There is a "little"failure in this chart... It is written that a light year is 9.5x10^17 sec  :-DD

Hello,

The bodge looking resistor and lifted pin in the PH-meter or conductivity meter is not a bodge !
it's designes so as to avoid current leaks through isolation material. The PCB, IC socket are leaky at the pA level, especially with some contamination

This is why I don't like 2min teardows. These meters seemed simple enough for more details with out it being too much work. But instead it was just "theres some analogy stuff and chips". What was the point? To show a glimpse of a PCB?
