HFM L57
Brand: Linseis | Category: Nanotechnology
The HFM L57 is a heat flow meter that determines the thermal conductivity of insulating and low conductivity materials. The sample is held between two temperature-controlled plates and the heat flow through it is measured. Design follows ASTM C518, JIS A1412, ISO 8301, DIN EN 12664 and DIN 12667.

- TIM L58
The TIM L58 measures the thermal resistance of thermal interface materials under realistic contact pressure. Sample thickness and applied force are varied to reproduce assembly conditions, with evaluation routines to ASTM D5470. It is used in electronics, battery and thermal management work.
- THB L56
The THB L56 is a transient hot bridge instrument for thermal conductivity, thermal diffusivity and specific heat capacity. It measures absolute values on solids, liquids, pastes and powders with a sensor placed against the sample. Three model levels, Basic, Advanced and Ultimate, are offered.
- LZT L32
The LZT L32, also published as the LZT-Meter, combines an LSR and an LFA in one instrument, so thermal conductivity, electrical resistance and the Seebeck coefficient are measured on the same sample. These values give the thermoelectric figure of merit ZT. Interchangeable furnaces cover -100 C to 1100 C.
