the Brookfield KU-3 Viscometer

The Brookfield KU-3 Viscometer is a highly precise digital instrument designed specifically for measuring the viscosity of paints, coatings, inks, adhesives, and pastes. Widely regarded as the industry standard, it combines accuracy, ease of use, and versatility, making it an essential tool for laboratories and production environments that require consistent and reliable viscosity measurements in accordance with ASTM D562.

One of the key features of the Brookfield KU-3 Viscometer is its continuous sensing and digital display, which provides real-time readings in multiple units: Krebs units (KU), grams, and centipoise (cP). This allows operators to monitor sample consistency instantly, ensuring accurate formulation and quality control. The instrument also features a magnetic spindle coupling, enabling rapid attachment and removal of spindles, which simplifies the testing process and reduces setup time.

The KU-3 Viscometer offers a wide measurement range, covering 40 to 141 KU, 32 to 1,099 grams, and 27 to 5,274 cP, making it suitable for both low- and high-consistency materials. It delivers high accuracy of ±1% of the full-scale range and reproducibility of ±0.5%, providing confidence in repeated measurements. The instrument is designed for ease of use, eliminating the need for weights and offering a user-friendly operation suitable for technicians of all skill levels. A HOLD switch allows operators to lock in test results, which can then be compared across different measurement units.

This viscometer accommodates a versatile range of sample containers, including pint, half-pint, and quart cans, and an optional paste spindle is available for testing high-consistency materials, such as roller mill pastes. Additionally, NIST-traceable viscosity standards are available to ensure accurate and industry-compliant measurements.

The Brookfield KU-3 Viscometer operates by measuring the resistance of a spindle rotating in the sample fluid. The spindle's resistance is then converted into viscosity readings, providing a straightforward yet highly reliable method for determining product consistency. The digital LED display offers high-resolution readings with increments of 0.1 KU, 1 gram, and centipoise, making the device precise and easy to interpret.

Ideal for professionals in the paint, coatings, and ink industries, the KU-3 ensures quality and consistency while streamlining the testing process. Its robust design, combined with accurate digital measurement, makes it the preferred instrument for laboratories seeking precision, efficiency, and adherence to ASTM standards.

In summary, the Brookfield KU-3 Viscometer delivers digital precision, ease of use, and reliable performance, making it an indispensable tool for quality control and product development in the coatings, paints, and inks industry.
