DRM-2W Thermal Conductivity Tester

1. Overview:

The thermal conductivity of the material itself has the ability to conduct heat, and its thermal conductivity and insulation performance are usually measured by the thermal conductivity coefficient. The DRM-2W thermal conductivity meter is designed in accordance with the methods and relevant parameters determined in the "JGJ51-2002, J215-2002 Technical Specification for Lightweight Aggregate Concrete". It is based on the non steady state thermal pulse method heat flow principle, and short-term heating is applied to the test material to change the temperature in the test material. Based on its changing characteristics, the thermal conductivity coefficient, specific heat capacity, and heat storage coefficient of the test material can be calculated. This instrument is controlled by a microprocessor, with keyboard input, digital display, and automatic printing and output of results. It is easy to operate and has fast testing speed (about 20 minutes per test). It is an upgraded product of the DRM -1W flat thermal conductivity meter.
