Linshang as a laser glass thickness gauge measuring tool suppliers, provides two models of glass thickness gauge can be used to detect the thickness of various single-layer glass, double glazed, triple glazed, multilayer glass, laminated glass, LOW-E glass, and insulating glass, especially suitable for measuring the installed glass. Doors and windows and curtain wall glass thickness. When measuring the thickness, the thickness of the glass and the thickness of the air layer can be displayed at the same time.

I. How to select glass thickness gauge?

To select a cost-effective glass thickness gauge, what users concern most is the functions of the glass thickness gauge including the glass thickness measurement tool application fields and glass thickness measurement range. Here, we list some necessary functions about the glass thickness measuring tools.

  • Uses laser reflection pinciples for glass thickness measurements.

  • Suitable for measuring on Single, Dual, Triple Glazed Units, laminated glass, etc.

  • It is accurate to measure from either side of the installed glass, no need to remove the panel and no exposed edges or opening required.

  • It can also measure the thickness of air space intermediate layers in sealed IG Units.

  • Simple to use and easy to carry – Just one button to press and read the results.

II. How to Measure Glass Thickness?

1. Measure triple glazed using LS201 digital glass thickness meter

LS201 is a digital glass thickness meter, press the "measure" button to measure the thickness of the instrument and the glass thickness will be directly displayed on the screen. We take the measurement of triple glazed glass as an example.

glass thickness gauge

  • The thickness of glass 1, glass 2 and glass 3 are 5.86mm, 5.93mm and 5.89mm respectively.

  • The thickness of air space 1 and air space 2 are 12.72mm and 12.63mm.

2. Measure double glazed using LS200 glass thickness gauge 

LS200 is a glass thickness gauge that needs to be read by a scale. The glass thickness is calculated based on the upper scale data, and the thickness of the air layer is calculated based on the lower scale data. We take the measurement of double glazed glass as an example.

glass thickness meter

  • The glass thickness of the first layer = A-B = 30-25 = 5mm

  • The air space thickness = B-C =12-2 = 10mm 

  • The glass thickness of the second layer = C-D = 5-0 = 5mmI

III. Glass that can be Measured with a Glass Thickness Gauge

The glass thickness gauge is used for the accurate thickness measurement of flat glass. Some of glass types that can be measured is as below: 

Triple glazed (IG units) Double glazed (IG units) Single pane float glass
