| Name | Function Introduction | Options | Function Code |
| Temperature Controller | Standard 50-segment heating curve; imported instruments can be selected alternatively (B) | Two choices | AB |
| Touchscreen | Chinese menu, storage of multiple heating process curves, storage of historical curves and data reports (7-inch) | Four choices | C |
| IoT Interface | The RS485 communication interface of the electric furnace reads and writes real-time data such as furnace start, pause, stop, heating curve, allowable time, etc. | D | |
| Computer Control Software and Hardware | The furnace can be controlled via computer for starting, pausing, stopping, setting heating curves, reading heating curves, and parameter adjustment with high reliability and easy operation. It displays measured value, set value, output value, segment time, segment number, heating curve, and power percentage curve. Heating curves can be stored, set values and common parameters modified via computer. Historical curves and reports can be saved for a long time with selectable time intervals (1s-1h). | E | |
| PLC | Adopts Siemens PLC control (capable of reading and writing furnace start, pause, stop, heating curve, time, temperature curve, atmosphere, flow, switch quantity, power supply, power); opens ports for serial and parallel data with upstream and downstream equipment | F | |
| Air Inlet | Float flowmeter + manual valve; the number of flowmeters, maximum output, and gas medium can be selected | Two choices | K |
| Digital display mass flowmeter; the number of flowmeters, maximum output, and gas medium can be selected | M | ||
| Air Outlet | Exhaust port, manually opened; DN30 | Two choices | T |
| Electrically opened, automatically opened or closed at segment N according to the heating curve | P | ||
| Fully Automatic Air Inlet and Outlet | Electric exhaust port and electric air inlet can be associated with heating curve segments to be automatically opened and closed at any temperature segment; PLC is used to realize automatic opening and closing during heating (on the premise of selecting the touchscreen function) | Y | |
| Vacuum Atmosphere | The feeding chamber, high-temperature furnace chamber as a whole, and discharging chamber adopt vacuum-sealed shells to prevent oxidation, and can be used with atmosphere | R | |
| High-Temperature Stirrer | Uses frequency converter and reducer for speed regulation; the stirrer rod is made of high-temperature ceramic | Z | |
| Independent Control Cabinet | Control system is separated from the furnace body; an independent control cabinet (1600x600x400) is added, and the length of the control cable is extended (within 5 meters) | Q | |
