V. Measuring Systems
V.1 Measuring Directly in the Sample Container
You may immerse the measurement system directly into a container of sample by removing the
cap on the bottom of the immersion cups.
When using the double gap bob measuring system, do not damage the “O” ring which forms the
seal between the inner and outer parts of the sample cup. To clean, the inner section is removed
by unscrewing the (stainless steel) ring at the bottom and then GENTLY push the inner section
out through the bottom of the outer section. Take care not to damage or stretch the O-ring seal
during removal! Insert the inner part again and screw the ring back on.
General steps for direct immersion of the measuring system into the bath:
Lift the coupling sleeve of the measuring bob coupling (the ring is visible).
Insert the measuring bob into the measuring bob coupling.
Lower the coupling sleeve (the ring is covered).
Fasten the measuring cup at the measuring cup mounting fl ange with the measuring cup
ring.
Immerse the measuring cup into the substance up to the ring mark or up to the point where
the diameter of the measuring cup increases.

Do not get sample in or onto the measuring bob coupling.
After making your viscosity measurement, unscrew the measuring cup ring and remove the
measuring cup. Open the measuring bob coupling, and remove the measuring bob.
Clean the measuring cup and measuring bob carefully. Do not use abrasive cleaning tools, and
always prevent scratches! Store measuring bobs on a soft pad.
