Product Description
A digital hot air oven is a lab and industrial device that sterilizes equipment and dries samples using dry heat. It uses a microprocessor-based controller with a digital display for precise temperature regulation (typically 50C to 250C) and forced-air circulation for uniform heating.
Key Features and Specifications
- Construction: Typically features a corrosion-resistant, polished stainless-steel inner chamber with adjustable shelves, and a powder-coated mild steel exterior.
- Temperature Controller: Equipped with an auto-tune PID (Proportional-Integral-Derivative) digital controller. It features a dual LED screen to simultaneously display the Process Value (PV) and Set Value (SV) with an accuracy of 1C to 2C.
- Air Circulation: Uses internal motorized fans/blowers to force hot air convection, which ensures consistent heat distribution and eliminates cold spots throughout the chamber.
- Insulation: The gap between the inner and outer walls is tightly packed with high-density materials like glass wool or PUF to minimize heat loss and maximize energy efficiency.
- Safety Mechanisms: Many digital models include built-in safety features such as over-temperature limiters (cut-offs), alarm indicators, and insulated handles to prevent burns.
- Timer Function: Integrated digital timers (often 0 to 999 minutes) allow for automated, repeatable sterilization and drying cycles.
