GLASS-CHEK+
Glass and Air Space Thickness Meters
MODEL# GC2001
GENERAL DESCRIPTION:
The GLASS-CHEK+ measures the thick-
ness of both lites of glass, as well as the
airspace of an insulating glass window as-
sembly. All thickness measurements can be
obtained from a single side. Simply press
the GLASS-CHEK+ meter against a single
lite of glass, or a double pane window,
push the power button and hold it until the
measurements are digitally displayed. The
thickness of each lite of glass, the air space,
and the overall thickness of the IG unit will
simultaneously appear on the 2-line LCD
display. On a separate results screen the
meter will also indicate the presence and
location of any Low-E coatings on the first
pane of glass.
The GLASS-CHEK+ contains a single pane
Low-E coating detector. The single lite Low-
E detector will test the nearest lite of glass
in an IG unit. To fully analyze an IG unit re-
garding Low-E coatings, the window should
be tested on both sides to confirm the pres-
ence or absence of the Low-E coating. If
you only have access to one side of the
window, we recommend upgrading to our
Glass-Chek PRO (Model # GC3000).
The user may choose to have the thick-
ness results displayed in one or two of
the following options: fractions of an inch,
thousandths of an inch, or millimeters. The
results screen will flash between the differ-
ent thickness options selected by the user.

GLASS THICKNESS & AIR SPACE
MEASUREMENT
Simply press the GLASS-CHEK+ meter
against the single or dual lite window as-
sembly and push the button. Continue to
hold the button and the measurement re-
sults will appear within two to five seconds
depending on the application. Tinted glass
applications will typically take longer to mea-
sure, while standard clear windows usually
result in the fastest measurement. Hold the
meter steady during the measurement. The
results will be displayed on the screen and
will continually flash back and forth between
thickness data and the Low-E location for
the first pane of glass. For best accuracy
please see the "FOUR OPTIMAL TEST
LOCATIONS FOR MOST ACCURATE
RESULTS" section below. Windows often
deflect inward or outward due to varying
barometric pressures. The window will hold
closest to its original designed specification
along the edges and at the corners where
the spacer bars hold the glass fixed. The
thickness sensing area of the GLASS-
CHEK+ meter is located along the bottom
edge of the meter. Therefore the four test-
ing locations shown in Figure 1 below will
yield the best results. We recommend tak-
ing multiple readings to verify your re-
sults. Whenever possible, ensure that the
glass sample under test is clean and that
the exit location (aperture) of the laser is
clear of lint, dirt or other contaminants. The
laser aperture is on the back side of the
GLASS-CHEK+ enclosure.
WE STRONGLY RECOMMEND ONLY US-
ING COMPRESSED AIR TO CLEAN THE
LASER APERTURE. However, if there are
fingerprints or other smudge marks on
the laser aperture window that cannot be
removed in any other way, a lint-free cloth
can be used to wipe off the smudges.
The GC2001 instrument can test the thick-
ness of installed windows from either indoors
or outdoors. In most all applications it does
not matter what is behind the window, as
long as there is nothing touching the far side
surface of the window. For testing windows
in the factory or warehouse, make sure you
are only testing one window at a time. If
testing a stack of IG's, you must move the
unit you are testing away from the stack
so the additional panes of glass are not
added to the measurement viewing area. If
testing in a lab, be sure to move the glass
off the table surface before testing.
FOUR OPTIMAL TEST LOCATIONS
FOR MOST ACCURATE RESULTS
Ÿ Hold the meter steady AND FLAT against
the glass during measurement.
Ÿ The meter should be centered on one of
the four edges of the window with the bot-
tom edge of the meter placed parallel to
the edge of the window (please see the
image to the left). This will minimize the
effect of a concave window. As you move
away from the edge of a window, many
windows will bow inward (concave). Be-
cause the sensor runs parallel to the bot-
tom edge of the meter, it is important to
place the bottom edge of the meter along
one of the four edge locations as shown.
GLASS CHEK+ LOW-E DETECTOR
OPERATION
The GLASS-CHEK+ will automatically test
each measured window for the presence
and location of Low-E coatings on the first
pane of glass. The meter will differentiate
if the coating is on Surface 1 or Surface 2. It
will also indicate if the first pane of glass is
clear glass, meaning there are no Low-E
coatings present on the glass. Remember
that Low-E coatings are typically placed on
surface 2 or 3 of a window. If you are not
sure which side of the window was intended
to have the Low-E coating, you may want
to test both sides to ensure you have fully
tested for the coating. If testing both sides
of the window is not possible, you should
consider our Glass-Chek PRO (Model# GC
3000) that will test both sides of a double
pane window from a single side for Low-E
coatings.

