Concrete density gauge

PEM® Solution

PF30™

Description

This customer manufactures gauges that measure the density of poured concrete. These gauges are used outside at construction sites and therefore require a tight environmental seal. The previous design would sometimes allow over-compression of the gasket, and moisture would then enter the gauge. This extended shank of this special PF30 prevents the over tightening of the assembly and allows the gasket to function properly.
