High quality capacitance and resistance meters

I bought this megger for a specific project. It worked great. And for the price I will have it on hand for future projects. I used it to test my underfloor heating cables prior to installation. This is a very specialized test. Other tools cost over $300. A plus

Pros
  • Easy to use
Cons
  • Crumpled

Inexpensive for occasional use

This is a decent gauge and worth having on hand for occasional use. I have never seen it fully open and have had to rely on light to indicate continuity. I used it to diagnose a motor that wasn't considered grounded with my 9 volt meter and it helped. I'm glad I have it, but it's not a tool for regular use.

Pros
  • New
Cons
  • Cons

Good deal for capacitance and resistance meters

Works. I removed some pretty decent transformers, lots of copper, and still tested them closely against much more expensive big brands. I tested both 5kV and 500V. One downside I noticed is that the screen doesn't light up if you turn the dial too fast. Weird, but be careful when you turn it on and it works every time.

Pros
  • Delivery was very quick
Cons
  • Cable is shorter than other picks

Good price for an insulation tester.

This tool is not widely used but should be in every technician's toolbox for testing insulation resistance. In this case it was originally used to identify a faulty wire leading to a well pump motor. A multimeter can sometimes detect this error on an ohmic scale, but will not have enough voltage to actually test insulation resistance. This is a critical test, especially when powered by a variable speed motor.

Pros
  • Certified
Cons
  • Hard to tell
