DataMaster™ L6 is for manual and automatic on-site monitoring
Floorcloud™ for the True Remote Monitoring SystemWhy Relative Humidity Testing?
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.

Saves Us Time, Money, and Effort
The Rapid RH® is inexpensive, quick and easy to use, and enables us to do calibration checks required for ASTM F2170 compliance in seconds rather than hours. And because it gives us quick, accurate results, we can address a potential problem quickly. Or, if there’s no problem, we can get back to the install without further delay. This saves us time, money, and effort.
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” readings to help with detection of moisture pockets. It’s also a helpful tool for anyone wanting to perform concrete surface moisture testing.
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.
