ACO-7 Automated Cleveland Open Cup Flash Point Tester

Model ACO-7 is the latest version of the automated Cleveland Open Cup(COC) flash point tester from Tanaka. When this seventh generation model was designed after 35 years of providing automated flash point testers to the petroleum industry, ease of operation and maintenance was sought.
Model ACO-7 Asphalt Version is a new addition to the latest version of the automated Cleveland Open Cup(COC) flash point tester from Tanaka. While maintaining the features of the regular ACO-7 flash point tester, a unique skimmer was added to automatically remove the surface skin that forms on the sample when bitumen or some other samples are tested. Surface skin removal has been known to improve the precision and the safety of the COC flash point testing of such samples, and some test methods including JIS recommend it.



While data processing functions such as data storage and statistical analysis can be added to the automated flash point testers, these functions were excluded from the standard specification, since it was found that very few users would use these functions and the addition of such extra functions could make the operation of the regular flash point determination complicated.

Single Action Setting: The flash detector rings and the temperature sensor are permanently mounted on a swing-arm assembly, which allows easy setting of the specimen.

Easy Operation: Select a test mode and enter the expected flash point; while the instrument executes the test, you are free to do other lab work. The tester follows the exact procedures prescribed in the test method, and the completion of the test cycle is signaled by beeps. The test result is brightly shown on the VFD module.

Auto Fire Point Detection: In addition to the flash point, fire point can be determined automatically. The fire point is detected when the double ionization rings detect 5 sec of continuous burning.

Auto Fire Containment: ACO-7 is equipped with a fire containment lid which activates automatically to help extinguish the fire when ACO-7 detects a fire point or specimen is burning heavily.

Modular Design: The tester consists of a computer control unit and a test head unit, allowing remote placing of the test head unit up to 3 meters away. An optional Changeover unit can be purchased to attach the control unit to another type of flash point test head unit (APM-7 or ATG-7). The control unit is designed to control any of the three different flash point test head units, one at a time.
