Insulating glass thickness gauge is a professional device for measuring glass thickness based on the principle of optical reflection. The instrument can complete the test on one side of the glass, in addition to measuring the thickness of the glass layer, it can also measure the thickness of the intermediate air layer. Ordinary insulating glass, laminated insulating glass, three-glass two-chamber glass can be tested.

At present, the measuring range of this product's insulating glass thickness gauge is 70 mm for glass thickness and 45 mm for air interlayer thickness. Many customers may not know this parameter very well, and still cannot confirm whether the measurement range meets the test requirements when purchasing the instrument. How thick can the insulating glass thickness gauge measure the insulating glass?

To answer the above question, we need to consider the number of layers of glass and air. The refractive index of air is 1. The refractive index of glass is 1.5. The laser reflection principle used by the instrument ultimately requires the refractive index to calculate the thickness of the glass and air layers. So, if you want to confirm your instrument before buying it, you can use the following formula to convert.

1. If you measure single or multi-layer glass without interlayer, the glass thickness that can be measured with a glass thickness gauge is 70 mm.

2. If measuring the insulating glass with two waves and one cavity, the measurable insulating glass can meet the following requirements: the thickness of two layers of glass + the sum of the thickness of the air layer*1.5 .

3. If measuring three-glass two-chamber insulating glass, the measurable insulating glass can meet the following requirements: the total thickness of three layers of glass + the total thickness of two layers of air* 1.5.

If you are not sure whether your sample is outside the scope of the instrument when choosing an insulating glass thickness gauge, you can simply use the above method to judge. If you still have questions, please feel free to contact us.
