MM325 Multimeter, Digital Manual-Ranging 600V AC/DC Voltage Tester, Tests Batteries, Current, Resistance, Diodes, and Continuity

I’ve been using the Klein Tools MM325 Multimeter for a while now, and I’m really impressed with how well it performs for both DIY and professional use. The build quality is solid—typical of Klein Tools—and it feels durable enough to handle daily use in a toolbox or on a job site.The display is clear and easy to read, even in lower light. The auto-ranging feature works accurately and saves a lot of time when switching between different measurements. It handles voltage, continuity, and resistance testing reliably, and the leads are sturdy with good flexibility.One of my favorite features is the backlight and data hold function—it’s a small thing, but it makes a big difference when working in tight or dark spaces. The battery life has been great so far, and the protective rubber case gives it a rugged feel that inspires confidence.If you need a dependable, mid-range multimeter without spending a fortune, the MM325 is a fantastic choice. Klein’s attention to detail really shows here.Pros:Sturdy and well-builtAccurate readingsClear backlit displayGreat value for the priceCons:Doesn’t measure milliamps or microamps (not a dealbreaker for most)Slightly bulky for small tool pouchesVerdict:Highly recommended for electricians, HVAC techs, or DIYers who want reliability and ease of use without going for high-end professional meters.

I've used Klein tools for at least 45 years and I have never been disappointed in the quality and reliability of tools by Klein. This is a reasonably good meter for the price.

Arrived as described. This completes my Klein electrical test set. Recommend this vendor to purchase from.

I love this meter. I use it everyday in my work as a technician. It hasn't failed me yet. It's easy to use and seems to be accurate. It replaced my $300 fluke which bit the dust after so many years of excellent service. This Klein works just as good. It is a little bit smaller than my Fluke was and therefore fits better into my tool pouch pocket. The case is very durable and the screen lights up well. It is a very good value for the money.

I've been a fan of Klein Tools for awhile now; mostly the hand tools used for wiring and networking. When my 30 year-old multimeter died, I decided to get a simple Klein meter as a replacement. In terms of functions, it does everything that I need it to do. This is a manual meter but as someone that might reach for a multimeter half a dozen times a year, that's plenty adequate. Plus my old meter was also manual. I think this meter will serve me fine for years to come. I'm deducting one star because at this price point, I think a basic meter of this build quality should include a carrying case. The other reason why it gets a ding is that the continuity checking can be slightly fickle. I can't get the tone to consistently sound when checking continuity without fidgeting the leads a bit. It's not just the continuity tone, but other readings as well. I'm finding that I need to move the leads around to get a solid reading for most applications. Not a big deal and maybe that's how meters are at the lower price points. It's just something to be aware if you're looking for something with good sensitivity.

very useful, practical and functional

Bought for around the house use. Great meter. Very accurate and easy to use. Would recommend.

Great little meter for basic use. Wish I got one with auto range, but oh well. If you're going to rely on a meter for daily use, you should probably buy a Fluke.
