GHP 500 – Thermal Conductivity Tester

Guarded Hot Plate with touch display – especially for thick specimens!

Measuring devices of the GHP 500 series are robust cabinet devices which are especially suited for testing thicker specimens. Thanks to the integrated single board computer (SBC) with Windows operating system, the Lambda software and the high-resolution color touch display, the devices are very user-friendly.
Numerous interfaces such as RS232, USB and Gigabit Ethernet enable connectivity to peripheral devices and allow for fast and convenient data transfer.
Connection to an external PC allows for the extensive evaluation of test results and the printing of test reports.
