Best For Measuring DC: Fluke Clamp Meter

Buy on Amazon

The fluke clamp meter is capable of outshining several other products featured in this list in overall features for the price point. The RMS AC / Dc clamp meter includes a coated instruction card, safety information sheet, soft carrying case, tl75 test leads, magnetic hanging strap and five aa alkaline batteries. It allows for easy illumination and identification of wires. The large, easy to read backlight display automatically sets the correct measurement range so you do not need to change the switch positions while taking a measurement.

The clamp is big enough to get around (at least) a 3/0 feed wire but small enough for tight spaces. It comes with a heavy fabric carrier, not a hard protective case. There is a retainer system on the back and it goes around a few times and then snaps into the top. This meter is perfect for this application.
