Here is a picture of the Tek 422 with the front cover. The shell, including the cover is made of aluminum with the thickness of a coin! The whole Tek 422 exudes quality. No mucking about!
Here is a pic of my favorite VOM: the Simpson 269. This meter used to cost more than 2x the much more popular Simpson 260. The area of the meter face is 2x that of the Simpson 260. The meter movement has 100,000 ohm/volt vs the 260's 20,000 ohm/volt. At the 8 volt range, the impedance is already 800,000 ohm. Its impedance is close enough to the 1M ohm of a oscilloscope with a 1x probe! All this from a passive VOM!
There are 3 Simpson 269 series. The best and rarest is series 3. It comes with Taut Band meter movement that eliminates needle movement friction. No need to tap on the meter face to unstick the needle to get an repeatable reading. The other 2 series doesn't have taut band. However, series 3 is very rare; I hardly ever see it on ebay.
Anyway, the Simpson 260 is hugely more popular and the Simpson company probably sold 100 to 1 the 260 vs the 269. You can get a rough estimate by counting how many 260s are for sale on ebay vs the 269. However, the Simpson 269 easily trounce the Simpson 260 in almost every way. The Simpson 260 and Triplett 630 fanboys are missing out!
