I have one of thees, I think it is a good tool to help test what you have. Size, pacific gravity, ping test, weight, Diamagnetic, V. Paramagnetic, V. Ferromagnetic, ultrasonic testing, looks, resistivity & etc.
I use the same meter to test side wall thicknesses on fuel oil storage tanks and water storage tanks, never gave your application a thought, thanks for this eye opening video..well done!
I'm looking at the list of metals at 2:38. What the hell is 'glod'? Though I make fun of the unit's manual, I'm buying a tester right now because the price has dropped to $70. I wonder if I can set it for exotic metals like tungsten or titanium or magnesium because I have samples for all of those. I even have some rhenium slugs and I can't wait to test them.
Thickness of course can be duplicated by alloying metals to get the identical weight per size. I would think resonance of materials would be harder to nail. The "ring" to it ....need decices that check resonance/thickness (dimension)/resistance/and OFCOURSE weight. I would think it virtually impossible to nail all four on one counterfeit coin or bar
Anguinus Vir the machine shoots a sound wave through the coin from one side to the other and back. if any material other than the one being tested for is encountered the sound wave will have a different travel time and an erroneous thickness will display on the machine.
He's not kidding. Each element in the periodic table has a different sound wave propagation speed. This is a property of materials. wiki for gold lists the speed of sound in the material: en.wikipedia.org/wiki/Gold

I think your device is called the "stone Digital Ultrasonic Thickness Meter Tester Gauge Metal Tester 1.2-220mm GM100"

jeffw1267 you can set it to any speed number you want

thanks excellent review
does this work to detect with tungsten inserts/cores?
Checking for "specific gravity" seems to be rarely mentioned.
Rob where did you get your ultrasonic devise from?
Got mine second hand off Kijiji.
How can we bet you sir
There is a new invention. Tripod.
There is no manufacturer's name anywhere or model number. It just says made in China. I bought mine second hand. Sorry.
There is no manufacturer'
Gold 3240, Tin 3230... so anyone can scam you with tin gold plated coin.... you will get same result
Wrong
@@Rob_Adventures but you will get SAME thickness. But in addition if you make magnet test then you will catch fake gold
Yes best to both tests
@@DedoTi different density so can't have same dimension with same weight.
This proved nothing. A silver plated coin with correct thickness would read the same as solid silver coin. This is stupid.
Anguinus Vir the machine shoots a sound wave through the coin from one side to the other and back. if any material other than the one being tested for is encountered the sound wave will have a different travel time and an erroneous thickness will display on the machine.
robmajorfitness - Prove it!
Anguinus Vir I bought this shit off amazon and barely makes the difference between metals

@@anguinusvir6698 you know how silly you look dude? "prove it!" XD smh. science bruh...
