Designed and manufactured by Dalian Instrument Factory in strict accordance with the Chinese national standard GB/T 511 (Determination of Mechanical Impurities in Petroleum Products and Additives), this gravimetric instrument is purpose-built for accurately measuring solid contaminants in oils, fuels, and chemical additives.
The system integrates two functional modules: a precision temperature control unit and an independent refrigeration system.
Smart digital display controller ensures stable, accurate thermal regulation.
Transparent, large-capacity circular fiberglass bath allows full visibility of the sample.
All-stainless-steel stirring device with spiral primary and auxiliary heaters provides uniform temperature distribution, corrosion resistance, and an attractive appearance.
Ring-shaped fluorescent tube mounted beneath the bath improves observation conditions, significantly enhancing visual reading accuracy during tests.
Powered by an imported compressor for long service life and low noise operation.
Supports density measurements at multiple temperature points, giving users the flexibility to test under various conditions.
