This instrument is designed and made as per industrial standard SH/T 0165-92 Standard Test Method for Distillation Characteristics of Petroleum Products with High Boiling Point Range by Vacuum Process. It is suitable to determine the distillation characteristics of wax oil, lubricating oils and other petroleum products with high boiling point range.
1. The vacuum measurement and display system is composed of high-precision pressure sensor and digital pressure gauge, which fully meets the requirements of SH/T O165-92 standard.
2. The instrument is a desktop structure, the heating power is continuously adjustable, and is equipped with a heating furnace cooling device, which can quickly cool the heating furnace after completing the test of a sample.
3.The vacuum pump is used to form a vacuum suction system. The vacuum decompression time is fast, and the maximum residual pressure is 2mm mercury column.
The main features are: use a pressure sensor and a digital meter to replace the mercury U-shaped tube to detect the negative pressure, the reading is intuitive and convenient, and the trouble of filling the mercury is solved.
