Product Description: The electrothermal high-temperature blast drying oven is widely used in electrical and mechanical, chemical, plastic, light industry and other industries and scientific research units for baking, drying, curing, heat treatment and other heating of various products and samples. Features: 1. Mirror surface stainless steel liner is adopted, the four corners are semi-circular arc transition, and the shelf bracket can be freely installed and unloaded, which is convenient for cleaning in the box. 2. Using the latest P.I.D fuzzy logic processing controller, the set value can be reached quickly and the operation is more accurate and stable. 3. There is a 25mm diameter test hole on the left side of the box, which is convenient for experiment operation and temperature measurement. 4. Independent temperature limit alarm system, automatically interrupts when the temperature exceeds the limit, to ensure the safe operation of the experiment without accidents. (Optional) 5. Multi-segment programmable control, each segment can be preset for 1 to 99 hours and 99 minutes, which can simplify the complex experimental process and truly realize automatic control and operation. (Optional) 6. It can be equipped with a printer or RS485 interface, used to connect to a printer or a computer, and can record changes in temperature parameters. (Optional) Technical Parameter:
