Overview
The TQC Specific Gravity Cup VF2099 model is made of stainless steel with a volume of 100ml and a weight of 198g. It is used to determine the specific gravity of Coatings and other similar substances. It is suitable for uninflated specimen density. The product is lightweight and durable, suitable for testing at 20 ° C +/- 0.5 ° C environment.
Features
1. The upper cover has a small hole with a slope to the top center, so that excess sample material can be overflowed without bubbles, increasing accuracy.
2. Provide a variety of models of 50ml, 100ml, stainless steel and aluminum.
3. Large cylindrical opening design, suitable for plastic density testing and paints inks Coating specific gravity testing.
4. All models are provided with a calibrated certificate.
Principle
Specific Gravity Cup Calculates the density of the liquid by accurately measuring the weight difference between the empty and filled cups, combined with the known volume. Operation is performed at 20 ° C +/- 0.5 ° C thermostatic to ensure test accuracy.
Applications
Plastic density test, paints specific gravity test, inks specific gravity test, Coating specific gravity test
Standards
ISO 2811、DIN 53 217、ASTM D 1475
Steps
1. Weigh out the clean drying Density Cup weight and record it.
Maintain the Density Cup and the tested liquid within a specific Temperature range (20 ° C +/- 0.5 ° C).
3. Inject the liquid into the Specific Gravity Cup.
4. Cover the lid smoothly.
5. Avoid generating bubbles.
6. Carefully wipe the spilled liquid clean with an absorbent cloth.
7. Weigh the weight of the Specific Gravity Cup filled with liquid.
8. Calculation density: density = (full cup weight g - empty cup weight g)/Specific Gravity Cup volume ml.
Notice
• Ensure Specific Gravity Cup is clean and drying before operation.
• The test process needs to be carried out in a thermostatic environment of 20 ° C +/- 0.5 ° C.
• Avoid bubbles when injecting liquid.
• Smooth operation is required when closing the cup lid.
• Spill liquids need to be carefully wiped with an absorbent cloth.
