he Rapid RH® moisture testing system

T

should be used on any project where
moisture-sensitive floor coverings or coatings
are to be applied over concrete slabs. Owners,
general contractors, flooring contractors/
installers, and testing companies need to be
sure the tests they perform are accurate,
repeatable, and available to all who need
to know the current moisture condition of
concrete slabs.

apid RH® significantly improves your

R

project team’s ability to instantly test and/
or monitor the drying progress of a concrete
slab without adding substantial cost to the
project. The Rapid RH® enables you to take
fast, accurate periodic readings that fully
comply with industry standards. The Rapid
RH® Smart Sensors are factory-calibrated
and use CMOSens® technology to ensure the
sensor’s accuracy and fast equilibration.

Step 1: Drill the Hole

Step 2: Clean the Hole

Correct hole depth and hole diameter are important in complying with the ASTM
F2170 standard (see RH Testing Best Practices section on page 24). For easy
installation of a Smart Sensor and/or Base Sleeve, a uniformly round hole is important.
Drill a hole in the concrete slab to the required depth using a rotary hammer drill and a
¾”-diameter masonry drill bit. Per the ASTM F2170 standard, drill the hole to a depth
equaling 40% of the slab’s thickness for slabs that are drying from one side, or 20%
depth for a slab drying from two sides. For proper Rapid RH® 5.0 installation, be sure

to position the drill perpendicular (90˚) to the surface being tested.

TIP: If you do not have a depth gauge for your drill, mark or tape-off your drill bit to the
correct depth setting.

Attach the vacuum attachment to the straight extension of a shop vacuum cleaner

hose* and thoroughly vacuum up the dust in and around the hole.

Next, insert the wire bristle brush into the hole. Turn the brush several times to loosen
pulverized concrete from the walls of the hole. Vacuum again. Repeat this step twice
to ensure no loose concrete particles remain in the hole.

IMPORTANT: Correct Diameter and Hole Uniformity: Use the ¾”-diameter section
of the black insertion tool as a diameter and uniformity gauge to ensure a correct and
uniformly round hole. If the ¾”-diameter section of the tool will not go easily into the
hole, the drill bit may be out-of-spec (worn out, etc.) or the hole may not have a uniform
diameter from top to bottom. Not performing this step may cause damage to a Smart
Sensor and/or Base Sleeve when attempting insertion.

*The vacuum attachment may require an adapter depending on vacuum model.

Step 2: Clean the Hole (Cont.)

Step 3: Insert Smart Sensor/Base Sleeve

Directly out of the package, the Smart Sensor/Base Sleeve combination is 1.6” in length
or 40% of a 4” thick slab. ASTM F2170, Section 10.2 states: “Slab drying from top only
(example: slab on ground with vapor retarder below, or slab on metal deck): 40%
depth. Slab drying from top and bottom (example: elevated structural slab not in metal
deck): 20% depth.” Each Smart Sensor/Base Sleeve pack includes a number of short
(0.4”) extensions that can be inserted into the Base Sleeve to enable use in thicker
slabs. Adding one extension increases the Base Sleeve length to 2” for testing 5” thick
slabs to the 40% depth. Keep any unused extensions for future jobs. If needed, you

can use additional extensions to increase the length
of the Base Sleeve for thicker slab applications.

In summary, add one extension insert to a Base
Sleeve for every 1” increase in slab thickness over 4”
to meet the 40% depth requirement. The extension

inserts make the Base Sleeve’s usage exible for

varying thicknesses of concrete.

If this is the rst time you will be using your

5.0 system, take a Smart Sensor/Base Sleeve
combination directly out of the package, and with no
extensions installed, insert it into the hole using the
insertion tool with red cap placed atop for ease in
pushing down on the insertion tool. Push down on
the insertion tool with cap to insert the Smart Sensor/
Base Sleeve combination into the hole, “seating” it at
the bottom (review the IMPORTANT hole diameter
and uniformity comment under Step 2). Under
no circumstances should you tap or hammer the
insertion tool during insertion. Doing so may cause
damage and will void any warranty.

protective cap into the top of the Base Sleeve, and push the cap down to the concrete
surface. Or, if testing in thicker slabs, assemble the proper number of extensions, and
with the protective cap inserted into the top most extension, push down the extensions
and cap into the hole to the concrete surface, until fully seated on the Base Sleeve,
completing the installation. At this point, if you have installed the Smart Sensor and
the Base Sleeve, remove the protective cap and, utilizing the Sensor Extraction Tool,
remove the Smart Sensor from the Base Sleeve, replacing the cap into the Base
Sleeve. (More details in Step 5: Remove the Smart Sensors, page 17.)

Remember: Correct depth of the hole is critical to adhere to the ASTM F2170 test
method. (See the RH Testing Best Practices section on page 24.)

Caution: NEVER use your reader device (either the Smart Reader or the Easy
Reader) to install the Smart Sensor and/or Base Sleeve.

The standard Rapid RH® Easy Reader (with LCD display) or
the Rapid RH® Smart Reader with Bluetooth® (in conjunction
with the DataMaster™ app available for Apple and Android
devices) can be used.

IMPORTANT NOTE: The Rapid RH® 5.0 version allows for reuse
of the 5.0 Smart Sensors from job to job. Using the standard Easy
Reader or the Smart Reader (in conjunction with the DataMaster™
app), you can obtain readings, move sensors from one test hole
to another, and manually document and provide your own F2170­compliant reports (Rapid RH® sensor packs and kits come with
location grid documents and report templates to make it easy to
manually document your testing. Additional copies can be obtained
at rapidrh.com).

