Product Description
Features
ASTM D-445-446, ASTM D2515, ISO 3104-3105 and UNE 400313 Cannon-Fenske Opaque Viscometers (reverse flow type) are used for dark Newto- nian liquids; especially suitable for liquids so dark in colour that cannot be seen in a Cannon-Fenske routine viscometer. Also used to study shearing stress and shearing rate. Sample volume: aprox. 12 ml. Precision: ±0.3%. Value indicated at 40ºC and 100ºC in both bulbs.
All capillary viscometers are supplied with the calibration certificate issued in accor- dance with the conditions of accreditation granted by a National Metrological Register which has assessed the measurement capability of the laboratory, the test uncertainty and its traceability to recognized international standards UKAS.
* We offer many types of glass capillary viscometers that are not listed in our catalog. We can also manufacture glass capillary viscometers with customer-specified constants. Viscometers with special constants, added temps, and before/after data are available by special order.

FAQs of Cannon-Fenske Opaque Viscometer:
Q: How should the Cannon-Fenske Opaque Viscometer be properly cleaned for reuse?
A: It should be thoroughly rinsed with a compatible solvent to remove sample residue, then dried in an oven as recommended. Proper cleaning ensures reliable performance and extends the viscometers service life.
Q: What types of liquids can be measured with this viscometer?
A: This viscometer is designed for both transparent and opaque liquids, making it ideal for use in industries like petroleum, chemicals, paint, food, and pharmaceuticals.
Q: When is calibration necessary, and what is required?
A: Calibration should be performed regularly or before critical measurements, using calibrated standard oils for reference, to maintain high accuracy (0.2% of reading) in viscosity results.
Q: Where can the Cannon-Fenske Opaque Viscometer be effectively utilized?
A: It is effective in laboratory settings across industries, including petroleum refineries, chemical plants, research institutions, and quality control labsanywhere precise viscosity measurement is essential.
Q: What is the measuring process with this viscometer?
A: The sample is introduced into the viscometer, which is then immersed in a temperature-controlled bath (up to 150C) to the specified depth. The time required for the liquid to flow between marks is measured visually and used to calculate kinematic viscosity.
Q: What are the main benefits of using this manual viscometer model?
A: Its opaque coating allows for the measurement of non-transparent samples, while manual operation eliminates the need for power. Reusability, accuracy, and compliance with international standards further add to its value.
