Supco M500 Insulation Tester/Electronic Megohmmeter with Soft Carrying Case, 0 to 1000 megohms Black

Works as planned. Great for the toolbag and easy on the wallet. Not always the most accurate but its close enough for what I need it for

All perfect

Great tool for the job

Use this all the time. When I run up on old systems I always Meg out the compressor before recommending repairs. Easy to use and lightweight. Very happy with it.

Works well in the hvac profession

Simple and saves time.

Fast and safe, good tool to complement compressor diagnostics and inspection. A tip to the seller, should better pack the package as it could damage the equipment.

I love getting this item. It was quick, easy to pay for and it was delivered on schedule

It is quick and fast. The clips are a little small, and the wires a little short, but still worth the money.

Ive been using these at work and love them. Light weight, simple to use and reliable. This will not get down to the finer details of measuring resistance readings but will tell you where the weak spots are in a circuit. The lower cutoff point on this meters scale is 20 Megaohms, well above levels I have seen circuits operating without tripping overloads or breakers. All of the problem circuits Ive diagnosed with my expensive Fluke megger have shown less than 1 Megaohm from conductor to ground. I still love this meter, though, because it is so light and compact. I also like that I can attach the alligator clips and leave one hand free to wiggle wires in the conduit on intermittent problems while I press the test button with the other. I have thus far not misdiagnosed a motor with this meter but I usually go get my Fluke 1507 if I am in doubt. You will love this megger.
