DRH-III Double Plate Thermal Conductivity Measuring Instrument Protective Hot Plate Meter
Product Description
The DRH-III double plate thermal conductivity tester operates on the principle of unidirectional stable thermal conductivity. It measures heat flow through the sample's effective heat transfer area along with temperature differences and thickness to calculate thermal conductivity with high precision. Features include automatic data acquisition, processing, report printing, and storage with short measurement time, accurate data, excellent repeatability, and high automation.
Purpose
This instrument tests thermal conductivity for various materials including plastics, rubber, glass, fibers, insulation boards, foams, concrete, wood, and more. It also accommodates granular, bulk, and soft materials.
