1、 Applicable scope
This energy-saving muffle furnace is a new generation intelligent product with high-performance electromechanical integration, suitable for industrial analysis in industries and departments such as coal, electricity, chemical, metallurgy, cement, geological exploration, medicine, scientific research, etc. This instrument uses a microprocessor as the control center and touch keyboard input. When conducting coal quality analysis, it is necessary to strictly follow the national standard GB212 According to relevant regulations of GB5447 and GB5449, automatic determination of slow ash, fast ash, bonding index, volatile matter, etc.
2、 Functional characteristics
By using a 4.3/7-inch color touch screen and intelligent control technology, the test progress, time, temperature, and function can be displayed simultaneously, which can reduce visual reading and human operation errors and greatly improve work efficiency. Support optional programs with multiple segmented settings;
Adopting various fault self inspection programs to provide comprehensive protection for the furnace hall;
Adopting PID control algorithm and adaptive control technology, the temperature control accuracy is better than the national standard requirements, and the performance is stable and reliable;
Temperature control complies with national standard GB212 According to GB5447 and GB5449, it has specialized heating programs such as fast ashing method, slow ashing, volatile matter, and bonding index, with superior performance and high control accuracy;
