The Best Concrete Moisture Meter
C555
The 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.
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.

Target Your Concrete RH Testing with the C555 Concrete Moisture Meter
What is a Concrete Moisture Meter?
Our C555 effectively assesses the dryness in the top ½ inch of smooth concrete slabs. It is an easy, quick, and useful first step that you can take when evaluating a concrete slab that will be receiving some flooring finish.
“Goodbye” to the days of confusion, waste, or extra work, and “hello” to the days of saving effort, time, and money. When assessing your concrete, you want an easy and nondestructive tool to set you up for success.
The C555 does exactly that.
It is easy to use and the only concrete moisture meter in the market that allows for in-field calibration. This makes it easier to meet the calibration requirements of ASTM F2659.
It also has built-in temperature and relative humidity sensors!
Use the C555 On:
Concrete Brick Gypsum
If You Use the Rapid RH in situ Concrete RH Testing System, Think of the C555 as a Targeting Device
Imagine a device that could tell you exactly where your concrete’s most likely problem areas are. These spots might have unusually high RH levels. With the C555, you don’t have to imagine it: the device actually exists.
Consider the C555 your handy partner in conjunction with the Rapid RH System. Put these two together, and you’ve got a dynamic duo that will help you gather essential data and help you make an informed decision about where to place your Rapid RH in situ sensors.
While this meter is not meant to be used by itself for a final quantitative analysis of concrete moisture conditions, it is intended to make your job and life easier. Who wouldn’t want that?
The C555 emits a signal into the material to measure moisture down to ½ inch below the surface. Sure, the C555 is a pretty good tool for wet/dry indications on its own. But, when used with the Rapid RH testing system, the C555 Concrete Moisture Meter becomes an effective targeting system that helps you place your L6 Smart Sensors in the areas where they will be most effective.
The C555 gives you quick data about what zones are low or high in moisture. It optimizes moisture targeting and helps you get the best readings from your in situ RH testing. Not only that, but its function as a non-destructive concrete moisture meter for preliminary evaluation means that the C555 is ASTM F2659 compliant.
C555 Concrete Moisture Meter Kit contains On-Demand Calibrator
If you are ever unsure whether the C555 Concrete Moisture Meter is calibrated, an On-Demand Calibrator platform is included to allow the user to calibrate the C555 back to original factory standards in less than a minute. The calibration process is simple and fast so that the user can very quickly get back to using the C555 with as little delay as possible.
The C555 features an alarm audio sound that corresponds to a high moisture content alarm threshold, within the Standard Measurement mode, and programmable to sound the alert at readings from 0.0 to 6.9. This function is perhaps most useful when scanning a section of concrete to locate higher moisture content areas without continually looking at the digital display.
✔️ QUICK, NON-DESTRUCTIVE READINGS: The 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.
✔️ EASILY LOCATE HOTSPOTS: The C555 allows you to easily locate hotspots in your concrete slab. This information can help guide the best/vital placement of in-situ RH tests.
✔️ MONITORS AMBIENT CONDITIONS: Measures ambient temperature and humidity conditions so you can assess whether the environment is appropriate to install your floor.
✔️ MEASURES ADDITIONAL MATERIALS: Measures concrete, brick and gypsum.
✔️ RELATIVE MEASUREMENT MODE: Use the C555 in Relative Measurement mode to receive a comparative indication of moisture in materials other than concrete using a scale from 1 to 100.
✔️ BUILT IN ALARM: Utilize the C555’s alarm to get notified if moisture levels exceed set thresholds, adjustable from 0.0% to 6.9%.
✔️ BACKLIT SCREEN: Use the backlit screen for easy readability in low-light conditions.

Moisture sensor
Worked exactly as described and is very accurate. Although I don’t own another to compare it too!
Coach K –
Easy to use
I am an inspector and use it to test the moisture content of concrete slabs mostly. I have used the Tramex meter in the past. This one is more affordable so I took a chance and am happy I did. I actually like the way it works better and the accuracy seems comparable. I would definately recommend this meter.

Read Before Buying
Review: Wagner Meters C555 Pinless Concrete Moisture MeterFirst Impression: Holding this meter, it feels like a professional tool—solidly built with a protective rubber boot. The digital display is bright and intuitive. The real ‘wow’ moment was seeing how easy it is to use: just place it on the slab, and you get a reading, no fuss!Pros: The pinless technology is a game-changer; zero surface damage means faster workflow and happier clients. The readings are incredibly fast and consistent, giving me confidence in my preliminary moisture evaluations. Plus, the built-in ambient temperature and relative humidity sensors are a fantastic addition, reducing the need for multiple tools.Cons: It’s definitely an investment, so the price point might deter DIYers or those who only need occasional readings. Also, while the pinless feature is great, you still need a smooth surface for accurate contact. Heavily textured concrete can be tricky.Overall Thoughts: If you’re a pro who deals with concrete subfloors—flooring installers, inspectors, etc.—the C555 is an essential, time-saving tool. Its speed and non-destructive accuracy make it easily worth the cost over time. This tool elevates the quality of your work.Suggestions for Improvement: A protective case should be included, not sold separately, given the price. I’d also appreciate a feature to log or save a few readings internally.Recommendation: Highly recommended for professionals. Stop guessing and start knowing! This meter will save you from costly moisture-related floor failures.

Expensive investment, but the non-destructive testing is flawless
If you are looking for a reliable way to test concrete moisture without damaging finished surfaces, the Wagner C555 is the standard for a reason. While the price point is definitely high, the performance matches the cost. The biggest benefit is the pinless technology, which allows for fast, non-destructive scanning. Unlike cheaper meters, this unit scans 0.5 inches deep, giving you a consistent and accurate picture of moisture pockets below the surface without leaving a grid of pinholes behind.The usability is excellent for professional workflows. It features a scuff-resistant Teflon pad that glides smoothly over rough concrete, preventing wear and tear on the sensor. It also includes built-in sensors for ambient temperature and relative humidity, which is a massive convenience since it saves you from carrying a separate hygrometer. The included “On-Demand Calibrator” is also a great touch, allowing you to verify the unit’s accuracy right on the job site.Ultimately, you are paying a premium for the technology and brand reliability, but it works exactly as advertised. For professional applications where surface integrity and data accuracy are critical, this meter is a solid investment that does its job with zero fuss.
