Papua New Guinea Fully Automatic Low-Temperature Specific Heat Capacity Tester
Product Description
Xiangke BRR-DW Fully Automatic Low-Temperature Specific Heat Capacity Tester
I. Overview:
This instrument is designed and manufactured in accordance with the GJB 330A-2000 testing method for the specific heat capacity of solid materials at 60-273K (60-373K adiabatic method). All measurements and controls are computer-controlled, reducing human error and improving testing accuracy. Computer interface operation enables fully automatic control, data acquisition and processing, display, and print output of the instrument.
This instrument uses the adiabatic method to test the specific heat capacity of solid (powder, small pieces, or small blocks) metallic and non-metallic materials at low temperatures. It is widely used in production enterprises, quality inspection departments, universities, and research institutes.
