C555 Handheld Concrete Moisture Meter Kit with Backlight


WAGNER C555 Handheld Concrete Moisture Meter Kit provides fast, non-destructive preliminary moisture measurements on smooth, firm concrete to help pinpoint problem areas and determine where to place Rapid RH® L6 Smart Sensors. Built-in sensors measure ambient temperature and relative humidity.

The included On-Demand Calibrator allows fast, easy user-calibration. A NIST-traceable version, with a certificate of calibration, can also be purchased. With its built-in ambient sensors and On-Demand Calibrator, the C555 comes with everything you need to perform the test outlined in ASTM F2659. Relative mode can be used on other materials such as concrete block.

How does a concrete moisture meter work?
A concrete moisture meter sends a signal from the sensor pad down into the concrete. The meter reports the moisture level based on a capacitance equation calibrated specifically to measure within concrete materials.

Concrete moisture meters are non-destructive and do not require drilling or driving pins into the concrete. However, they are not designed to be used to determine the moisture condition of a concrete slab when flooring material will be installed over it.

The C555 complies with ASTM F2659 to provide a preliminary evaluation of comparative 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 optimum placement of Rapid RH® L6 Smart Sensors.
