EZ Series Viscosity Cups

An easy and economical way to measure viscosity with ±3% production tolerance. Easily measure viscosity using an EZ® viscosity cup and a stopwatch. Simply fill the cup by immersing it in the test liquid. After withdrawing the cup, measure the time it takes until the first break in the liquid stream. Each cup is supplied with a conversion table to determine viscosity in centistokes (cSt) from the elapsed time.  Each stainless steel cup meets dimensions as specified in ASTM D 4212 standards. NIST-traceable models are available—they conform to MIL STD 5662A, ANSI/NCSL 2540-1, and are traceable to NIST-standard oils. NIST-traceable models include a certificate verifying traceability to NIST standards. Choose from five cup models according to the viscosity range required for your application. Carousel stand 08700-70 holds up to five EZ® cups—order separately. To time liquid flow, a stopwatch is also available.
