Density（Specific Gravity）Cups
Paint specific gravity cup (density cup) for coating, paint, ink density test. Available in 50ml, 100ml, aluminum & stainless steel, meets ASTM standard.
Description:
The Density of a coating should remain constant from batch to batch. Also known as Density（Specific Gravity）Cups. Specific Gravity Cups are used to determine the specific weight per unit volume of a liquid at a given temperature.
A stainless steel precision instrument for determining the specific weight of paints and similar products. A tolerance of 0.1% is guaranteed. Testing is carried out in accordance with ISO at 23±2℃.
This instrument consists of a cylindrical container and cover with a hole for exhaust of excess liquid for any excess Paint（or Ink）to be removed when the cup cover is pressing tightly. By doing so, will also ensure that no air bubbles（or pockets of air）are being trapped.
It is in according with DIN 53217,ISO 2811,BS 3900 A19.
Technical Parameters:
