When it comes to top brands of multimeter testers, Fluke and its many digital multimeter models always make it to the top of the list, no matter who’s making them. These models include the 87-V, 117, 116 HVAC, and 115 Compact True. The reason behind this is the strong and even LED backlight, true RMS rating, solid build, stand at the back, and also a small clutch bag to store the units, together with the probes.
Another top brand is the Innova, specifically with their 3340 Digital Multimeter. It is capable of the best, most accurate measurements given that it is UL certified. It also has an RPM clamp, together with a temperature probe which works best for engine and automotive works. While it has similar features, together with the clutch bag, this one isn’t necessarily fit for working with electronics.
Despite being an “entry-level” multimeter, Klein Tools still does manage to live up to the several advanced features of other more established brands, such as Fluke and Innova. Its measurement is one of the most extensive around, with 10 Amps and 1000 Volts, as well as a feature for auto-ranging of values. It is also equipped with a backlit screen, and is accurate enough for both electronics use and for use in car engines.
