The Merlin Lazer gauge measures glass thickness and air gaps in any combination on clear single or multi-glazed units quickly, easily and from one side only.
1 Glass thickness
This scale gives a one-touch measurement for glass thickness.
2 Air gap

2
This scale will measure the air gap in any clear double or triple glazed unit. Used in conjunction with the Glass Thickness scale,
it will enable the overall thickness of any double or triple glazed unit to be measured quickly and simply.

With the help of the raised logo button, the scale can be moved to the left or right to set the zero line to the required position.
5 Laser on/off button
Press to activate laser. When the button is released the laser is turned off automatically.
How to use the Merlin Lazer
Whatever type of clear glass is being measured, ensure that the
Merlin Lazer is placed flat against the glass face at eye level.
When measuring double or triple glazed units, ensure that the right hand,
raised edge butts up against tthe bottom right or top right corner of the unit in order to obtain a true reading for the air gap (Diagram 2) - as air gap thickness may deviate towards the centre of the unit.
