Overview
QND-4B coated 4 viscosity cup is a Benchtop Viscometer of YONGLIDA brand, using aluminum cup body, volume is 100ml, pore diameter is 4mm. The product is strictly designed according to GB/T1723 standard and is widely used in Coatings, paints, inks, Paints, Gloss oil and other industries. It can be used with brackets to improve measurement Stability and accuracy.
Features
1. Aluminum material, light and durable
2. Pore diameter 4mm, volume 100ml, in line with standard specifications
3. Can be used with bracket to improve measurement Stability and accuracy
4. Correction factor range 0.97~ 1.03 to ensure Measurement accuracy
Principle
Coating 4 viscosity cups calculates viscosity by measuring the time required for a fluid to flow out of a 100 ml volume from a standard pore size (4 mm). Fluid outflow time is proportional to viscosity, and accurate results can be obtained in combination with a correction factor.
Applications
Coatings, paints, inks, Paints, Gloss oil
Steps
1. Prepare viscosity cup and fluid to be tested
2. Ensure that the Ambient Temperature is within the range of 25 +/- 2 ° C
3. Pour fluid into viscosity cup to 100ml scale
4. Record the time required for the fluid to completely flow out of the aperture
5. Apply the correction factor to calculate the final viscosity value
Notice
• Ensure that the Ambient Temperature meets the requirements of 25 +/- 2 ° C before use
• Avoid cup bumping to prevent aperture deformation from affecting accuracy
• Clean the cup body in time after measurement to prevent residue from clogging the aperture
• The correction factor needs to be verified within the range of 0.97 to 1.03
