Overview
The TQC VF2185 immersion ISO viscosity cup is a Handheld viscosity testing instrument imported from the Netherlands, dedicated to viscosity measurement of Coatings, paints and other products. The product is designed according to DIN EN ISO 2431 standard, made of aluminum alloy, with a filter diameter of 5mm, suitable for rapid viscosity assessment in laboratory environments.
Features
1. Design and production according to DIN EN ISO 2431 standard
2. Made of aluminum alloy
3. Equipped with stainless steel filter
4. Each viscosity cup is engraved with a unique serial number
5. Handheld design for easy operation
6. Suitable for Newtonian or approximate newtonian fluid testing
Principle
Viscosity is calculated by measuring the time it takes for the liquid to flow out of the Hole under the viscosity cup. During the test, the time from the beginning of the flow of the liquid to the first stop of flow is recorded, and then the flow time is converted into dynamic viscosity units by the disc viscosity calculator, so it is also called the flow cup.
Applications
Coatings, paints, inks, pigments
Standards
DIN EN ISO 2431
Steps
1. Ensure that the temperature of the liquid to be tested is stable at 23 +/- 0.2 ° C
2. Adjust the liquid temperature as required
3. Choose the appropriate viscosity cup model according to the estimated viscosity range
4. Slowly immerse the viscosity cup in the liquid until the top edge is submerged
5. Put in the thermometer to measure the sample temperature
6. Remove thermometer
7. Hook your finger on the handle ring and lift the cup vertically to start timing.
8. Stop timing when the liquid beam breaks for the first time
Notice
• Temperature fluctuations during testing must not exceed +/- 0.2 ° C
• Keep vertical when lifting the viscosity cup
• The viscosity cup should be kept within 15cm above the liquid surface after leaving the liquid surface
• Timing starts when the cup leaves the liquid level
• The end of the timing is subject to the first interruption of the liquid
• It is necessary to use a viscosity conversion disc for unit conversion
