DHG9140A 136L Digital Convection Drying Oven with Stainless Steel Chamber, 10-250°C Temperature Range
DHG9140A is designed for laboratory drying, sterilization, and material storage tasks requiring precise and uniform heating. Its 136-liter stainless steel chamber accommodates moderate sample volumes, making it suitable for research and development environments where controlled temperature conditions are critical. The oven supports continuous operation from 10°C up to 250°C, enabling versatile processing of heat-sensitive materials.
The oven achieves uniform temperature distribution through convection heating, which circulates hot air evenly around samples. Temperature is digitally controlled with an accuracy of ±1°C, and the system includes an overheat protection sensor that automatically cuts power to prevent damage. The heating rate can reach up to 10°C per minute, facilitating efficient ramp-up times for various protocols.

Typical Applications
This convection drying oven is ideal for drying laboratory samples, sterilizing instruments, melting wax, and storing materials under controlled temperature conditions. It suits research and development labs requiring reliable and uniform heating for sample preparation and testing.
Configuration & Operating Notes
The oven includes two removable steel shelves. For precise temperature measurements, users should calibrate the oven using a temperature calibrating kit and set the temperature offset accordingly in the controller. Overheat protection enhances operational safety by automatically cutting power if the temperature exceeds safe limits.
