May 2026
Fredericton, NB – The Zentrum fuer Waermemanagement (hereinafter referred to as “ZFW”) has launched worldwide sales of a new High Temperature Heat Flow Meter to test thermal and mechanical properties of insulation materials at temperatures up to 850 °C.
C-Therm Technologies is the exclusive distributor of ZFW’s TIM-Tester in North America and is excited to support the distribution of the new Guarded Heat Flow Meter (GHFM). The instrument is capable of measuring thermal conductivity, thermal resistance, force, and compression with high accuracy and reproducibility.
ZFW’s High Temperature Heat Flow Meter is engineered to deliver precise and reliable material characterization across an expanded temperature range. Designed for use in demanding research environments, it is ideal for applications in aerospace, defence, battery cells pads, thermal barrier materials, thermal runaway protection systems, and high performance insulation development.