DISPLAY OPTIONS
The display of the GLASS-CHEK+ meter is
pre-programmed at the factory to offer six
different display formats for the results
screen. The user can choose to have the
thickness measurements displayed in:
Fractions of an inch ... with 1/32" resolution
1/8 1 /2 1/8 IN
TOTAL IG: 3/4 IN
Decimal inches ... with 0.001" resolution
0.125 0.500 0.125 IN
TOTAL IG: 0.750 IN
Millimeters ... with 0.1 mm resolution
3.0 12.5 3.0 MM
TOTAL IG: 18.5 MM
The user may choose to have any one of
these units of measure displayed, or a com-
bination of two of them. If a single unit of
measure is selected, the results screen will
alternate back and forth between the thick-
ness results and the Low-E test results.
If the user selects two units of measure,
the results screen will alternate between
the first unit of measure for thickness, the
Low-E results screen and then the second
unit of measure selected.
To change the display format, take a mea-
surement and continue to hold the button
while the results are displayed multiple
times. After approximately 40 seconds, the
screen will prompt you to enter set-up mode.

APPLICATIONS
WILL TEST ...
The GC2001 instrument is calibrated and
designed for testing flat glass applications.
It will test both single pane and double pane
windows. The glass can be clear glass or
coated with Low-E coatings, self clean coat-
ings or other specialty coatings as long as
the glass/coating is transparent. The GC
2001 will also measure tinted glass as long
as it has a visible light transmission value
of approximately 35% or above.
WON'T TEST ...
The GC2001 is not capable of measuring
triple pane windows or glass that is coated
with reflective (mirror-like) coatings. The
GLASS-CHEK+ is also not capable of test-
ing suspended film applications such as
Heat Mirror. Laminated glass with Low-E
coatings positioned against the laminate
can also NOT be measured.
these applications we recommend our
Glass-Chek PRO (Model# GC3000).
CLEAR
GLASS
LAMINATED GLASS:
The GC2001 will test regular laminated
glass assemblies. It will measure the
all thickness
of the laminated assembly, as
long as there is no Low-E coating placed
against the laminate inner-layer. The lami-
nate assembly can be a single piece or com-
bined into an insulating unit. The GC2001
will NOT measure the PVB inner-layer or
the individual pieces of glass making up the
laminated glass, it will only measure the
overall thickness of the laminated glass.
TRIPLE PANE & SUSPENDED FILM
The GC2001 will not attempt to measure
triple pane windows. The user must pur-
chase the Glass-Chek PRO (#GC3000) for
this application.
HIGH/LOW RESOLUTION ... SPEED OF
MEASUREMENTS
The GC2001 has been equipped with a High
Resolution and Low Resolution Mode. The
meter is shipped in Low Resolution Mode as
this allows for the quickest measurements
to be taken. The quicker measurements
come at the expense of a little accuracy.
If extreme accuracy is not important, then
the low resolution mode is perfect for get-
ting the quickest test results possible.
If you are testing glass for an application that
requires higher accuracy, you can switch the
meter into High Resolution Mode. This will
improve the meters accuracy as stated in
the specification section of this manual. The
improved accuracy will cause the meter to
take measurements more slowly. To change
the resolution/speed of the meter, take a
