Tanaka ACR-M3 Automated Micro Carbon Residue Tester

ACR-M3 Micro Carbon Residue Tester

ACR-M3 is a tester to be used for the determination of the amount of carbon residue formed after evaporation and pyrolysis of petroleum material under certain conditions and is intended to provide some indication of the relative coke forming tendency of such materials.

About Micro Carbon Residue Test: 

A weighed quantity of sample is placed in a glass vial and heated to 500℃ under an inert (nitrogen) atmosphere in a controlled manner for a specific time. The sample undergoes coking reactions and volatiles formed are swept away by reported as a percent of the original sample as “carbon residue (micro).” Micro Method offers advantages of better control of test conditions, smaller samples, and less operator attention compared to Conradson Carbon Residue test to which it is equivalent. Up to twelve samples may be run simultaneously including a control sample.

Test Methods:

ASTM D4530, ISO 10370 etc.

Features include:

• Test can be run with a small quantity of sample


• Easy operation


• Equipped with gas flow meter


• Vinyl laminated trap


• Excellent repeatability/reproducibility
