1.What is your max temperature?

Max 250℃, 200℃is normal.

2. Structure of the blast drying oven

The outer casings of all specifications of the drying box are made of high-quality plates and sprayed on the surface. The materials used in the working room are made of high-quality stainless steel and have 1 to 6 shelves. The insulation layer is filled with fiberglass insulation cotton. The doors and windows are equipped with double-layer high-temperature tempered glass observation windows, and a silicone sealing surface is embedded in the joint between the studio and the cabinet to ensure that the studio environment is isolated from the outside world. The operation components such as the power switch and temperature controller of the drying box are concentrated on the control panel on the left side of the front of the cabinet.

3.What is the temperature range of the DHG series blast drying oven?

Temperature setting range: -RT+10~200.0°C;
Basic error of temperature measurement: < 0.3%;

4.Why can't the laboratory blast drying oven be vacuumed?

- The vacuum pump is not the correct model specification.
- Various connecting pipes (heads) are loose, and the inner diameter is too fine
- Vacuum gauge damage
- The drying box door is not closed
- Vacuum drying oven door seal rubber aging loses elasticity
- The bleed valve and vacuum valve are connected incorrectly
