Summary of Method
Penetration tests are performed on petroleum or other products to determine consistency and shear stability (lubricating greases) for design, quality control and identification purposes. A standard cone or needle is released from a penetrometer and allowed to drop freely into the sample for 5 seconds (or a different specified interval) at constant temperature. The depth of penetration of the cone or needle into the sample is measured in tenths of a millimeter by the penetrometer."
- Designed for ASTM penetration tests on petroleum products and for consistency tests on a wide range of food products, cosmetics, pastes and other solid to semi-solid products.
- Precision machined and assembled to exacting specifications, and ruggedly constructed to insure long service life in both laboratory and field applications.
- Features a full penetration range of 0-62.0mm with 1⁄10mm subdivisions (0-620 penetration scale).
- Accommodates cones and needles to perform all of the ASTM tests on lubricating greases, asphalts, petroleum waxes and petrolatums.
- Compact design facilitates transport for field use.
- Head assembly adjusts for accurate placement of the tip of the needle or cone on the surface of the sample.
- Sturdy cast iron base provides excellent support and has a built-in spirit level and leveling screws to insure proper alignment of the penetrometer during testing.
- Supplied with 50 and 100 gram weights and standard 47.5g plunger assembly.
- Order test cones, needles and lightweight plunger (where applicable) separately.
