Application

The instrument is designed and made as per national standard of People’s Republic of China GB/T508,ASTM D874 and ASTM D482 Standard Test Method for Ash Content of Petroleum Products. The ash content furnace is suitable to determine ash content in the petroleum products as per GB/T508. It could not be used to determine ash content in the petroleum products containing ash-forming additives (including additives containing certain phosphorus compounds), lubricating oils containing lead, and used engine crankcase oils.

Test Procedures:

Take ashless filter paper as ignition core. Ignite the sample in the crucible to make it burning to ash and carbon residue. Heat the carbon residue at 775℃ in the high temperature furnace to make it convert to ash. Then cool down and weigh the mass.

Features
1. The Ash Content Furnace is composed of a box-type heating furnace, a temperature control stand and an electric heating plate. It is small size and needs less land. 
2. The box-type furnace adopts all-in-one structure. Special fire-resistant material and heating components. The heating time is short and it has a long lifetime.
3. An adjustable LED temperature controller is equipped in the control stand. The overshoot is small and temperature control is stable. 
4. The size of heating plate is Φ85mm. Small size and good durability.
