Specialized lifting resistance furnace for scientific research, temperature control range 1200-1700℃, resistant to rapid thermal cycling without cracking.

Purpose: Widely used in production and experiments in the fields of ceramics, metallurgy, electronics, glass, chemical industry, machinery, refractory materials, new material development, special materials, building materials, etc.

Features:Door opening method: Bottom opening
Control accuracy: ±1℃; Furnace temperature uniformity: ±1℃ (depending on the size of the heating chamber).
Easy to operate, programmable, PID self-tuning, automatic heating, automatic heat preservation, automatic cooling, no need for supervision; Can be additionally equipped with computer communication to operate the electric furnace through the computer (start the electric furnace, stop the electric furnace, pause heating, set heating curve, store heating curve, historical curve, etc.), software
Fast heating (heating rate adjustable from 1℃/h to 40℃/min).
Energy-saving (the furnace chamber is made of ceramic fiber, which is resistant to high temperature, rapid heating and rapid cooling)
The furnace body is finely sprayed to resist corrosion and acid and alkali. The furnace body is isolated from the furnace chamber and adopts air cooling, so the furnace wall temperature is close to room temperature.
Dual-loop protection (overtemperature, overpressure, overcurrent, thermocouple break, power failure, etc.)
The furnace chamber is made of refractory materials, with good thermal insulation performance, high temperature resistance, and resistance to rapid cooling and heating.
