DST.321 Automated Distillation Instrument

The DST.321 is a high-tech distillation testing instrument that integrates mechanics, optics, and electronics into a single automated system. Built with a German-made JUMO temperature sensor, it ensures precise control of distillation rate, recovery volume, and accurate detection of the initial boiling point, dry point, and atmospheric pressure.

The instrument features automatic atmospheric pressure correction, fire extinguishing, bath temperature control, and complete automation of the entire distillation process. With stable performance, intuitive operation, and intelligent management features, it is an ideal analytical tool for transformer oil testing in laboratories and industrial environments.
