Heat Flow Meter

Thermal conductivity measuring device with heat flow meter according to ISO 8301, ASTM C 518, DIN EN 1946-3, EN 12664, EN 12667 and EN 12939

Measuring devices of the HFM 518 series are compact, robust desktop devices equipped with an integrated Single Board Computer (SBC) with Windows 10 operating system, the software Lambda 2016 and a high resolution color touch display that can be operated in standalone mode.  

Numerous interfaces such as RS232, USB and Gigabit Ethernet enable the connectivity to peripheral devices and the fast and convenient transfer of all relevant data. The direct connection to a printer allows for printing test reports without using an additional PC.
