Zahn immersion cups

Zahn immersion cups 2 or 3. These Zahn cups are factory-calibrated viscometer equipments. Satisfies the ASTM D 4212 specifications, to determine the viscosity of liquids. It is commonly used in the industrial sector as well as in research laboratories. However, only low-viscosity liquids can measure with this method accurately. Because the liquids cannot pass through the nozzles if their viscosity is too high.

How to use it?

The viscosity determine on the basis of the flow rate and the time the liquid needs to pass through the nozzle from the flow cup. Viscosity measurement temperature in laboratory 20°C. The start time is when the liquid exits the flow cup at the lower edge of the nozzle. You should stop the time measurement as soon as the fluid no longer runs smoothly or stops.

When you finish your measurement, it is crucial that you clean the immersion Zahn cups for accurate viscosity check, from dried-on residues can impair the next measurement result. You should also make sure not to use pointed or sharp tools for cleaning because scratches and abrasion also affect the result.
