The Density of a coating should remain constant from batch to batch. Also known as Density Cups or Specific Gravity Cups, Pycnometers are used to determine the specific weight per unit volume of a liquid at a given temperature.

The Elcometer 1800 Density Cup is a stainless steel precision cup for determining the specific gravity or density of paints and similar products.

The Pycnometer consists of a cylindrical container and lid with a hole for the exhaust of excess liquid.

How to use a Density Cup:
• Weigh the Cup and Lid when empty
• Fill with the liquid
• Place lid on the Cup, removing excess liquid*
• Weigh the Density Cup when full
• Divide the weight by the cup volume/capacity to determine the Specific Gravity

*Each Pycnometer has an escape hole in the lid to allow excess liquid to escape. Any excess liquid should be removed before weighing.

The Elcometer 1800 Density Cup Stainless Steel can be used in accordance with Test Methods:

• ASTM D 891-B
