RDO-9042A（RDO-9042B）

The product casing is made of high-quality galvanized sheet and is processed into shape. The surface is treated with electrostatic spraying technology, which ensures long-term corrosion resistance and durability.
The inner liner of the box can be made of high-quality stainless steel or galvanized sheet, with rounded corners for easy cleaning.
The oversized ergonomic design of double-layer tempered glass observation window makes it convenient to observe the experimental process inside the box.
The use of a new type of synthetic silicone sealant strip results in an attractive appearance and enables long-term operation at high temperatures, with an extended service life.
Unique hot air circulation system: Utilizing low-noise self-cooling fans, this design ensures a longer lifespan for the fans and more uniform temperature inside the box.
Intelligent digital PID temperature control instrument: Equipped with functions such as timing, over-temperature alarm, temperature deviation correction, and temperature self-tuning;
After the fan is turned off, there will be significant temperature variations inside the working chamber. Under normal circumstances, the fan should not be turned off.
