Gilson’s Mortar Penetrometers are hydraulic or spring-reaction devices that perform well in a lab or field and used in determining set times of concrete mixes, prepared mortars, and grouts by measuring penetration resistance. Resistance is plotted to determine initial (500psi) and final (4000psi) setting times.
Each model is supplied with six standard stainless steel penetration needles in bearing areas of 1, 1/2, 1/4, 1/10, 1/20, 1/40 in² (645, 323, 161, 65, 32, and 16mm²), used for testing samples at regular intervals.
