What is the better choice for vacuum oven?

See this problem, it is estimated that many people will certainly choose to choose their own, then what is the right for their own? First of all to know what kind of vacuum oven, respectively, set the temperature in the number of degrees? This combination of their own needs Buy for your own oven.

①, steam heating type vacuum oven is used for the range of 50 ~ 120 ℃, the use of dry temperature below 50 ℃ is not ideal.

②, hot water cycle heating vacuum oven is used for the room temperature ~ 80 ℃, the control temperature is more accurate, will not cause damage to the material, is the ideal low-temperature vacuum oven equipment.

③, electric heating vacuum oven is used at room temperature + 20-300 ℃, the control temperature is more accurate, is the ideal high and low temperature vacuum oven equipment.

④, the thermal oil heating vacuum oven is used at room temperature +20-250 ℃, the control temperature is relatively accurate, the main use of high cost, need to replace the annual heat transfer oil, and easy to heat oil leakage will cause pollution to the surrounding environment and equipment We understand the four different heating methods, we can be very clear to determine our material is suitable for what kind of heating method for heating.
