Overview
QND-4C viscosity cup is a kind of viscosity cup designed with Benchtop structure. The upper part is cylindrical and the lower part is conical. It is suitable for measurement of outflow time range from 0 to 150s. The QND-4 viscosity cup is designed and manufactured according to the national standard GB/T 1723-93. The viscosity measured is the conditional viscosity, which is the time for a certain amount of sample to flow out of a specified diameter hole under certain temperature conditions. Expressed in seconds (s), it is suitable for measurement of viscosity of coatings, paints viscosity and other related products.
Features
1. Benchtop structure design, the upper part is cylindrical, the lower part is conical container
2. Measurement range of outflow time 0~ 150s
3. The copper cup body is used, and the metal cup shall prevail.
4. Flow hole diameter 4mm, capacity 100ml
5. Flow hole length 4 +/- 0.02mm
Principle
QND-4C viscosity cup measured by the measurement of a certain amount of sample at a certain temperature conditions from a predetermined diameter hole outflow time condition viscosity, in seconds (s) expressed viscosity value.
Applications
Coatings, paints viscosity measurement, other related products viscosity measurement
Steps
1. Prepare the sample and control the temperature conditions
2. Pour the sample into the viscosity cup
3. Measurement of the time for the sample to flow out of the specified diameter hole
4. Record the outflow time, indicating the viscosity value in seconds (s)
Notice
• Sample temperature conditions need to be controlled during measurement
• Measurement range of outflow time is 0~ 150s
• The metal cup shall prevail, this model is a copper cup body.
• The diameter of the flow hole is 4mm and needs to be kept clean
