4、 Performance characteristics:

In addition to the testing programs for industrial analysis such as slow ash, fast ash, volatilization, and bonding that traditional control instruments have, a powerful custom setting program (referred to as "self selection") has been added. The self selection setting program can set 50 independent programs, and each independent program can set different constant temperature points and constant temperature times. Powerful functionality, good compatibility, and can meet the needs of multiple industries.

During the volatile matter experiment, the effect of restoring 900 ± 10 ℃ within 3 minutes was excellent. The authenticity of the restored temperature and the accuracy of the experimental results data are the biggest features of the temperature control effect of this product.

This intelligent furnace adopts PID algorithm and fuzzy control technology, automatically corrects the measured temperature, automatically shifts the phase to trigger the thyristor conduction angle, and controls the heating power.
