The Wagner C555 Concrete Moisture Meter 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.
With its built-in ambient sensors and included On-Demand Calibrator, the C555 comes with everything you need to perform the test as outlined in ASTM F2659.
What It Is For
Built-in sensors measure ambient temperature and relative humidity.
The On-Demand Calibrator allows fast, easy user calibration.
The relative mode can be used on other materials such as concrete blocks.
Use it to survey a slab quickly and find the wettest areas before you commit to in-situ testing, or to track a slab drying down after a water loss.
Important: A Survey Meter, Not the Final Test
ASTM F2659 is a preliminary, comparative method. Wagner states the C555 does not replace in-situ relative humidity testing to ASTM F2170. Where a flooring manufacturer, an Australian flooring standard or a specification calls for an RH test before laying a floor, use in-situ probes such as the Wagner CFP405 Rapid RH L6 Concrete Flooring Professional Kit and Rapid RH L6 Smart Sensors. The C555 tells you where to put them.

Operating Advice
Check calibration with the paired On-Demand Calibrator before each job.
Test on smooth, firm, clean concrete. Remove coatings, adhesive residue and loose material from test spots.
Hold the sensor pad flat and fully in contact with the surface.
Scan in a grid and record readings with the ambient conditions, so you can compare areas and visits.
Mark the highest readings for in-situ RH testing.
Frequently Asked Questions
Can I sign off a slab for flooring with the C555?
Not on its own where an RH test is required. It is a survey tool. Follow the flooring manufacturer's or specification's test method.
What does the 0 to 6.9 reading mean?
It is Wagner's concrete moisture scale for the top 13 mm of the slab, used to compare areas. It is not a relative humidity figure.
Will it read through tiles or vinyl?
Wagner designs it for smooth, firm concrete. Relative mode can compare other materials, but readings through floor coverings are not a concrete moisture reading.
Can I use it on timber?
No. Wagner does not calibrate it for wood species. Use a wood moisture meter.
