The density of a coating should remain constant from batch to batch. Density Cups are used to determine the specific weight per unit volume of a liquid at a given temperature. Also known as Pycnometers or Specific Gravity Cups.
A stainless steel precision instrument for determining the specific liquid products. A tolerance of 0.1% is guaranteed. Testing is carried out in accordance with ISO at 23 ± 2°C.
This instrument consists of a cylindrical container and cover with a small escape hole for exhaust of excess liquid materials which can be removed when the cup cover is pressed tightly. This will also remove air bubbles being trapped in the liquid.
In accordance with DIN 53217, ISO 2811 and BS 3900 A19.
All models are supplied with a calibration certificate.
