Model TO-512

Universal Penetrometer

Penetrometers are used for testing a wide variety of materials such as grease, petroleum, bitumen, tar, asphalt, rubber, cement and soils.

In this test, a chosen force is applied over a given area for a known period of time and the depth of penetration or the depression made in the sample is measured in tenths of a millimetre, which is expressed as a penetration number. An accurately fabricated steel base has been designed to facilitate penetration tests to be made over a wide surface area of sample. Adjustable feet are provided in the base for levelling. The display and penetration arm are adjustable to permit the testing of samples immersed in a thermostat bath.

The unit is compact with in-built timer to control the duration of penetration, which is preset in the factory to five seconds. The instrument is provided with levelling screws. Each penetrometer is supplied with a plunger weighing 47.5g for testing bituminous product, one 50g weight, and one 100g weight. It also includes the cone and Penetration Unit.
