Overview
The TQC immersion viscosity cup VF2071 is a viscosity measurement tool with a long handle, made of aluminum alloy cup body and stainless steel filter. This product is suitable for viscosity detection of most coatings. Precision and convenience are provided by immersing the viscosity value in the coating with one hand operation. Model VF2071 offers 2mm filter diameter and complies with DIN 53211 standard. It is widely used in Coatings, inks and other industries.
Features
1. Long handle design, support one-handed operation, convenient measurement
2. Aluminum alloy cup body and stainless steel filter, durable material
3. Precision viscosity measurement, effectively control the viscosity value
4. Provide a variety of models to meet the needs of different viscosity ranges
5. Compliant with DIN 53211 standard, with strong industry applicability
Principle
The TQC immersion viscosity cup is lifted by immersion in the Coating and filled with liquid, and the time for the liquid to flow out of the filter is measured to determine the viscosity value. When the viscosity cup leaves the Coating surface, the timing is stopped when the liquid beam is cut off for the first time, and the viscosity range is calculated according to the flow time.
Applications
Coatings, inks
Standards
Approximate to DIN 53211
Steps
1. Ensure that the temperature of the liquid to be tested is 23 +/- 0.2 ° C and keep the temperature stable
2. Adjust the liquid temperature if necessary
3. Choose the appropriate TQC immersion viscosity cup model according to the estimated viscosity range
4. Coating the viscosity cup slowly until the top edge is submerged
5. Put in a thermometer to measure the sample temperature
6. Remove thermometer
7. Finger hook the handle ring, keep it vertical, quickly lift the viscosity cup and start timing, the cup body is kept no more than 15cm above the sample surface
8. Stop timing when the liquid beam stops flowing for the first time
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 after use
• Use soft cloth when cleaning, avoid wire brush or sandpaper
• Do not tap directly when disassembling the cup nozzle, use the auxiliary pin and heavy object.
• Make sure the cup nozzle and viscosity cup are clean before installing the cup nozzle
• Put back the box when not in use
It is recommended to calibrate once a year
• Regular maintenance to ensure experimental accuracy
