This DZ-3500S carbon black content tester is suitable for the determination of carbon black content in polyethylene, polypropylene, polybutene plastics, cable and optical cable insulation and sheath materials, and rubber. Comply with national standards ISO 6964, ASTM D1603, GBT 3515-2005, GBT 13021-1991, GB/T2951.41-2008, IEC60811-4-1:2004, etc. A certain amount of sample is pyrolyzed in a nitrogen flow at high temperature, and the carbon black content is obtained by analyzing the weight of the sample after pyrolysis.

Technical Features:
1. The appearance and structure of the instrument are beautiful, and the operation is simple;
2. The integrated design of the heating furnace body and the control system is convenient for the user’s instrument management;
3. High degree of automation, only need to set the temperature value and heating time, the instrument will automatically heat up to the set value;
4. High temperature control accuracy, wide temperature range and high furnace temperature uniformity;
5.8-inch LCD touch screen display, extremely friendly operation interface, can be started with one key operation;
6. It has a constant temperature function, and the constant temperature time can be set, and the constant temperature precision is high;
7. The instrument can set any group of different heating time periods, and can have different heating temperature, heating rate, and constant temperature time;
8. Parameter display is comprehensive, showing the number of set groups, theoretical temperature, actual temperature, heating time (or constant temperature time);
9. During the operation of the instrument, you can view the set parameters and the time for heating or constant temperature.
