C555 Preliminary Slab Testing and Sensor Placement

Concrete moisture meter readings from the Wagner Meters C555 help you locate problem areas before placing Rapid RH L6 Smart Sensors. The handheld instrument takes non-destructive preliminary readings 0.5 in into smooth, firm concrete. Flooring installers and concrete contractors can compare readings across a slab during an initial moisture survey. Built-in sensors measure ambient temperature, relative humidity and dew point, so you can check surrounding conditions while scanning the floor.

C555 Slab Scanning and Field Calibration

The C555 takes preliminary slab measurements and ambient readings. Its built-in ambient sensors and included paired On-Demand Calibrator cover the test outlined in ASTM F2659. The calibrator lets you calibrate the meter in the field, and the meter comes with a 1-year warranty.

  • Locate areas for further testing — Scan 0.5 in into the slab to find moisture problem areas and decide where to place Rapid RH L6 Smart Sensors.
  • Read the concrete scale correctly — The concrete moisture range is 0.1 to 6.9 on a concrete scale. These readings are not percentages of moisture content.
  • Keep a reading visible — The press-to-hold button locks the measurement on screen while you record it.
  • Flag high readings audibly — Set the programmable high-moisture alarm and adjust its volume to hear alerts as you check the floor.
  • Calibrate in the field — Use the paired On-Demand Calibrator supplied with the kit to calibrate the C555 moisture meter.
  • Check concrete-like materials — Select relative measurement mode to check materials such as concrete block on a 0-100 scale.

C555 Applications for Flooring and Building Assessments

Flooring installers can use this concrete moisture meter to survey smooth, firm concrete, gypsum cement and other floor slabs and screeds before choosing locations for in-situ sensors. On jobs in offices, schools or retail facilities, concrete and flooring contractors can use the readings to identify areas that need further testing. Restoration contractors and building inspectors can record ambient temperature, relative humidity and dew point alongside slab readings during building assessments. Facility managers can hold readings on screen while taking notes. The C555 also works with the Wagner Meter Reach Extender accessory.

Frequently Asked Questions

How Does the C555 Differ from Rapid RH In-Situ Testing?
The C555 takes non-destructive preliminary readings 0.5 in into the slab. These readings help locate problem areas and guide placement of Rapid RH L6 Smart Sensors for in-situ testing.
Will the C555 Read Wood Flooring or Lumber?
No. The C555 is not calibrated for wood species and cannot be used to measure wood moisture.
Which Surfaces Can the C555 Test?
The C555 tests smooth, firm concrete, gypsum cement and other floor slabs and screeds. Use relative mode for concrete-like materials such as concrete block.
How Is the C555 Calibrated?
Use the included paired On-Demand Calibrator to calibrate the meter in the field. NIST-traceable calibration with a certificate is available as a separate purchase.
What Battery Does the C555 Use?
The C555 uses a 9V battery. Alkaline, lithium or rechargeable NiMH cells all work. A battery is included. Battery life depends on use; the meter has a low-battery indicator and automatic power shut-down after 60 seconds.
Does the C555 Have a High-Moisture Alarm?
Yes. The C555 has a programmable high-moisture alarm with adjustable volume.
