An ash-testing system for petroleum products using controlled sample combustion and high-temperature ashing. The system comprises a chamber resistance furnace and an electric heating furnace for preparing and ashing the sample residue.
Features
- Designed for petroleum ash testing to ASTM D482.
- Digitally controlled chamber resistance furnace.
- Ashing temperature of 775 ±25°C.
- Separate electric furnace for sample combustion.
- Adjustable electric-furnace heating output.
- 50 mL and 100 mL porcelain crucible sizes.
Applications
Petroleum-product ash determination; fuel quality control; laboratory research. Excludes phosphorus-additive products, leaded lubricants and used engine crankcase oil.
