Overview
The TQC VF2003 DIN cup is a DIN Benchtop Flow rate viscosity cup with a replaceable filter design. Simply purchase different diameter filters to meet the testing needs of different viscosity ranges and save costs. The cup body is made of titanium anodic oxidation aluminum, and the cup holder and nozzle are made of stainless steel. It meets the DIN53211 standard and is suitable for testing the viscosity value of paints, varnish and Miscellaneous liquids.
Features
1. The annular groove design of the cup mouth can store overflowing liquids
2. Dimensions can be used with TQC viscosity cup bracket
3. Easy to clean, cup walls and outflow holes without difficult to clean sinkage
4. Consistent quality control in the production process
5. Each viscosity cup is engraved with a unique serial number
Principle
The DIN cup determines the viscosity value by measuring the time it takes for the liquid to flow out of the standard aperture. During the test, the liquid flows out of the outflow hole at the bottom of the cup at standard temperature, and the outflow time is proportional to the viscosity of the liquid.
Applications
Paints, varnishes, Miscellaneous liquids
Steps
1. Ensure that the temperature of the liquid to be tested is 25 ° C and the fluctuation does not exceed +/- 0.2 ° C
2. Choose the appropriate pore size viscosity cup according to the estimated viscosity range
3. Adjust viscosity cup to horizontal position
4. Cover the outflow hole and inject the liquid to be tested until the liquid level exceeds the edge of the cup mouth
5. Glass drawing plate to move excess liquid into overflow ring and close DIN cup
6. Ensure that the distance between the outflow hole and the recovery liquid level is greater than 100mm
7. Open the outflow hole and remove the Glass drawing plate to start timing
8. Record the time of the first interruption of the liquid beam
Notice
• Clean the outflow hole to remove residue and avoid scratching the inner surface
• It is a precision appliance and should not be dropped or hit.
• It needs to be cleaned in time after use
• Use soft cloth when cleaning, do not use wire brush or sandpaper
• Do not tap directly when disassembling the cup mouth, use the equipped pin rod
• Make sure the cup nozzle and viscosity cup are clean before installing the cup nozzle
• Put back the original Encasement box when not in use
It is recommended to calibrate once a year
