Measuring instrument for heat transfer through material contact

2024-05-31 14:21

  Product Introduction

  The material contact heat transfer tester is designed, developed, and manufactured according to ISO12127-2007 and EN702. The instrument measures the heat transfer performance of the sample at a certain temperature by contacting it with a heating cylinder and a calorimeter under a certain load. This instrument has simple operation, accurate data, and is safe and reliable.

  Reference standards

  ISO12127-2007 Flame retardant and fire-resistant protective clothing - Determination of thermal conductivity through contact with protective clothing or its constituent materials

  EN702 Protective clothing - Heat and fire resistance - Test methods - Contact heat conduction test through protective clothing or its materials

  Product application

  The material contact heat transfer tester is suitable for measuring the heat transfer performance of specimens, such as measuring the thermal conductivity of contact heat through protective clothing or its constituent materials. It is widely used in companies and testing departments related to fire protection clothing.
