C575 Features:
Your Wagner Electronics hand-held concrete meter
was designed using electromagnetic wave technology, to
make fast assessment of concrete slab dying patterns
easy and inexpensive. Large areas can be surveyed
quickly and easily. Wagner Electronics 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 specic area and
depth penetration. However, readings from concrete
moisture meters should NEVER be used to determine
if a concrete slab is dry enough to install a oor
covering. 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 at, clean, metal surface at
least 1/8 inch (3.2 mm) thick, such as a car or truck
hood or a le cabinet. Press hand meter sensor rmly
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.
Note that the meter sensor is covered with a self-
adhesive replaceable Teon abrasion pad. Replace
Teon pad when worn through to sensor, or when
edges or corners loosen. Do not use the meter with
debris under a loosened edge or corner.
Replacement Teon pads are available from your
distributor or by calling Wagner Electronics
Customer Service [phone].

also recommended that you take a number of tests
close to one another and use the highest reading.
Moisture readings in concrete may be affected by5.
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.
Interpreting the Reading:
Readings are relative and are useful for comparing
moisture levels in various locations of a concrete
slab and to determine where to place additional tests
using ASTM F2170. Place additional tests in locations
where the C575 reads the highest. It is strongly
advised that ASTM F2170 relative humidity testing
methods be used to determine if the oor is ready for
the oor covering. Do not use the C575 to determine
if the concrete slab is ready for a oor covering.
This meter is designed to provide information as to
where the wettest parts of a slab are so further testing
can be done in those areas. The meter does not measure
vapor pressure (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
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:
The surface of the concrete should be brushed1.
clean of loose debris and dust.
Turn on the meter and verify the2.
“Low Battery” light does not
illuminate.
Place the sensor of the meter on the3.
area of the concrete to be tested.
Press down rmly, making sure the
sensor rests at against the concrete.
On a rough surface take a number of readings4.
close to one another. If the readings vary, use the
highest reading. On a normal smooth surface it is

readings is affected by a number of variables so the
readings must be considered relative on a slab by
slab basis. Use the meter to determine the best loca-
tions for placement of the manufacturer’s suggested
test. Further testing methods such as relative humidity
testing should always be used to determine if the
concrete is ready for the oor covering installation.
Questions & Answers:
#1 Wagner Electronics Technology
Q: I’m nervous about buying a new technology.
How long has Wagner Electronics been designing
and manufacturing this type of moisture meter?
A: Since 1966, Wagner Electronics has been providing
quality moisture measurement equipment.
#2 Surface Moisture
Q: Is my Wagner Electronics moisture meter
affected by surface moisture?
