PMIC Testing Instruments

Model: TKE-1225

Test Type: Thermal Conductivity, Guarded Comparative Heat Flow Meter, ASTM E1225
PMIC’s Guarded-Comparative-Longitudinal Heat Flow System is ideal for evaluating materials in the moderate to high conductivity range. It is based on ASTM E1225 and provides a Windows based real time thermal conductivity versus temperature recording and interface for ease of use with maximum resolution and accuracy.

The TKE-1225 is custom designed to allow for a wide range of specimen size and shape and to provide sampling over a temperature range from -228°C (45K) to 650°C (923K). It is designed for ease of use, safe operation, efficiency, and has a compact design for a system that offers such varied parameters.
