# Thermal Diffusivity & Thermal Conductivity > LZT-Meter

The Linseis LZT Meter is the worlds first commercially available instrument that allows the determination of the thermoelectric Figure of Merrit ZT by means of a combined LaserFlash (LFA 1000) and LSR measurement in a single instrument.

Accordingly, an independent determination of the thermal conductivity by means of a flash method as well as a measurement of the electrical resistance and of the Seebeck-Coefficient (known from the LSR platform) can be carried out with this measuring device.
