The Elcometer 1800 Densimeter, also known as a pycnometer, density cup or specific gravity cup, is a stainless steel precision cup for determining the specific gravity or density of paints and similar liquids. Coating density should remain constant from batch to batch, so measuring the weight per unit volume of a liquid at a given temperature is a straightforward way to check formulation consistency and catch a batch that is off specification.
The cup is a cylindrical container with a lid that has a hole to let excess liquid escape. In use, the empty cup and lid are weighed, the cup is filled with the liquid, the lid is fitted so that excess runs out, and the full cup is weighed; dividing the weight by the known cup volume gives the specific gravity. The range covers two volumes and two supply options: the Elcometer 1800/1 (K0001800M001) at 50cc and the Elcometer 1800/5 (K0001800M005) at 100cc, with the 1800/2 (K0001800M002) and 1800/6 (K0001800M006) supplied with a calibration certificate.
The density cup can be used in accordance with test methods including ASTM D1475, ASTM D891-B, ISO 2811-1 and JIS K 5600-2-4, the recognised methods for liquid coating density. It is used in paint and coatings manufacturing and quality control laboratories. Supplied by BAMR, South Africa's authorised Elcometer distributor.
Elcometer 1800 Densimeter / Picnometer / Specific Gravity Cups
The Density of a coating should remain constant from batch to batch. Also known as Density Cups or Specific Gravity Cups, Picnometers are used to determine the specific weight per unit volume of a liquid at a given temperature.
- Elcometer 1800 Density Cup Stainless steel precision cup for determining the specific gravity or density of paints and similar products.
- Picnometer design 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.
When to use the Elcometer 1800 Density Cups
Use the 1800 when you need to confirm that a coating's density stays constant from batch to batch. The stainless steel picnometer holds a fixed volume of liquid so you can weigh it and calculate specific gravity at a given temperature. It conforms to ASTM D 1475, ISO 2811-1 and DIN 53217-2 among others.
- 1Verify batch consistencyDensity should remain constant from batch to batch, and the cup gives the specific gravity figure that flags a formulation or mixing problem early.
- 2Fixed-volume measurementThe cylindrical container and lid with an exhaust hole hold a known volume, so weighing full and empty and dividing gives specific gravity directly.
- 3Stainless steel precisionThe stainless steel cup is built for repeated weighing of paints and similar liquids, suiting routine quality control to the referenced standards.

Frequently asked questions
What is the purpose of the Elcometer 1800 Density Cup?
The 1800 is a picnometer used to determine the specific weight per unit volume (density) of a liquid coating at a given temperature. Density should remain constant from batch to batch, so the cup is used as a quality control check on coating material.
What volumes and materials are available for the Elcometer 1800?
The 1800 is available in 50 cc and 100 cc volumes, both in stainless steel construction. Each volume can be ordered without a certificate (M001 or M005) or with a calibration certificate (M002 or M006).
When would I need the calibration certificate version of the Elcometer 1800?
Calibration certificate variants (K0001800M002 and K0001800M006) provide traceable records where these are needed for quality management systems or customer audits. The non-certificate versions are suitable for routine in-process checks.
