Concrete testing equipment measures the strength and consistency of concrete material and evaluates its quality for use in existing structures or new construction. Cylinder molds are used to take and store concrete samples and assess the compressive strength of the hardened concrete over time. Maturity meters measure changes in temperature over time to evaluate the strength of new concrete. Slump testing products measure the consistency of fresh concrete before it sets, usually between loads. Rebar locators determine the location, depth, and size of rebars and other metals under the surface of the concrete.
