By utilizing the latest microwave and microprocessor science, the Cementometer can determine the water/cement ratio of freshly mixed cement, concrete, and mortar. Simply insert the prongs of the probe into the material to be measured and instantaneously the water cement ratio is shown on the easy to read display.
