DRPL-400 * 600 thermal conductivity tester (protective plate heat flux meter method)

1、 Overview

This instrument uses internationally popular heat flow meters to detect thermal conductivity and thermal resistance, and is equipped with a computer to achieve fully automatic detection and generate experimental reports. Based on the DRPL-I flat plate heat flux meter thermal conductivity tester produced by our company, it has been redesigned to meet the testing requirements of large-sized insulation materials.

This instrument is based on the principle of steady-state flat plate testing. A stable hot surface temperature is added to the hot surface, and heat is transferred to the cold surface through the sample. The heat flow transmitted is measured, and the thermal conductivity and thermal resistance can be calculated based on the thickness and heat transfer area of the sample. This testing method is simple, fast, and has good repeatability. It can be used for testing rock and soil, foam, cement, thermal insulation materials, etc., and is widely used in colleges and universities, scientific research institutes, quality inspection, factories and mines.

Reference standard of this instrument: ASTM C518-04 Test method for measuring steady-state Heat flux and heat transfer characteristics by heat flow meter method; GB10295-2008 Determination of steady-state thermal resistance and related characteristics of insulation materials (heat flux meter method).
