Facing this question, it is estimated that a lot of people will say that definitely choose the right for their own, then what is the right for their own? First of all, we need to know what kinds of vacuum oven are there,what temperature points can be set respectively? then combine these with their needs to buy their own oven.
1.Steam heating type vacuum oven temperature range is 50~120℃, <50℃ temperature control is not ideal to users.
2.Hot water circulating heating vacuum oven temperature range is 80℃~ RT, 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 use range is RT+ 20-300℃, control temperature is more accurate, is ideal high and low temperature vacuum oven equipment.
3.Heat-conducting oil heating vacuum oven temperature range is RT+ 20-250℃, the control temperature is more accurate, the cost is high, need to replace the heat-conducting oil once a year, and heat-conducting oil easy leakage will cause pollution to the ambient environment.
When we understand above these four different heating methods of vacuum oven, we can clearly determine which heating mode our are suitable for heating.
