Glass Thickness Gauge | Professional Glass Checking and Measuring Tools & Solutions

I.  What is the use of glass thickness gauge?

Glass thickness meter is mainly used to measure the thickness of glass and the thickness of the air layer in the middle. Linshang handheld glass thickness gauges using the principle of laser reflection, the glass thickness and the thickness of the air layer can be measured by placing it on one side of the glass. It is especially suitable for places where it is difficult to measure with tools such as vernier calipers, such as measuring installed door and window glass, curtain wall glass, etc.

Glass thickness measurement is essential for ensuring safety, quality control, and compliance across industries. In architecture and automotive manufacturing, precise glass thickness guarantees structural integrity, impact resistance, and adherence to safety standards. It plays a crucial role in manufacturing precision, maintaining consistency in products like windows, displays, and optical lenses, reducing defects, and improving efficiency. For multi-layer and coated glass, accurate measurement ensures proper lamination and coating thickness, critical for construction, aerospace, and security applications. Additionally, in energy-efficient glazing, correct glass and air gap thickness directly impact insulation performance, reducing heat loss and improving sustainability.

II. How to select a suitable 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. Hereby, we list some necessary functions about the glass thickness measuring tools. To choose the best glass thickness gauge, we have some tips for you to refer to.

• Uses laser reflection pinciples for glass thickness measurements.

• Suitable for measuring single layer glass, double glazing, triple glazing, laminated glass, insulated 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. An instrument that grandma would use.

III. How to Measure Glass Thickness?

Linshang Laser Glass Thickness Gauge is a durable and reliable instrument designed for measuring both glass thickness and air gap in insulated glass units (IGUs). By utilizing laser reflections from the glass surfaces, the gauge projects these reflections onto a graduated scale, enabling quick and precise thickness determination. It allows users to measure the glass and the air space within a sealed IG unit from a single side, eliminating the need for additional tools. This user-friendly device simplifies the process, making it an essential tool for professionals.

1. Measure triple glazing using LS201 digital glass thickness meter

LS201 is a digital glass thickness meter, press the "Measure" button to measure the thickness of the sample. The thickness of the glass and air space will be directly displayed on the screen. We take the measurement of triple glazing as an example.

• 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 glazing using LS200 laser glass thickness gauge

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

• 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

If you need real-time digital display, high accuracy, and data recording capabilities, go for a LS201 Digital Laser Glass Thickness Gauge. If you only need basic laser-based glass thickness measurement, a standard LS200 Laser Glass Thickness Gauge is sufficient.

VII. FAQs about glass thickness measurement

1.  What factors affect the measurement accuracy?

● Surface cleanliness - dust, coating or fingerprints will interfere with the reading.

● Lighting environment - too strong external light may cause the instrument to fail to recognize the glass. Try to avoid testing the back of the instrument facing the sun.

● Glass composition - laminated glass and coated glass may require advanced instruments to obtain accurate readings.

2.  Can I Measure Glass Thickness Without Removing It?

Yes! Laser glass thickness gauges and some ultrasonic models allow for non-destructive measurement from one side of the glass, making them ideal for installed windows, automotive windshields, and safety glass.

3. How Accurate Are Glass Thickness Gauges?

LS201 digital glass thickness tester has ±0.1mm accuracy, and the LS200 has ±0.5mm accuracy.
