Proline Concrete C575 Features:
Your Wagner hand-held concrete meter was designed
using electromagnetic wave technology, to make
fast assessment of moisture condition in concrete
easy and inexpensive. Large areas can be surveyed
quickly and easily. Wagner meters are nondestructive; they do not require drilling or driving
pins into the concrete.
They deliver information to the user instantly.
The C575 is designed to give an average moisture
indication of everything within a specific area and
depth penetration. Electronics inside the C575
converts the signal reading, which will appear on
the analog dial. This unit requires a 9-volt
alkaline battery, which is supplied. Replace
battery when “Low Battery” light comes on.

Calibration of the meter can be checked by placing
the meter on a flat, clean, metal surface at least 1/8
inch (3.2 mm) thick, such as a car or truck hood or a
file cabinet. Press hand meter sensor firmly on
surface, the reading should be 18 plus or minus 1.
The C575 is a rugged instrument, which will give
many years of service if used with care and properly
maintained. Clean the meter case with a soft rag
lightly moistened with water. Do not subject the unit
to temperatures in excess of 125 degrees F (52°C).
Always store in a cool dry place.

Meter Storage:
For a long service life, it is important to store
your meter properly. Avoid excessively hot or
cold locations, and keep the meter in the case
provided. Do not store the meter in an area with
excessive electro-magnetic interference, such as
near an electric motor, or where it could be
crushed, such as in front of a forklift.
To Operate:
Press and release the ON button. Take readings by
pressing the bottom of the meter to the concrete
surface. The meter will automatically shut off
after 60 seconds of inactivity. The shutdown
timer will reset anytime the meter reading changes
or the ON button has been pressed.
Taking a Reading:
1. The surface of the concrete should be brushed clean
of loose debris and dust.
2. Turn on the meter and verify that the “Low
Battery” light does not illuminate.

3. Place the sensor of the meter on
the area
of the concrete to be tested.
Press down firmly, making sure
the sensor rests flat against the
concrete.
4. On a rough surface take a number of readings close
to one another. If the readings vary, use
the highest reading. On a normal smooth surface
it is also recommended that you take a number
of tests close to one another and use the highest
reading. Always refer to the adhesive and/or floor
covering recommendations for the acceptable
moisture condition of the concrete.
5. Moisture readings in concrete may be affected
by the following factors:
• The type of aggregate used in the mix may
contain iron or other metals. This could cause
the reading to be high or read the same value
no matter where you place the meter.
• A rebar or metal screen too close to the
surface will cause a high reading. Move the
meter to several areas for more comparisons.
5
Interpreting the Reading:
Readings must be evaluated relative to the purpose
for which they were taken. You must determine the
readings, which work best for the products you install
or apply. Always refer to the adhesive and/or floor
covering recommendations for the acceptable
moisture condition of the concrete.
This meter is designed for easy operation and to
provide a quick, initial indication of the moisture
condition. The meter does not measure the amount
of free water (the water that leaves during the curing
stage) in the concrete or the pounds of water per
square foot, etc. The information provided by meter
readings is affected by a number of variables so the
readings must be evaluated on the basis of
professional knowledge and the user’s skill and
judgment. After using the unit for a short period
of time, the user will be able to take a reading and
predict whether or not further testing is needed.
to accept the products being installed or applied.
If manufacturer requires further testing, use the meter
to determine the best locations for placement of the
manufacturer’s suggested test. Further testing
methods such as relative humidity may also be used if
higher accuracy is desired, even if the manufacturer of
the material does not require it.

Establishing Concrete Baselines:
Sub-Floor Installation Suitability for
Wagner
Concrete Meters
Wagner Concrete Meters detect moisture in concrete
and provide a relative reading, not a percentage of
relative humidity, moisture content or lbs./1000 sq.
ft. (kg. / 304.8 sq.m.)
You can establish your own baseline or comfort range
reading for use with the Wagner C575 meter. Once
established, the baseline will become your “not-toexceed” reading, indicating sub-floors that you cannot
safely install your adhesives, paints or floor coverings
over. You can easily establish your own baseline(s) in
the following manner.
To establish baseline date on how the Wagner C575
Meter corrolates a specifi application of concrete
moisture contest by weight.
1. % MC (moisture content) = wet weight minus dry weight divided by dry weight mulitplied by

dried to evaporate all the water.
3. Weigh the sample of dry condrete.
4. Add a volume of water that is equal to 1/4
the weight of the dry concrete sample. By
definition this is 25% MC (moisture content).
Measrue this sample with the C575 to see what
the reading is at 25% MC

surface moisture?
A: Most moisture meters can be affected by standing
water or visible water on the materials you are
measuring. You should always wipe off as much
excess water as possible.
#3 Meter Ruggedness
