C555 Handheld Concrete Moisture Meter Kit with Backlight

The C555 is a concrete moisture meter that can help locate problem areas in the case of a moisture-related incident. Depending on the manufacturer, you can use the C555 to determine if flooring installation is ready to install, or as a way to enhance your RH probe installation.

The C555 evaluates to ½ inch below the surface, making it a valuable tool for moisture conditions of concrete, gypsum cement, or other floor slabs and screeds. It can be used to identify pockets of high moisture levels to determine the readiness of a flooring installation depending on the manufacturer or as a supplement to the Rapid RH sensors.

Yes, the C555 can measure ambient temperature and humidity levels, helping you ensure your job site is at optimal conditions. It's like having a moisture meter and a Smart Logger all in one!

Wagner Meters conducted an in-house case study, evaluating the accuracy of the C555 Concrete Moisture Meter against the top leading concrete moisture meter manufacturers, across nine varied and commonly used concrete mix designs in the United States.The graph provided illustrates the average moisture meter error when testing these specific mix designs. Our findings were compelling: the C555's readings were consistently closer to the benchmark oven-dry results compared to others, solidifying its status as twice as accurate as the leading concrete moisture meters.
