GHP 900 – Thermal Conductivity Tester

Tailored to research & development with customized heating plates!

Measuring devices of the GHP 900 series, which are especially designed for thicker specimens with a high gross 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.
