Yetuo DB-XGW far-infrared graphite electric heating plate

model: DB-XGW

Product Overview:

This product is suitable for chemical analysis, physical measurement, heat treatment, baking, drying, and other temperature experiments in laboratories of industrial and mining enterprises, medical and health, environmental protection, biochemistry, scientific research and other units.

Product features of Yetuo DB-XGW far-infrared graphite electric heating plate

The shell is made of high-quality cold-rolled steel plate through sheet metal manufacturing, and the surface is treated with spray coating technology

The surface is made of high-purity graphite board, which greatly improves the anti-corrosion function and can prevent direct baking with open flames

● It has the characteristics of no open flame, no dust, fast heating, high temperature uniformity, and safety and reliability

matters needing attention:

The ambient temperature should be between 2-40 ℃, and the electric heating plate can work normally

Relative humidity not exceeding 85%

There are no strong vibrations, flammable or explosive materials, or corrosive gases around

The power supply voltage must match and be stable with the voltage required by the product

This instrument must be effectively grounded

During the first heating process, it is normal for there to be smoke and odor inside the electric heating plate, which is caused by the insulation material inside the electric heating plate at high temperatures. It will disappear after a few uses

It is normal for the surface of stainless steel material to have yellowing marks, which are caused by high-temperature debugging during factory production
