Portable Viscosity Measuring Cup (NK-4)

This NK-2 viscosity measuring cup: 3.5mm Precision Orifice – Equipped with a Ø3.5mm ±0.05mm orifice suitable for measuring flow times from 20 to 100 seconds. This NK-4 viscosity measuring cup: 4.0mm Precision Orifice – Equipped with a Ø4.0mm ±0.05mm orifice suitable for measuring flow times from 25 to 150 seconds. To perform a measurement, fill the cup with the sample liquid, cover the orifice, then release and start timing until the first break in the fluid stream. The measured flow time represents the viscosity of the liquid.

• This NK-2 viscosity measuring cup is designed for practical and accurate flow-time testing of liquids used in spraying, coating, and painting processes. Featuring a precisely machined 3.5mm orifice and a 50ml volume, the cup provides consistent and repeatable results in both laboratory and field environments.
• NK-4 Viscosity Measuring Cup – Designed for practical and accurate flow-time testing of liquids used in spraying, coating, and painting processes. Featuring a precisely machined 4.0mm orifice and a 100ml volume, the cup provides consistent and repeatable results in both laboratory and field environments.
• Standard Design – Built according to the commonly used flow-cup structure for measuring liquid viscosity in coating and spray applications.
• Durable Nickel-Plated Brass – The cup is made from nickel-plated brass for corrosion resistance, stability, and long service life.
• Simple & Reliable Operation – Fill the cup, block and release the orifice, then use a stopwatch to record flow time for quick viscosity evaluation.
