Description
Penetration Strength Tester is a portable non-destructive testing (NDT) instrument designed to evaluate the compressive strength of in-place concrete using the penetration resistance method. The instrument measures the penetration depth of a hardened steel test nail driven into the concrete surface and accurately correlates the penetration depth with the concrete’s compressive strength using standardized strength conversion curves.
The tester operates on a lever-operated spring loading mechanism, where a working spring is compressed to store energy and then instantly releases it to drive the measuring nail into the concrete. This simple yet reliable method enables rapid, economical, and repeatable strength assessment while causing only minimal surface damage.
Designed for construction sites, quality control laboratories, and engineering inspections, the Penetration Strength Tester provides a quick and effective solution for evaluating in-situ concrete strength without the need for destructive core sampling.
