XiangkeDRPL-3BThermal Conductivity Tester (Heat Flow Meter Method)

Section 1:Overview

 This instrument employs the internationally popular thermal flowmeter method for measuring thermal conductivity, paired with a computer to achieve fully automatic detection. It is a product originally developed by our company.DRPL-2Optimized design based on the original.Enhanced with automatic pressure and thickness measurement functions, capable of conducting tests under various pressure conditions, and reducing manual measurement errors.Suitable for various common materials with different thermal conductivity coefficientsWith thermal resistanceTesting requirements.

This instrument operates based on the steady-state plate method testing principle, adding a stable surface temperature on the hot side, where heat is transferred through the sample to the cold side. The heat flux is measured, and the thermal conductivity and thermal resistance can be calculated based on the sample's thickness and heat transfer area. This testing method is simple, quick, and has good repeatability. It is highly suitable for research and development in material heat transfer. It can be used for nylon, plastic,SiliconRubber, graphite, thermal insulation materials, etc., are widely used for testing in colleges and universities, research institutions, quality inspection, and industrial and mining enterprises.

This instrument refers to the following standard:ASTM C518-04A testing method for determining steady-state heat flux and heat transfer characteristics using a thermal flowmeter.GB10295-2008Determination of Steady-State Thermal Resistance and Related Properties of Insulating Materials (Heat Flow Meter Method)、GB/T25261-2018Reflective Insulating Coatings for Architectural Use AppendixAThermal Conductivity Measurement。
