Features of operation:FULL COMPLIANCE WITH METHODOLOGYDiesel fuels are required to be certified to international standards. These specificationsrequire kinematic viscosity to be measured in accordance with ASTM D445, IP71, or ISO3104. The RHEOTEK AKV-diesel strictly adheres to these methods, complying in everyrespect.Compliance to ASTM D 445 is achieved by using a glass capillary viscometer tube (ASTMUbbelohde design), in an automated assembly with each step of the method preprogrammed. This removes the possibility of deviating from the method, as well asensuring the most precise results.The powerful AKV-diesel software package records all flow time measurements and statesthe precision obtained for each result. Full traceability of measurements is provided.PRINCIPLE OF OPERATIONThe RHEOTEK AKV-diesel uses ASTM Ubbelohde viscometer tubes tomake precise flow time measurements. Each tube is independentlycalibrated with a certified constant, using calibration data produced bythe PSL ISO 17025 accredited laboratory. Samples are loaded into theviscometer, via the unique RHEOTEK filling station. An internal pumppushes the sample up into the capillary tube to position it formeasurement.The sample is released and the flow time is automatically measured bythe NiR optical detectors. On completion of the first run, the sample isonce again pushed up into the capillary tube, and a second consecutiveflow time is measured. The AKV-diesel software will then calculate thekinematic viscosity result.SAFE VACUUM (IN-SITU) CLEANING AND DRYINGOn completion of the measurement process, the AKV-diesel will automatically use a “safevac”system to clean and dry the Ubbelohde viscometer tube using suitable solvents. Thewaste sample and solvent is taken to a waste container, and the system is air dried,leaving it ready for the next sample.OPTIONSSeveral options are available for the AKV-diesel,including the RHEOTEK Smart Sampler. Thiscomprises of a XYZ auto sampler with disposable vials.Up to 52 sample positions.
