Klein ET600 Megohmmeter: My Hands-On Review
I’ve been running the Klein ET600 through its paces for six months now, and it’s become my go-to for insulation testing on compressor motors and control circuits. What sets this apart from cheaper combo units is that the megohmmeter function actually works consistently-I’m talking reliable readings at 1000V on aged motor windings, not the flaky numbers you get from budget models. The auto-ranging TRMS multimeter side handles everyday troubleshooting without switching tools, which saves time on service calls. Build quality feels solid; it’s survived a few drops from condenser units already. My only gripe is the test lead storage-there isn’t any-but that’s minor. At this price point, you’re getting legitimate insulation testing capability without dropping cash on a dedicated megger. For HVAC work, it hits the sweet spot.
