LS200 Glass Thickness Meter User Manual V4 Measuring Glass and Air Space Individual Panes
The LS200 Glass Thickness Meter is mainly used on measuring glass and air space in
insulated glass (IG), it also can measure individual panes of glass and the thickness of a
glass bottle etc, special for those situations where common ruler can not easily do it.
This Thickness Meter utilizes the light reflection principle to achieve its function. When
laser is set against the surface of glass, Laser reflection beams off the surfaces of glass
appear on the graduated scale of
the meter. The readings are taken
from a single side of glass and the
user can get the thicknesses of
glass, the air space at the same
time. High quality red laser gives the
reliable measuring result.
I. Parameters
1. Weigh: 250g
2. Resolution: ± 0.5mm
3. Dimensions: 160mm*55mm*25mm（L*W*H）
4.Power Supply： CR2032 battery 3V
5. Range: Glass Thickness Scale 70mm, Air Space Scale 34mm
II. Operation
Prior to every reading, verify the meter is resting flatly against the glass surface. Do not
tilt the meter or place any items under the meter when taking readings. Tilting the meter in
any way will adversely affect the accuracy of the readings.
The meter can easily measure glass thickness, air space, overall IG thickness,
individual panes of glass in a laminated assembly, bullet resistant and triple pane
assemblies. The meter also has been successfully tested for measuring thickness of
mirrors and other transparent materials.
For single pane glass two reflection beams will occur, double IG units four beams will
occur, triple IG units, six beams will show.
III. Measure thickness of IG units
Put the meter flatly against the insulated glass surface (two layers), press the Power
Switch and hold on, 4 red reflection beams will be seen on the scale. The reflection beams
“C” and “D” is the thickness of the first layer glass on “GLASS THICKNESS” scale, “D” will
align with the “zero point “, and so the thickness of first layer glass is the number of “C” on
the “GLASS THICKNESS scale. A =30mm,B=25mm,C=5mm,D=0mm. The thickness of
first layer glass is C – D=5mm,the thickness of bottom layer is A – B =5mm.
Distance between B and C on the “AIR SPACE THICKNESS” scale is the air space. B
=12mm,C=2.4mm, The thickness of the air space is B – C = 9.6mm .
IV. Notes
1. It is imperative that the measured glass surfaces is kept clean and free of any
debris, otherwise causing incorrect readings
2. Keep the scale clean; do not wipe the meter with alcohol, or other organic
dissolvent.
3. Replace the batteries. Remove the four screws
located on the bottom surface of the meter.
Replace the CR2032 batteries and refasten the
cover. Be sure to install the batteries correctly
(polarity +/-).
4. Keep the meter far away from high
temperature or high humidity.
5.This product emits a laser beam from the back
side. DO NOT point the laser at anyone’s eyes.
ALWAYS check the other side of the window
being tested to ensure that no one will be
looking directly into the laser.
