The ADU 5 is designed for the distillation of petroleum products and volatile organic sample liquids in standardized boiling point groups for the examination of; Motor gasolines Aviation gasolines Aviation turbines fuels special boiling point spirits Naphthas White spirits Kerosines Gas oils Distillate fuels oils Solvents and similar petroleum products The aim of the distillation is a determination of the distillation curve at atmospheric pressure. The device conducts program-controlled distillation tests with programmable boiling point groups and automatically controlled heating rate. A light barrier system records the curve of the volume increase of the distillate during the time interval. After ending the distillation,the boiling point curve is displayed and recorded
