Concrete Penetrometers allow rapid in-place estimates of the concrete initial set. After the initial set, concrete can no longer be effectively consolidated and is nearly ready for final finishing operations. These convenient field devices yield approximate results of standard ASTM or AASHTO test methods.
Gilson's penetrometers feature penetration plungers with 0.05in² (32.3mm²) surface area and scribed marks to indicate 1in (25.4mm) penetration. Each model can also be adapted with an optional 2.7in (68.6mm) diameter penetration foot to evaluate mortars for unit masonry.
