DHG-9425 Large-Capacity 420L Mechanical Convection Dry Oven with Digital Temperature Controller
The DHG-9425 oven is engineered to meet demanding laboratory drying, material storage, wax melting, and heat sterilization needs where uniform and reliable heating is critical. Its large 420-liter stainless steel chamber accommodates bulky samples or multiple batches simultaneously, supporting efficient workflows in research and industrial labs. The oven’s mechanical convection system circulates heated air evenly throughout the chamber, ensuring consistent temperature distribution and reproducible results across all shelf positions.
Equipped with a digital temperature controller, the DHG-9425 maintains temperature stability within ±1°C and uniformity within ±2°C at 100°C, enabling precise thermal processing up to a maximum continuous operating temperature of 250°C. Safety is enhanced by an independent over-temperature protection sensor that automatically cuts power if overheating occurs. The chamber includes three stainless steel shelves, each capable of supporting approximately 10 kg, allowing flexible sample arrangement without compromising airflow.
