KDRX-II transient fast hot wire method thermal conductivity tester

Detailed introduction

KDRX-II transient fast hot wire method thermal conductivity tester

I. Overview:

The hot wire method for thermal conductivity (transient method) is measured using a line source test method of a thermal probe. This thermal probe has a very large aspect ratio to achieve infinite and thin heat source simulation conditions. Simple to use, plug-and-play probe sensor quick interface method and simple software interface operation make the user quickly grasp and operate accurately. It usually takes only 1-2 minutes from the start of preparing the test to obtaining the results. It has the advantages of wide application range, fast measurement speed, accurate measurement results, etc. It has the advantages of small size, convenient carrying, and higher cost performance to meet the requirements of production, quality inspection and research and development in related industries.

   The instrument complies with: Standard ASTM D5334-2008 "Standard Test Method for Determining Thermal Conductivity of Soil and Soft Rock by Hot Needle Probe Method"; GB / T 10297-2015 "Hotline Method for Determining Thermal Conductivity of Non- Metal Solid Materials"; GB / T 11205-2009 " Hot wire method for the determination of thermal conductivity of rubber "; ASTM C1113-2009 " Test method for measuring the thermal conductivity of refractory products using hot wire "; ASTM D5930-2009 " Standard test method for measuring the thermal conductivity of plastics using instantaneous linear source technology ".
