Detailed Parameters Of The Product
Product Overview:
    The touch screen three-temperature zone tube furnace is a CE-certified three-temperature zone open tube furnace. Each temperature zone is controlled by three independent temperature control systems, and the temperature of each temperature zone is adjusted. , Can form four-stage temperature gradient in the heating zone or form a longer constant temperature zone. Each temperature control system is adjusted in PID mode, and 30 steps of temperature rise and fall programs can be set. The K-type thermocouple is used for temperature measurement and control, and its temperature control accuracy can reach +/- 1℃.