Using the Smart Reader and DataMaster™ app, you have the ability
on a job to store each sensor’s readings and/or upload them to
Wagner’s f2170reports.com website for more automated and easier
generating of compliant reports.

“Leapfrogging” of a sensor from location to location on a job can be
time-consuming. You are encouraged to have enough 5.0 Smart
Sensors to cover the quantity of test holes required for your largest
jobs. If you have a very large project requiring far more 5.0 sensors

the required tests.

After proper acclimation of the capped off environment within the Base Sleeve (currently
at least now 24 hours per the ASTM F2170 standard) return to the jobsite, remove the
protective cap from the Base Sleeve and reinstall the Smart Sensor utilizing the Sensor

Extraction tool. Once you have rmly seated the Smart Sensor at the bottom of the

Base Sleeve, replace the cap, and after one hour you can begin to periodically (every 15
minutes or so) take readings, until you have assurance that the Smart Sensor has fully
equilibrated, and is providing stable relative humidity and temperature values. NOTE:

This time is a general guideline. Please refer to the ASTM standard for specics.

approximately 5 minutes or until the Easy Reader is reinserted into another Smart
Sensor. NOTE: During the toggling of the readings, when the cursor is next to the
%RH symbol, the value shown is the in-hole relative humidity reading; when the
cursor is next to the °F or °C symbol*, the value shown is the in-hole temperature.

The Rapid RH® Smart Sensor’s patented design equilibrates (acclimates) faster than any
other concrete relative humidity sensing device. Project scheduling decisions regarding
the slab can usually be made one hour after installation. Just remember to follow the
ASTM F2170 procedures pertaining to minimum equilibration time for correct and required
reporting of the test results.

AN IMPORTANT COMMENT ON SENSOR SERIAL NUMBERS:

Whether it is a 5.0 (reusable) or 4.0 (single use) device, every Rapid RH® Smart

Sensor has a barcode serial number label on the outside of the Base Sleeve when you

rst pull it out of the factory packaging. ASTM F2170 documentation has stipulations

for documenting sensor serial numbers for moisture testing on your jobs, so keeping

track of sensor serial numbers is important for report documentation and verication

labels are included if an original barcode serial number label or original Base Sleeve

gets damaged.

NOTE: Fresh out of the factory packaging, a 5.0 Smart Sensor assembly consists of

three discrete parts: 1. Base Sleeve (with barcode serial number); 2. A nned-base

section, and; 3. The actual Smart Sensor that has already been inserted at the factory

into the Base Sleeve, and therefore associated with that serial number label on its

original Base Sleeve.

The actual Smart Sensors can be removed from their original Base Sleeves (if the

sleeve gets damaged from use, etc.), but attempt to keep the original Base Sleeve

RH Testing Best Practices

New concrete slabs should be allowed to cure
and dry for as long as possible before performing
any type of moisture testing. Even though some
methods state to wait at least 28 days after a

test locations and obtaining the nal results per testing standards, then it is good
practice to set a few new tests to conrm and validate what the older test locations are

currently indicating. For sensors experiencing 95% RH for longer durations of time, an

upward drift up to a few percentage points may be experienced.
concrete pour before setting up test instruments,
it is often prudent to wait much longer.* Minimizing
the amount of time between initiating any moisture

testing on a slab and obtaining the nal results

per testing standards increases the chance that
the test results will more accurately indicate the
condition of the concrete around the test location.

Additionally, it is good practice to let the sensors lie on the slab for about 10 minutes or

so prior to installation, until they reach temperature equilibrium with the slab to prevent

any dew point issues that might cause condensation on or around the sensor (NOTE:

Wagner has not heard of any reports where this has actually been an issue, but it is

still a best use practice). For more information on relative humidity in concrete oors

and moisture testing, go to www.cement.org to order the book “Concrete Floors and

Moisture” by Howard Kanare.
On all slabs (new and old), it is recommended to do
test sampling, prior to completing testing, according
to the ASTM F2170 standard’s requirement, in
regards to the number of test sites. It is good
practice to initially only set up a portion of the test
locations ultimately required and use those few
locations as a means to indicate when the rest of
the tests should be performed. If extended periods
of time have elapsed between initially setting up

*The drying rate of standard Portland cement-based concrete slabs has been studied extensively. For

slabs drying from one side, a very general rule-of-thumb as a drying rate is approximately 30 days of drying

time for each inch of thickness of the slab for the relative humidity level to reach somewhere in the 85%-

90% range. This is only a very rough approximate guideline, and drying times can, and often are,

much longer if good drying conditions (closed-in space, environmental controls on, etc.) are not present.

Additionally, other factors such as the densifying of a slab surface from heavy power-troweling, additional

water added to the concrete at time of pour, rain, or construction water sitting on a slab, etc., can drastically

affect the drying time of a concrete slab.

The ASTM F2170 standard mandates measuring RH at service conditions. But your

project’s timeline may be such that you’d like to be able to estimate RH before reaching

service conditions.

Wagner Meters offers a simple-to-use, science-based RH estimator tool that adjusts

for service temperature. The easiest way to use this handy tool is with the Rapid RH

DataMaster™ app, available for both iOS and Android devices. The estimator tool is

also available online at wagnermeters.com/rhtemp where you can also watch a short

introductory video for more information.

Simply obtain the RH and temperature readings of your concrete slab with your Rapid

RH®, then use the DataMaster™ app, the online estimator tool, or download the service

temperature adjustment table to get an estimated RH value at service conditions.

Note: The service temperature adjustment tool was developed by CTLGroup, a wholly-owned

subsidiary of the Portland Cement Association.
