Description

The penetrometer consists of a rigid steel frame with base plate and level gauge that ensures stable and correct positioning during testing. A movable penetrometer arm with manually operated plunger release enables controlled and precise release of the penetration needle for consistent test results.

Penetration depth is measured with an analog dial gauge with a resolution of 30 × 0.01 mm, enabling precise reading of the penetration value. The system is supplied complete with a plunger of 97.5 g. An alternative plunger of 47.5 g is available as an option (article number 20-2080E30) for different test conditions and specification requirements.

The apparatus is suitable for routine quality control and laboratory testing of bituminous binders in the road and asphalt industry. Needles and other accessories are ordered separately according to test protocols.
