  • True density measurement device
    Patent number: 10190956
    Abstract: This true density measurement device is a device that is used to measure the true density of a sample by a gas phase substitution method, and is provided with: a sample chamber for accommodating the sample, the sample chamber being pressurized through the introduction of an inert gas; and an expansion chamber into which is released the inert gas filling the sample chamber. The expansion chamber under conditions of normal use, is opened and closed by a detachable cover, and the volume thereof is modified by insertion or withdrawal of a volume modification member.
    Type: Grant
