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.
