Vacuum drying oven can provide proper temperature and vacuum environment. It can do vacuum drying or thermal test under vacuum condition in the field of electrical and electronic, aviation and others. The vacuum drying oven can perform low pressure tests independently, and can perform comprehensive tests with high temperature.

Features:

▲ PID+SSR temperature control;

▲ Hysteresis error pressure control;

▲ The air pressure can be as low as 1 kPa;

▲ Independent over-temperature protection system.

Remarks:

1. If the laboratory is sensitive to oil mist, oil mist traps can be used. You can also connect the exhaust pipe by yourself and remove the oil mist from the laboratory.

2. When the test sample contains more water, the vacuum pump needs to be changed to the type with gas ballasting. When drying, open the gas ballasting.

3. When drying the samples, if organic matter such as oil mist evaporates, it can use a cold trap to adsorb organic matter onto the surface of the cold trap, in order to avoid organic matter entering the lubricant of vacuum pump.
