Zahn Viscosity Cups determine the flow time of paints, coatings, enamels, oils and other similar liquids. A conically shaped steel cup delivers 44 cc’s of liquid sample through a precision orifice. A twelve inch looped stainless steel handle allows the cup to be dipped by hand into a liquid container. At the top of this handle is a stainless steel split key ring for aligning the cup in a true vertical position when conducting tests.

• All stainless steel cup and handle
• S90 Signature Zahn Viscosity Dip Cups are an improved version of the time honored Zahn Signature viscosity cups
• Calibration of the S90 Zahn cups match the earlier Zahn Signature cups
• Conversion formulas and tables relating cup efflux time in seconds to viscosity in centistokes are identical for both series of cups
• Qualify for certification under ANSI/NCSL Z540-1 or MIL-STD-45662A, as applicable
• Calibrated with standard "G" series oils traceable to the National Institute of Standards & Technology ("G" series calibration oils are produced in accordance with ISO 9002)

NOTE: Efflux time from these cups does not meet ASTM specifications, but tables are available for converting S90 Zahn cups efflux time to EZ™ Zahn cup efflux time which complies with ASTM D 4212.
