Xiangtan XiangkeBRR-3AFully Automatic High-Temperature Specific Heat Capacity Tester
I. Overview:
The instrumentPlease provide the Chinese content you would like translated into American English.Refer toGJB 330A-2000Solid Materials60-2773KCalorimetric Test Method) Design and Manufacturing. Utilizes the copper card mixing method (shortened to the mixing method) to test the specific heat capacity of solid materials (including powdery and fibrous materials with difficult shaping) at high temperatures. Widely used in manufacturing enterprises, quality inspection departments, universities, research institutions, and other scientific research units.
The instrument employs computer control for all measurements and controls, minimizing human error and enhancing test accuracy. Full automation of the instrument, data collection and processing, display, and print output are achieved through the use of a computer interface.

III. Working Principle:
Hang the sample of known quality in a heating electric furnace for heating, when the temperature of the sample reaches the set temperatureT1Once stabilized, place it in an automatically insulated environment with an initial temperature ofTcThe sample is placed in a copper block calorimeter, where it releases heat, causing the calorimeter's temperature to rise to the final temperature.TnBy measuring the temperature rise of the calorimeter, the average specific heat capacity of the sample can be determined.
Instrumentation Configuration: IncludesBRR-3AOne high-temperature specific heat capacity tester unit, one software set, one communication interface and data cable set, one high-precision constant temperature water bath unit, one brand desktop computer (configured according to the contract).
