Joe Clanin,

Here is the eBay auction number for the meters that I like.

eBay item number: 173095200763

These are from China, so be prepared to wait a month or more!

I bought a 2 inch, metal cutting hole saw to mount them.

Attached is a picture of one in a "portable box" as opposed to a Lowe's box with tabs for wall mounting.

It is connected to my portable 80 volt, 60 mil loop supply.

The meter box is eBay item number: 402624692225, It ships from New Jersey.

A 100 mil meter reads just over half scale for 60 mils, which is a comfortable place to be.

I have couple 200 mil meters in my junk meter box, but meters may not be very accurate near the bottom of the scale. So I only use them in a pinch to show the presence of loop current or not.
