ACL-2 Colorimeter For Petroleum Products - TANAKA[Mar. 10, 2010 3:02:37]
Specification
The ACL Colorimeter was designed for automatic Saybolt/ ASTM Color measurement of petroleum products utilizing the Tri-Stimulus method. No subjective judgment, plus full capability of easy and precise calibration, assures a high level traceability required by ISO 9000 series programs. Combination of high speed 16 bit A/ D converter and a low drift receiver assures extremely high accuracy. Test standards ASTM D 6045, JIS K2580.
* Tri-Stimulus Method
* High Accuracy
Traceability: No subjective judgment plus full capability of easy and precise calibration assure the high level of traceability that is required by modern quality assurance programs such as the ISO-9000 series.
Accuracy: The combination of a high-speed 16 bit A/ D converter and low drift/ high precision amplifier assures extremely high accuracy. No more guess work, especially for the tricky Saybolt color measurement.
Quicker than Spectrophotometer: A typical measurement takes a mere 9 seconds, which is considerably shorter than the time a spectrophotometer would require. ( typically 25 seconds)
User Friendly Interface:
* A dialogue type operation plus dedicated design for color measurement of petroleum products assure the easy operation. Just select the desired color scale from the menu, pour a sample in the sample cell, set it in the cell compartment, and press the START key; an accurate test result will be ready in 7-10 seconds.
* The new design sample cell takes a smaller sample volume ( 1/ 3 of the conventional rectangular cell) because of its cylindrical design. Also featured are plastic caps, which prevent sample spill when the sample cell is set in the instrument.
* Capabilities of Platinum-Cobalt color scale for solvents and Gardner color scale for varnish have been added.
Wide Selection of Options:
* Flow-through cells for easy connection to automated sample handling systems.
* Calibration Fluid Samples made according to the Appendix of ASTM D6045 for easy/ accurate calibration.
* Rectangular sample cells for easy pouring of wax samples.
