LRR-DW Low Temperature Automatic Calorimeter Thermal Analyzer
LRR-DW Automatic Low-Temperature Calorimeter Thermal Analyzer
1.Description:
This instrument is designed and manufactured in accordance with GJB 330A-2000 Solid Materials 60-273K Specific Heat Capacity Test Method (60-373K Isolated Method). All measurements and controls are carried out using computer control, reducing human errors and improving test accuracy. The instrument is fully automated through computer interface operation, including control, data acquisition and processing, display, and printing output.
This instrument uses the isolated method to test the specific heat capacity of solid (powdered, small pieces or small blocks) metallic and non-metallic materials at low temperatures. It is widely used in manufacturing enterprises, quality inspection departments, universities and research institutes and other scientific research units
