Product Overview
The A1290 Petroleum Products Ash Content Tester is designed for determining ash content in petroleum products in accordance with ASTM D482, GB/T 508, GB/T 2433, and SH/T 0067 standards.
The instrument utilizes a high-temperature muffle furnace to completely combust petroleum samples and determine the non-combustible inorganic residue (ash content). Accurate ash determination is essential for evaluating contamination levels, additive residues, metallic compounds, and overall product quality in fuels, lubricants, crude oil derivatives, and other petroleum products.
Featuring a three-side heating furnace structure, high-efficiency ceramic fiber insulation, and precise temperature control, the A1290 delivers uniform heating, rapid temperature rise, and reliable testing performance for routine laboratory analysis.
