Heat Flow Meter HFM Series: HFM-100 HT/HFM-100/HFM-50
The Heat Flow Meter is an easy-to-use technique for steady-state measuring the thermal resistance and thermal conductivity of homogeneous and heterogeneous samples like insulation products, construction materials, packaging, and assemblies. Our HFM series was designed and engineered to combine the highest accuracy, repeatability, widest temperature range, and industry leading performance all at an exceptional value.
The second-generation HFM Series meets rigorous international standards such as ASTM C518, ASTM C1784, ISO 8301, JIS A1412, EN 12667 and EN 12664
