ACR-M3 Micro Carbon Residue Tester

The ACR-M3 is used in the determination of the amount of carbon residue formed after evaporation and pyrolysis of petroleum material under conditions specified in ASTM D 4530, which is intended to provide some indication of the relative coke forming tendency of such materials. The ACR-M3 offers precise control of test conditions, and requires smaller samples and less operator involvement than previous models. Up to twelve samples may be tested simultaneously, including a control sample.

  • ASTM D 4530, ISO10370
  • Excellent Repeatability and Reproducibility
  • Vinyl Laminated Trap for Easier and Safer Removal
  • One-Button Operation
  • Superb Temperature Control


Small Sample: Test can be run with a small quantity of sample (0.15 to 1.5g for small vials, 3.0g for med vials and 5.0g for large vials, depending on carbon residue content).

Easy Operation: Test automatically proceeds exactly as prescribed by simply pushing the START switch. Pressure controller (2nd stage regulator) and solenoid valve supply constant pressure. No fine tuning is required after test starts. The buzzer sounds intermittently for 10 seconds when the process is finished.

Equipped With Gas Flow Meter: With the N2Gas flow meter and needle valve fitted on the front panel, process parameters can be easily checked and calibrated.

Vinyl Laminated Trap: The condensate trap is equipped on the front of the tester. Thanks to this, the condensate volume is easy to confirm and the trap easily attaches and detaches. Trap jar is vinyl laminated for safety.

Excellent Repeatability/Reproducability:
Repeatability and reproducibility are excellent. Since the electronic temperature control is far more precise compared to that of Conradson method’s.
