How we ranked these
This list covers current clamp meters from Fluke, Klein Tools and Kaiweets with a maker page we could read and a maker photo we could use. Each pick was scored out of 100 with the same rubric from the maker’s own product page, read on 2026-11-02: clamp current (20 points), True-RMS (10), safety rating (15), numeric current accuracy (10), jaw opening (5), inrush (5), LoZ (5), non-contact voltage (5), Bluetooth or wireless logging (5), published price (10) and warranty (10). A figure the page does not state scores zero. Scores: Fluke 375 FC eighty-four, Kaiweets HT206D seventy-seven, Fluke 376 FC seventy-four, Klein Tools CL900 sixty-five, Klein Tools CL810 sixty-five, Klein Tools CL710 sixty, Fluke 325 fifty-nine, Fluke 323 fifty-two, Fluke 902 FC fifty and Klein Tools CL390 forty-two. The CL900 and CL810 tie and the CL900 ranks higher on its larger current range. Best value is the lowest published price among the picks scoring sixty or more. Every figure is vendor-stated, not lab-measured. Klein Tools publishes no prices or warranty terms on its product pages, which lowers its scores under a rubric that gives zero for an unstated figure, and Klein’s accuracy line reads See Instructions. Battery life, display, build quality and measured accuracy are not scored. We left out the Milwaukee 2237-20, Extech EX655 and Amprobe AMP-330 because the product photos available from those makers were below 900 pixels wide, the Klein Tools CL800 because Klein’s page marks it discontinued, and the Hioki CM4141 and Southwire 21550T because we could not read a current maker page for them, and the Uni-T clamp meter because its page said out of stock. No company paid for or adjusted a position. Prices are those on each maker’s page on the read date, include sale prices where shown, and change often. Photos come from each maker’s own site: the Fluke 902 FC, Klein Tools CL900, CL810 and CL710 images are in-use shots, and the others are studio product shots. Facts are taken from each maker's own published information; check the official site before you buy.
