ACR-6 Carbon Residue Tester

The ACR-6 Conradson Carbon Residue Tester automates the evaporation and pyrolysis of the oil sample in preparation for determination of the Conradson value for percentage of carbon residue remaining, and is intended to provide some indication of relative coke-forming propensities. Optimum heater output for the prescribed burning process is programmed easily prior to the test. Ignition is determined by sheathed thermocouple. Test standards ASTM D 189, IP 13, ISO 6615.

  • Programmable Burning Specs
  • Testing per ASTM D 189, ISO 6615


Easy Operation: Optimum heater output for the prescribed burning process is programmed easily prior to a test. Once a test starts, no further adjustment needs to be done.

Temperature Monitoring System: As needed, with a thermocouple placed at the crucible, temperature can be monitored to obtain a constant temperature during the last 7min of process.

Easy To Clean: Oven unit cover, control unit cover, hood and large Iron crucible with cover are made of stainless steel. Not only easy-to-clean but also durable.

Modular Design: Oven and controller are separated so that only the oven unit needs to be installed in a fume hood. (Optional connecting cable is required.)
