteries, General Laboratory, Mining and materials, Particle and surface science
Supplier: AMI
Description
Gas replacement (also known as gas gravity bottle) is one of the most reliable methods for measuring apparent volume and density. This method uses a gas to measure the volume of a sample. The gas used is ammonia, which does not cause damage to the sample. The gas displacement method is more accurate and reproducible than the traditional Acimede immersion method. In 2014, the International ISO Standards Organization officially introduced the gas volume replacement method for testing true density.
Densi-100 is a fully automatic gas displacement true density tester, which can quickly and accurately measure the volume and automatically calculate the density of various powders, blocks and other materials.
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 up to ± 0.03%, repeatability is less than ± 0.02%;
Pressure Sensor
Densi 100A 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.
Standard Substances
Standard substance is made by non-expanded alloy and calibrated by National Institute Metrology, China. Volume precision is up to 10-4 cc.
Density Measurement
Densi 100A 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.
Unique Design
Controlling and operating by ARM &Windows CE without configuring computer for Densi 100A.The instrument is equipped with intelligent self-test program, which can automatically judge sealing of the test system and eliminate personal error.
| Sample test chamber | Sample cell | Conversion chamber |
|---|---|---|
| 10mL | 10mL | 1mL/3.5mL |
| 100mL | 100mL | 10mL/35mL |
Operating Software
Densi 100A 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 100A is configured with PC-side standard test report generate and print software.
