This Automatic Micro Carbon Residue Analyzer conforms to GB/T 17144, ISO 10370, and ASTM D4530 standards, delivering carbon residue measurements from 0.10% (m/m) to 30.0% (m/m). For petroleum products with carbon residue above 0.10%, results are equivalent to the Conradson Carbon method (GB/T 268, ASTM D189), while products below 0.10% require preparation of a 10% (V/V) distillation residue via GB/T 6536 (ASTM D86) before testing. The instrument features program-controlled temperature regulation, maintaining 500°C ± 2.0°C with a 15-minute thermostat hold, ensuring precise thermal conditions for reliable analysis.
The analyzer integrates automated switching flow for efficiency, one-button operation for full test automation, and a protective program that halts and alarms during abnormal furnace temperatures. It uses a stainless steel air guide pipe for low-carbon, environmentally compliant exhaust emissions, and includes an end-of-experiment alarm system. Typical applications span petroleum product testing, lubricant analysis, and quality control in refineries, where carbon residue is a critical indicator of stability and performance.
This unit is used by laboratories and testing facilities requiring compliance with international standards for petroleum and petrochemical analysis. Buyers should confirm compatibility with their specific sample types and throughput requirements, as the analyzer is designed for controlled, high-precision environments. Trade terms, including packaging and lead times, should be verified directly with Changsha Friend Experimental Analysis Instrument Co., Ltd, based in Changsha, Hunan, China.

Before ordering, verify that the analyzer’s measurement range (0.10% to 30.0% m/m) aligns with your sample requirements, particularly if testing distillate petroleum products below 0.10%, which need prior distillation residue preparation. Confirm compatibility with your laboratory’s existing workflows, including space, power, and exhaust ventilation, as the instrument uses a stainless steel air guide pipe for emissions.
Discuss logistics such as packaging, shipping, and lead times directly with Changsha Friend Experimental Analysis Instrument Co., Ltd. The analyzer’s dimensions and weight are not specified, so ensure your facility can accommodate delivery and installation. Clarify Incoterms, such as FOB or CIF, and payment terms, including any deposits or milestone payments tied to manufacturing or shipping stages.
Request quality checks such as factory acceptance testing (FAT) and calibration certificates to ensure the analyzer meets GB/T 17144, ISO 10370, and ASTM D4530 standards. Inspect the temperature control system (±2.0°C at 500°C) and safety features, including the automatic stop and alarm for abnormal furnace conditions. Ask for documentation on the stainless steel exhaust system to confirm environmental compliance.
