PLTL-90 Density of Greases and Highly Viscous Liquids by Pycnometer

Equipment manufacturers often specify lubricant requirements by volume. When using grease or viscous lubricating oils, measuring volumes may be messy and difficult. This test determines density, which allows operators to make simple mass/volume conversions.

The sample is placed in a specially designed aluminum pycnometer, and brought to the test temperature. The sample mass and volume are accurately determined and results are reported in grams per cubic centimeter.
