Changsha Friend Experimental Analysis Instrument Co., Ltd. offers a carbon residue analyser that implements the Micro Conradson method in Changsha, China. The instrument meets GB/T 17144, ISO 10370 and ASTM D4530, and can measure carbon residue from 0.10 % up to 30.0 % (m/m). For samples below 0.10 %, the analyser evaluates a 10 % v/v distillation residue prepared according to GB/T 6536 (ASTM D86).
Temperature control is achieved through a programmed automatic system that maintains a constant furnace temperature throughout the test. Flow switching is fully automated, allowing rapid sample introduction without manual valve handling. A single‑button operation drives the complete test cycle, and an integrated safety module stops the furnace and sounds an alarm if abnormal temperatures occur. The exhaust pipe is constructed from stainless steel, providing a low‑emission, durable air guide.
The analyser is suited for laboratories testing fuel oils, lubricants and petrochemical intermediates that require compliance with international residue standards. Buyers such as refinery quality‑control labs, fuel testing agencies and research institutes typically request this equipment. The listing does not disclose pricing, minimum order quantity or delivery lead time; these details should be confirmed directly with the supplier. Importers should agree on Incoterms, payment terms and arrange for calibration support before shipment.
