Direct-reading instrument for precision penetration measurements of bituminous materials, cement, petrolatum and waxes, as well as food, cosmetics and pharmaceutical products. Unit has 5" diameter indicator dial, graduated in 400 divisions of 0.1mm, corresponding to 40mm penetration. Zero preset to eliminate errors. Includes 47.5g plunger with 3.2mm hole, and two loading weights (50g and 100g).
Penetration tests are performed on petroleum 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.
Features and Benefits:
• Conforms to ASTM and related specifications for penetrometers
• Suitable for laboratory or field use
It is used for finding out rate of hardening of mortars sieved from concrete mixtures. The instrument consists of a barrel housing a calibrated spring and a stem graduated from 0-70 kg X 1 kg. six interchangeable penetration needles of areas 645,323,65,32 and 16mm sq. are provided. The penetration resistance is measured by the force exerted to penetrate the mortar by 25mm and is indicated by a sliding ring on the stem, which is graduated . Needle shanks are marked at every 12.5mm. compete in a wooden carrying case.
