About 9 months ago, I started a thread covering (mostly) Triplett 310 mini VOMs that I collect. I have have found only a small amount of info about these neat little meters on the web* and had the hope that posters might fill in some time-line blanks, and perhaps have info on other variations, such as the model that has a temperature probe. Here is a link to my original thread:

* since the model is still in production, most "hits" are sites selling these meters,
not historical info.
