How it Works

The KU-3 Viscometer operates by measuring the resistance of a spindle rotating in the sample fluid, held in standard paint industry cans. The spindle’s resistance is converted into a reading in Krebs units, grams, and centipoise, allowing for accurate and repeatable measurements. The instrument’s lever offers two positions:

• Up: Spindle stationary, drive motor off
• Down: Spindle rotating, sample being measured

A HOLD switch is available to lock in the test results, which can then be compared across the different measurement units.

APPLICATIONS

• Paints
• Coatings
• Adhesives
• Inks
• Pastes
