GC3001 Glass Chek Pro Review: Features, Specs, and Who It’s For
The GC3001 Glass Chek Pro is EDTM’s glass thickness measuring tool for shops and inspectors who need real answers about insulated glass without taking a window apart. This review covers what it measures, what changed from the older GC3000, its practical limits, and who should consider it.
Key Takeaways
• The GC3001 measures glass, air space, and overall IG thickness and detects Low-E, including hard or soft coat and silver layers.
• It has an approximately 2-inch range and works on single, double, and triple pane windows.
• One button push tells you the exact replacement IG unit to order.
• If you need to identify laminated glass and measure the laminate layer, compare it with the GC3200 ELITE.

What the GC3001 Does Well
One-push answers for glass replacement
With one button push, the GC3001 tells you the exact replacement IG unit to order. For a replacement shop, that is the main benefit: fewer guesses and fewer incorrect orders.
Low-E detection from one side
The GC3001 can find a Low-E coating on a double-pane window from a single side, useful when you can only reach the inside of the window. Compared with the older GC3000, which could only confirm Low-E on Surface 3 or 4 when the coating was on the far pane, the GC3001 can confirm Surface 3. EDTM notes this does not apply to certain window types.
Low-E type identification
When it detects a coating, the GC3001 displays whether it is hard coat or soft coat, and for soft coat whether it is single, double, or triple silvered. That matters in the field and on the factory floor, because replacing glass with the wrong coating can hurt energy performance and change the window’s appearance.
Wide compatibility
At approximately 2 inches of range, it works with residential and commercial glass, newer Low-E coatings, suspended film such as Heat Mirror, tinted glass, and it displays total thickness of laminated glass.
What Changed From the GC3000
• Screen advance buttons. Arrow keys let you move forward and back through results instead of waiting for screens to run automatically.
• Membrane switch front panel. A smooth front panel replaces the protruding power switch and button guard.
• Menu system. Hold the arrow key to change operating modes, units, languages, and screen advance speed.
• More languages. Swedish and Danish join the existing six.
• Welcome screen reminder. A graphic reminds users to measure at the bottom center of the window and shows the current operating mode.
• Improved quality. A more durable LCD and a higher-precision laser for more accurate readings.
First-Use Setup Checklist
1. Install a fresh 9-volt alkaline battery.
2. Press and hold the arrow key to open the menu.
3. Choose your operating mode, units of measure, language, and screen advance speed.
4. Read the welcome screen, which reminds you to measure at the bottom center of the window and shows the current operating mode.
5. Take a measurement, then use the arrow keys to move through the result screens.

Pros and Cons
|
Strengths |
Limitations |
|
One-push answer for the replacement unit to order |
Total laminated thickness only; no laminate layer breakdown |
|
Low-E type identification, including silver layers |
Surface 3 confirmation does not apply to certain window types |
|
Single-side Low-E detection on double pane |
Best results depend on measuring at the bottom center |
|
Approximately 2-inch range; menu with several languages and unit formats |
Runs on a 9-volt battery, so keep a spare |
Limits to Know Before You Buy
• Laminated glass. The GC3001 shows total laminated thickness. If you need to identify laminated glass and measure the laminate inner layer, EDTM’s newer Glass-Chek ELITE is built for that.
• Surface 3 confirmation. It does not apply to certain window types.
• Technique matters. Take readings at the bottom center of the window for the most repeatable results.

Support and Ownership
EDTM states that its glass testing equipment has been trusted by more than 5,000 companies worldwide over the last 25 years, and that expert service is a phone call away if you have a technical question or if your meter is ever damaged. For product questions, EDTM lists its phone number as (419) 861-1030.
Who the GC3001 Is For
• Glass replacement shops ordering IG units
• Window installers and service technicians working in the field
• Production personnel spot-checking units
• Building inspectors and surveyors documenting existing glass
• New or experienced users, since the menu and welcome-screen reminders support less-trained staff
If your work regularly involves laminated glass, compare it with the GC3200 before deciding.
