For successful flooring projects, it is crucial to measure moisture below the surface of the concrete slab. Other tests
are surface-based and do not give reliable results. For example, the anhydrous calcium chloride test measures only
the moisture vapor emission rate coming from the slab’s surface. It tells you nothing about the moisture condition
deeper in the slab. Only the in situ relative humidity (RH) test is scientifically proven for accuracy and reliability. Learn MoreRapid RH L6 Overview
Enhance the Effectiveness of Your Concrete RH Testing with the C555 Concrete Moisture Meter
The C555 Concrete Moisture Meter assists with optimal placement of ASTM F2170 concrete slab RH test probes by enabling preliminary "Wet/Dry"
measurement readings to help with detection of moisture pockets.
The C555 Concrete Moisture Meter supports the most effective placement of Rapid RH L6 Smart Sensors according
to the processes outlined in ASTM F2659. Also, the built-in temperature and relative humidity sensor will give you
ambient readings to assist with your ASTM F2170 reporting. Using the C555 as a qualitative measurement device,
you can also get an instant indication of moisture intrusion within materials such as brick, concrete, and gypsum. Buy C555 NowLearn More

“The process behind the Rapid RH is solid. We went to Rapid RH because the accuracy is certified and it doesn’t
need to acclimate past its initial point. We could stick [the sensor] in there, read it and trust it.”
