  • Fluke alternative?
Was on the fence of spending the big bucks on a fluke for shop life, but heard great things about Klien from my foremans. The build quality is great and doesn't feel like dropping it will break it. Very sturdy unit. Functions amazing with the auto detect option, but still giving you the choice to manually select range. Says it measures high enough voltage for EV but I've yet to test EVs at work. Display quality is amazing and very clear. Size of the unit is average. Speed of reading could be improved but its not slow enough where you're loosing money on doing electrical diag. You're doing electrical diag already lol ... show more

  • Great features and price
High quality, plenty of features, easy to operate if you have electrical knowledge otherwise it’s useless. Clear audible sounds, easy to read display w/back lit features. Fuse protected, fuses are replaceable and available at Amazon as well as accessories for this particular meter.

  • Accurate, durable meter with great features for field work
I’ve been using the Klein MM720 for troubleshooting electrical issues and general testing, and it has turned out to be a really solid multimeter. The True RMS auto-ranging capability makes it easy to get accurate readings without constantly adjusting ranges, which is especially helpful when working with fluctuating AC loads.  The meter feels rugged and well built. It has a good grip and seems designed for job-site use. The reverse-contrast display with an optical sensor is surprisingly useful because it automatically adjusts visibility depending on lighting conditions, making it easy to read in bright areas or darker panels.  Another feature I appreciate is the Low Impedance (LoZ) mode, which helps eliminate ghost voltage readings when troubleshooting wiring. That’s a big advantage when working on residential or light industrial circuits.  Things I like most: • True RMS auto-ranging for accurate readings • Measures voltage up to 1000V, current up to 10A, plus resistance, capacitance, frequency, and temperature  • Low impedance (LoZ) mode helps identify ghost voltage • Bright, easy-to-read display that adjusts to lighting • Durable build rated to survive a 6.6-ft drop  • Includes test leads, thermocouple, pouch, and batteries One small note: the meter is a little larger than compact hobby meters, but the larger display and durability make it worth it for real electrical work. Overall, this is a reliable and feature-packed multimeter that works well for electricians, technicians, or anyone needing a dependable diagnostic tool. ... show more

  • Great meter at a great price
Digital multimeters run the gamut from über cheap (in every sense of the word) to oh-dear-god-who-would-pay-so-much-for-a-meter??? This meter is a great meter for casual users. Accurate and with a wide range of features, this meter costs a fraction of the price of meters you might find in a professional lab. (I work in a professional lab, and not once have I ever wished I had my "work meter" in my garage workbench. This Klein meter is a fine meter, indeed.) The standard test lead connectors means all aftermarket test leads work with this meter, too. Alligator clips, mini-grabbers, spring-loaded probes all work with this meter. For the price, this meter would be hard to beat. ... show more
