Japanese/English instruction manual for the Anest Iwata NK-2 viscosity cup, a simple tool for judging liquid viscosity for coating work (10–60 sec range).
This instruction manual covers the Anest Iwata (アネスト岩田) NK-2 viscosity cup (粘度カップ NK-2形), a compact tool for simply judging the viscosity of liquids used in coating work. The manual states that the cup is not a measuring instrument and that its readings cannot be applied to other purposes. It is written in Japanese with an English section (VISCOSIMETER NK-2) on page 2.
The manual explains safety precautions before use, the four-step measuring procedure using a stopwatch, cleaning after use, an approximate viscosity conversion chart, and the warranty and repair service terms, including a six-month warranty valid only in Japan.

No. The manual states it is a tool to judge liquid viscosity in a simple way and is not a measuring instrument, and its measured figures cannot be used for other purposes.
Submerge the cup in well-agitated liquid, lift it out while starting a stopwatch, and measure the seconds until the flow of liquid from the cup is interrupted. A longer time means higher viscosity.
Do not use halogenated hydrocarbon liquids such as 1.1.1-trichloroethane or trichloroethylene, as they can chemically react with the product and cause cracks. Liquids containing solids or over 60 seconds should also be avoided.
The warranty period is six months from the date of purchase and free repair applies during that period; the warranty is valid only in Japan.
