Manufacturer: BYK-Gardner USA Brand: BYK-Gardner Model: 7901

The BYK-Gardner 7901 Brookfield-type rotational viscometer has a 15 to 2,000,000 centipoise (cP) viscosity measuring range and measures the dynamic viscosity of a fluid based on the force required to stir the fluid. Its auto-ranging LED display shows viscosity in centipoise (cP) and millipascal seconds (mPa s), percentage torque, spindle used, and rpm, and a rotary switch allows selection of 18 speeds. It accepts 220V input power. The viscometer is accurate to 1 percent and results are repeatable to 0.2 percent.The model LVDV-E viscometer includes a set of four spindles, lab stand, carrying case, and operating instructions. This Brookfield-type rotational viscometer is suitable for testing a variety of fluids, such as oils, gases, polymers, cosmetics, detergents, and foods for use in a variety of industries.

A viscometer, also called a viscosimeter, is an instrument used to measure the friction caused by the relative motion of a Newtonian fluid and a known surface, and is usually expressed in units of poise (P), centipoise (cP), pascal seconds (Pa s), and millipascal seconds (mPa s). Viscometers have several forms, including but not limited to falling ball, rotational, vibrating, capillary, funnel, and bubble. A falling ball viscometer measures the time it takes for a ball of known diameter and density to fall through fluid in a cylinder of known diameter. A rotational viscometer measures the force required to stir a fluid. ...

These durable, portable systems allow you to make quick visual comparisons between your sample and a range of stable colored glass standards on a disc. Battery operated illuminator offers flexibility for laboratory, plant, or field color grading. With the two-section field of view, the sample transmittance is directly compared with individual colored glass standards on a test disc. The comparator is ideal for light-colored samples with visual color (pathlength up to 40 mm); an illuminator is added to systems for measuring unsaturated samples requiring a longer pathlength. Color scales Pt-Co/Hazen/APHA What's Included: discs containing colored glass filters, sample cells/tubes, calibration filter with certificate, and three AA batteries (for illuminator models). Economical, visual color measurement in laboratory, plant, or field Available with the most popular color scales Simply place sample in vial and compare transmittance to glass color standards
