Overview
TQC Specific Gravity Cup model VF2098 is a professional tool for measuring the specific gravity of coatings and other similar substances, suitable for uninflated specimen density testing. Made of high-tensile aircraft aluminium alloy treated with anodic oxidation, the product is lightweight and durable, with an optional thermostatic device.
Features
1. The upper cover is designed with a small hole from the slope to the center of the top, so that the excess sample material can overflow without generating bubbles, improving Test accuracy
2. Available in 50ml and 100ml volumes, as well as stainless steel and aluminum models
3. Large cylindrical opening design, suitable for plastic density test and paints inks Coating specific gravity test
4. All models are provided with calibrated certificate
Principle
Calculate the density value of the measured liquid by accurately measuring the weight difference of the empty cup and the weight difference after filling the liquid, combined with the known cup volume. The test needs to be carried out in a thermostatic environment of 20 ° C +/- 0.5 ° C to ensure the accuracy of the measurement results.
Applications
Coating specific gravity test, inks density test, plastic density measurement, similar substances specific gravity measurement
Standards
ISO 2811、DIN 53 217、ASTM D 1475
Steps
1. Weigh out the clean drying Density Cup weight and record
2. Keep the Density Cup and the tested liquid in the 20 ℃ +/- 0.5 ℃ Temperature range
3. Inject Liquid into Specific Gravity Cups
Step 4 Cover the lid smoothly
5. Avoid creating bubbles
6. Carefully wipe the spilled liquid with an absorbent cloth
7. Weigh the Specific Gravity Cup weight filled with liquid
8. Calculation density: density = (full cup weight g - empty cup weight g)/Specific Gravity Cup volume ml
Notice
• The test needs to be carried out in a 20 ℃ +/- 0.5 ℃ thermostatic environment
• Avoid bubbles during operation
• Ensure Specific Gravity Cup is clean and drying before use
• Be careful when wiping spilled liquids
• Strictly follow the operation steps to perform the measurement process
