Earlier this week I had posted a question asking how to determine which surface that the Low E coating was applied to. I got a few responses. I then called the glass guy and he siad just use an Ohm Meter and check the dge of the glass. Since the Low E is metalic you will get a reading. So I did not have to buy a $200 meter!!

How does the meter work if the coating doesn't go to the edge of the glass?
"It is what it is."
Mike, I was wondering the same thing.
What's that guys name that was here a few months ago who was apparently a window glass expert?
Riversong, but he has moved on. I think he took his posts down.
Not Riversong.The glass guy is Oberion or something like that..

A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.

Thats right, he just thought he was the expert!
As Frammer52 still wanders the internet looking for something he can claim expert status....
Dude, you don't have to respond to every thread ever posted.... really you don't.... no I'm being serious here... let a thread you know absolutely nothing about pass without responding.... Try it just once, it'll be tough but just try... then the next thread you know nothing about and let pass will be easier.... then the next and next.....
And next thing you know the urge to respond to every thead you haven't a clue on will pass.....
Consider this internet intervention.... you need it bad. Real bad.
Hi, it's nice to meet you?
what did I do, pee in your cereal?
Dude. out of 34 treads that show up on the first page I have responded to 10, would you like to take that back?
Out of the next 40, I have responded to 6, shall I go back further?

Seriously dude... you don't have to respond to every thread...
Take a break.
PLEASE
Well should I go back further?
16 out of 74, is that a lot?
Since LowE coatings are electrically conductive, it is possible to check for a coating simply by completing a (really) simple circuit using the coating as one leg of the circuit.
You wouldn't need a $200 meter, a (really) simple light/battery/wire circuit (HS science class) tester would work fine. However, unless the coating was on an exposed surface, the meter wouldn't work anyway, as was posted eariler.
The simpliest way to check for LowE coating is to hold an open flame near the surface of the glass when it is dark outside (technically it doesn't have to be dark, it is just easier to see).
You will see either three or four reflections of the flame in the glass. If you have a LowE coating, one of those reflections will be a different color than the others. That is the reflection of the coating.
You can determine the coating location by seeing where the odd flame-color is in relation to the other two or three flame-colors. The closest flame reflection is the glass surface that you can physically touch and the furthest flame reflection from you is the outer side of the lite away from you. The "middle" one or two reflections are the glass surface(s) inside the IG unit.
Make sense?

Had a number of thermopanes delivered that were assembled inside out, low-e coating on the outside. The low-e coating is a thin film of silver which tarnishes very quickly when exposed to air. You can accelerate the process by wiping the glass with some vinegar, trust me, if the low-e is on the outside you'll be able to tell ..
Actually, depending on the coating, there could be one, two, or three layers of silver and several layers of other metallic oxides used for both protecting the silver and enhancing visible transmittance.
But, you are right on that you can easily tell when the coating is outside the IG unit and also that vinegar will certainly make that readily apparent!
Hopefully, you caught the error before the units were installed?
