L75 / HP High Pressure Dilatometer

L75 / HP High Pressure Dilatometer


The Linseis high-pressure dilatometer L75/HP enables completely new applications in thermal analysis. The system can measure expansions (length changes) in the temperature range from RT up to 1100/1400/1800°C and in the pressure range up to 100/150 bar. This device is the world’s only available high-pressure dilatometer. A steam generator and camplex gas control system are optional available.

An get even more informations and extend your measeurement, an analysis of the effluent gases can be done by using a QMS or FTIR system at any time. But the coupling is more than only the sum of the separate parts. You can benefit from LINSEIS coupling knowledge and integrated hard- and software concept. For the interpretation of the results, different libraries are available.
