Product Details
The DHG Series Electric Heating Drying Oven is ideal for users with high demands on temperature uniformity. As essential support equipment for scientific research units, it is highly recommended for intermediate and advanced laboratories.
It is widely used in applications such as drying, sterilization, thermostatic storage, and heat treatment. However, it is not suitable for volatile, flammable, or explosive substances to avoid the risk of explosion.

Features
● Equipped with a precision LCD microcomputer intelligent PID control system, featuring temperature regulation, timing function, and over-temperature alarm. An RS485 communication interface is included. Models with a “C” designation use a standard LED digital temperature controller and do not support computer connectivity.
● The inner chamber is equipped with a high-quality brand circulation fan, with adjustable speed and air volume (not available in “C” models). The maintenance-free motor ensures long service life. Combined with a three-sided air circulation duct, it guarantees stable and uniform temperature distribution.
● Interior made of mirror-finish stainless steel with excellent acid and corrosion resistance.
● Door features a double-layer tempered glass observation window with built-in lighting, allowing clear visibility of the chamber contents.
● Adjustable shelf spacing and quantity for flexible sample placement.
● CE certified by the European Union; comes with a 2-year warranty.
