You can go to Bed Bath and Beyond for this honey available at $44.95 ~ in this configuration the capacity is a mere 320 pounds ~ no porkers here eh.
Obviously this will NOT stand up to a huge 13,000 KG item, but the only claim of a picture of a bathroom scale in the Rossi videos is where one was used to weigh a module ~ at 80kg ~ for which this scale would be satisfactory.
At the moment this particular scale is calibrated at .2 pound increments but you reprogram the chip and toss in a more robust bit of coding for counting you could probably run the precision all the way out as far as the chip's adding machine is capable ~ (thinking of chips in terms of their devices is a good way to understand what the force measurement device is doing).
You'd need a stronger containing frame to weigh 13,000 kg, but why would you need that much capacity when you are only weighing 80 kg.

Which brings up the difference between precision and accuracy. It may be reading in 0.2 lb increments, but it could be off by several pounds.
I recall reading that Rossi "calibrated" his scale by having someone who claimed to know their weight stand on the device.
That's nice and all, but not particularly reassuring that they were getting accuracy in the gram range, which is what Rossi was claiming.
I don't see that measurement as being particularly significant. Whether he add 50 grams or 100 grams doesn't really make any difference as far as I can see.
What's much more important is that Rossi has consistently refused to do a "null" test, where he didn't inject any hydrogen to demonstrate that his device behaves any differently when hydrogen is absent.
No doubt Rossi's fans will suggest that he may have done such testing in secret, but "Rossi said" is not evidence.
Apparently you missed the 1MW test data acceptance sheet where he weighed the H2 cannisters at over 13,000 kg.
BTW, I am STILL waiting for you to present the specs of a strain gauge that will measure one part in a billion ...
