LRR-3A Automatic High Temperature Heat Capacity Measurement Instrument
LRR-3A Automatic High-Temperature Heat Capacity Measurement Instrument
1.Description:
This instrument is designed and manufactured in accordance with GJB 330A-2000 (Test Method for Specific Heat Capacity of Solid Materials - 60-2773K). It uses the copper card method combined with the mixing method (referred to as the mixing method) to test the specific heat capacity of solid materials (including powdery, fiLRous and other difficult-to-form materials) at high temperatures. It is widely used in manufacturing enterprises, quality inspection departments, universities and research institutes and other scientific research units.
All the measurements and controls of this instrument are carried out through computer control, which reduces human errors and improves the test accuracy. The instrument is fully automated through computer interface operation, including data acquisition and processing, display and printing output
