Standard Test Method for Density and Relative Density (Specific Gravity) of Liquids by Bingham Pycnometer. The standard determine s density / relative density (specific gravity) of liquids.

The measuring principle  is based on a calibrated glass bottle with capillary

 Density determined from:

• Mass of liquid
• Precisely known volume

The method requires tight temperature control

It is mainly used for:

• Gasoline
• Jet fuel
• Naphtha
• Light petroleum distillates
• Other low-viscosity liquids

Designed for low-viscosity liquids

Typically used for products with:

• Vapor pressure not too high
• Kinematic viscosity generally below ~15 mm²/s at 40 °C

Measurement is usually done at:

• 15 °C
• 20 °C
• 25 °C

The test uses a Bingham pycnometer, a specialized glass density bottle designed for viscous materials.

Temperature control is critical because density changes significantly with temperature.

Common test temperatures:

• 15 °C
• 20 °C
• 25 °C
• 40 °C
• 100 °C (for some heavy materials)

The method requires a constant-temperature bath with tight stability.

The Tamson TV2000 is designed for ultra-precise temperature control. The TV2000 is able to achieve a temperature stability of 0.01°C. The TV2000 is maintenance free and designed to run with minimal operational costs. The TV2000 can be operated from ambient +5 up to +230°C (..446°F).

With the use of the built-in cooling coil, sub ambient temperatures down to +5°C can be achieved. Optionally, the bath can be equipped with a Z41 backpanel illuminator to improve visibility. 

The TV2000 is available in the following voltages/frequencies:

• TV2000 230V/50-60Hz (P/N: 00T0782)
• TV2000 115V/60Hz (P/N: 00T0784)
