WindsorProbe System HP™

The Windsor Probe System HP™ rapidly and accurately determines the concrete compressive strength of a structure by driving a probe into the concrete with a known amount of force. Improved and enhanced over thirty years, this modern system is capable of measuring concrete with a maximum compressive strength of 17,000 PSI (110MPA).

V-MeterMk IV™


The V-Meter Mk IV™ is widely used and accepted for quality control and inspection of concrete, ceramic, rock and wood. It can measure and correlate concrete strength to standard strength measurement, permitting non-destructive testing of complete structures. It will identify honeycombs, voids, frozen concrete, cracks and other nonhomogenous conditions in concrete. It can locate area's of rot and decay in wood. It can also locate cracks in ceramic and rockes. A wide range of transducers are available.
