Summary
This instrument is designed and made as per standards GB/T6536 Test Method for Distillation Characteristics of Petroleum Products and ASTM D86 Standard Test Method of Distillation for Petroleum Products at Atmospheric Pressure. It is suitable to determine the distillation characteristics of gasoline, aviation gasoline, jet fuels, solvent having special boiling point, naphtha, diesel oil, distillate fuels, and other petroleum products.

This instrument is a kind of double-units instrument which the minimum temperature of the condenser pipe can reach 0℃.It is an ideal distillation tester for petroleum products under low temperature condition.

I. Main Technical Features
1.The instrument adopts low temperature and double units working mode. The minimum temperature can set to 0℃.It can do test for one sample or two samples at same time.It highly improves the work efficiency.
2.It adopts digital temperature controller, stainless-steel heater, new type refrigeration compressor and electric stirrer to constitute constant temperature bath. The temperature in the bath is uniform,can fully meet the requirements of test.
3.It adopts special designed structure, cooling speed is fast.The bath temperature can cool down from room temperature to 0℃ within 50 minutes.
4.It adopts special heating furnace to ensure the safety of test. Heating power can be stepless adjusted to meet the requirements of test.
