I. Summary
The instrument is designed and made as per the industrial standard of People's Republic of China SH/T0165-92 Test Method for Distillation of High Boiling Point of Petroleum Products at Reduced Pressure. It is suitable to determine the distillation characteristics of high boiling point petroleum products, such as wax oils, lubricating oils, etc.
II. Main technical features
1. This instrument is desktop structure. It is composed of distillation test part and vacuum process part. It can meet requirements of SH/T 0165
2. The power of the heating furnace can be adjusted continuously. It equips a cooling device to make the heating furnace cooled down rapidly after determination. It is convenient for next test.
3. The vacuum pump has good effect. The max residual pressure is 2mmHg.
