Description

KDRX-II transient hot wire method thermal conductivity tester ASTM C1113 ASTM D5344 Refractory Thermal conductivity tester

1.Product introduction

The hot-wire thermal conductivity meter (transient method) is measured using the line source test method of the thermal probe, which has a very large aspect ratio to achieve the simulation conditions of an infinitely long, infinitely thin heat source. Simple to use, plug and play probe sensor fast interface mode and simple software interface operation, so that users can quickly grasp and accurately operate. From the time you start preparing the test to the time you get the results, it usually only takes one to two minutes. Wide application range, fast measurement speed, accurate measurement results and other advantages, with small size, easy to carry, higher cost performance to meet the needs of production, quality inspection, research and development of related industries.

The instrument conforms to the standard ASTM D5344-2008 “Standard test method for the Determination of Thermal Conductivity of Soil and soft stone by Hot Needle Probe Method”; GB/T 10297-2015 “non-metallic solid materials thermal conductivity determination hot-wire method”; GB/T 11205-2009 “Rubber thermal conductivity determination hot-wire method”; ASTM C1113-2009 “Test method for the Determination of Thermal Conductivity of Refractory Products by Hot Wire”; ASTM D5930-2009 “Standard test method for Measuring Heat Conductivity of Plastics by Instantaneous Linear Source Technique”.
