The mass density is defined as the ratio between mass and volume.
density, are suitable for a wide range of applications. The design of the device permits samples to be inserted into the test chamber from any side. This allows for the insertion of heavy and complex samples without damaging the measuring plates. Data acquisition and control of the device are handled by the external Lambda Control desktop device alongside a PC with Windows operating system and Lambda software.
NETZSCH TAURUS Instruments GmbH primarily focuses on devices for measuring the thermal conductivity of building, construction and insulating materials.

Guarded Hot Plate - Principle of Operation
The hot plate and the guard ring are sandwiched between two samples of the same material and approximately the same thickness, d. Cold plates are placed above and below the samples. All plate temperatures are controlled such that a well‐ defined, user‐selectable temperature difference, ΔT, is established between the hot and the cold plates – and thus across the sample thickness. The guard ring is maintained exactly at hot plate temperature in order to minimize lateral heat losses.
