Characteristics of intelligent muffle furnace:
1. Heat from both sides and the top three sides of the furnace to ensure uniform temperature distribution.
2. The double-layer furnace shell structure is stable; The furnace shell is made of high-quality cold plate and stainless steel plate materials with electrostatic spraying.
3. The use of high-quality vacuum fiber furnace has good insulation effect, fast heating speed, and significant energy-saving points. Compared with traditional muffle furnaces, it saves 1/2 of time and 2/3 of electricity.
4. Adopting a brand new Chinese display and user-friendly human-machine interface. Intelligent control technology, simultaneous display of test progress, time, temperature, and function, can reduce visual reading and human operation errors, greatly improving work efficiency.
5. Using a microprocessor as the control center, the intelligent judgment method of the microprocessor is used to automatically adjust the preheating temperature and store the memory to ensure the smooth completion of the experiment with a high degree of automation.
6. The temperature control complies with the national standards GB212, GB5447, and GB5449, and has specialized heating programs such as rapid ashing, slow ashing, volatile matter, Roga index, and bonding index, with superior performance and high control accuracy.
7. It has a self selected program, and users can set fifteen time temperature control processes according to their needs to complete various temperature rise curve controls. It is widely used and easy to operate.
8. The overall design is reasonable, the appearance is beautiful, the craftsmanship is exquisite, it is sturdy and durable, and the service life is long. It adopts a dual rotation center, a four arm horizontal rotating furnace door, and a new controllable chimney switch device, which is easy to operate.
