Penetration Resistance Testing
Penetration resistance testing can range from soils and concrete to soft fruit and gels. It can be a feature of mechanical strength in construction, but equally a feature of texture analysis, as with food and cosmetics. Mecmesin specialises in sample bench testing, from a few mN up to 50 kN, but our hand-held instruments include the Shotcrete Penetrometer for assessing the curing rate of sprayed concrete. Standardisation of test methods involves choice of probe, which can be a needle, a blunt probe of given diameter, or a cone of given angle. Using a motorised universal tester, the penetration rate can be precisely controlled, and the pattern of penetration to a given depth recorded in detail.
