Glass Thickness Meter and Low-E Coating Detector

Triple Pane Thickness Measurement

Measure glass, air space and overall IG thickness of triple pane windows all at the single push of a button. The GC3000 works with single and double pane applications as well.

Full Low-E Detection Capabilities:

The Glass-Chek PRO is a fully equipped Low-E coating detector capable of locating a Low E coating on a double pane window from a single side. This is a major advantage while testing multi-story buildings where you only have access to the inside of the window.

Identify Type of Low-E Coating and Determine Silver Layers:

When the Glass-Chek PRO detects a Low-E coating, it displays whether it is hard or soft coat Low-E. When a soft coat is detected, the meter classifies it as single, double, or triple silvered. This enables users to identify types of Low-E coatings in the factory or in the field, and its especially useful for glass replacement applications.

Enhanced Compatibility Means More Applications:

The Glass-Chek PRO has an expanded thickness range of approximately 50mm and is compatible with residential and commercial glass. Its also compatible with new Low-E coatings, suspended film (i.e. Heat Mirror), tinted glass, and displays the total thickness of laminated glass.

Multiple Display Formats : You can set up the Glass-Chek PRO to display measurement results in the format that works best for you. Choose from actual values or rounded to ASTM Standards in fractions (in inches), thousandths of an inch, decimal millimetres and more.

NEW Huge 4-Line Display:

Multiple languages available: The Glass-Chek PRO can be formatted to display in the following languages: English, German, French, Spanish (Latin American), Dutch and Italian. The meter comes pre-formatted in English but can be changed by the user.

Completely Portable:

Powered by a common 9-volt battery, the Glass-Chek PRO goes where you go. With the included protective carrying case, you dont have to worry about the meter getting damaged in the field.


  • Measure single, double and triple pane windows for checking in production, verifying at the job site or testing windows already installed in the field
  • Ensure proper orientation of Low-E coatings during installation, inspection or during the production process
  • Order the correct replacement IG unit by determining glass thickness characteristics and the type of Low-E coating. Save time & money and increase customer satisfaction by reducing incorrect ordering of IG units
  • Measure glass deflection in sealed IG window assemblies
  • Measure thickness on many automotive applications
