Now available from Particle Test , the Koehler Penetrometer is designed to carry out ASTM penetration testing on petroleum products and consistency testing on a wide range
of food products, cosmetics, pastes and other solid to semisolid products.
Precision machined and assembled to exacting specifications, the Koehler Penetrometer features a rugged construction to ensure a long service life in both laboratory and
The Koehler Penetrometer from Particle Test features a full penetration range of 0-62.0mm with 1/10mm subdivisions (0-620 penetration scale). It accommodates cones and
needles to perform all of the ASTM tests on lubricating greases, asphalts, petroleum waxes and petrolatums.
The compact design of these penetrometers makes transport simple, while the head assembly adjusts for accurate placement of the tip of the needle or cone on the surface of the sample.
A sturdy, cast iron base provides optimal support and has a built-in spirit level and leveling screws to ensure proper alignment of these petroleum testers during operation. This penetration testing instrument is also supplied with 50 and 100g weights and a standard 47.5g plunger assembly. Koehler also offer a number of order test cones, needles and lightweight plunger (where applicable) separately.
Penetration tests are performed on petroleum products to determine consistency and shear stability for design, quality control and identification purposes.
The Koehler pentrometer works with the release of a standard cone or needle which is allowed to drop freely into the petroleum sample for 5 seconds 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.
