HY4660 Carbon Black Content Tester is used to determine the carbon black content of polyolefin compositions. The principle is: pyrolysis of a specified quantity of mixture at a specified temperature in a stream of nitrogen for a certain time and calcination at a specified temperature; Calculation of the carbon black content from the difference in mass before and after calcination and pyrolysis. This instrument complies with the following international and industry standards. ISO: ISO 6964. ASTM: ASTM D1603. GB/T: GB/T 2951.41. Beautiful appearance, LCD display, easy to operate. Openable furnace door, easy to place specimen. High accuracy of temperature, large temperature range, excellent temperature uniformity in the chamber. Can set keeping time for constant temperature, high accuracy of keeping constant temperature. Can set 30 groups of temperature programs, can set heating temperature, heating speed, keeping time for constant temperature for each program.
