    • Love this meter
Style: Tester
I work in HVACR and needed a megometer quick. Recommended this one from a training class and decided to try it out. For the price this meter is perfect in my opinion. It has an amazing, big, bright screen with good size numbers. It feels sturdy and is a good size. Comes with good accessories as well. Will definitely recommend this in the future to other techs as a good mid to top tier megometer. ... show more

Great, reasonably priced meter. 1kv megger, true RMS, resistivity, continuity, 1kv tester all in one package. A bit on the heavy side, but has a nice rear angled support.

Great meter, has helped me track down shorts that don't show on a regular multimeter a few times now, and also just to give some peice of mind if you really want to make sure you don't have any.

    • Pro‑grade meter that adds on‑board megohm testing
Style: Tester
The Klein ET600 feels rugged right out of the box—rubberized housing, drop‑safe, and a clear backlit display. As a everyday TRMS multimeter it covers the basics (voltage, continuity, capacitance) with quick, auto‑ranging response, but the real win is the built‑in insulation tester: selectable 125 V, 250 V, 500 V, and 1000 V outputs let you verify motor windings or cable runs without hauling a separate megger. Test‑lead shields and an audible alarm add safety, and the hold/max features simplify logging. Only downside is the 4000‑count resolution, which is fine for field work but less granular than lab‑grade meters. For electricians who need a single, tough tool that handles both standard measurements and insulation resistance, it’s excellent value. I use this unit to mainly test SR trace heat cables, and I have taught many others how to perform these tests with this unit. It's ease of use has been very helpful for this mission. Thanks Klein! ... show more

Big Fluke guy but didn’t want to spend money on a Fluke Megger as I usually just ohm motors so I got the Klein to use the Megger when needed. I’ve used it a few times and it works as it should.
