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

Excellent meter, great price too!

I needed a good battery tester, having experienced that the usual cheap ones were not very reliable. I decided that I may as well invest in a multimeter that could test batteries. I'm very pleased with this - exceptional quality for the price (YouTube reviews attest to build quality) - and it will test 1.5V / 9V batteries 'under load' to give an accurate remaining voltage reading. You have to use the supplied leads to 'touch' the battery +/-contacts so perhaps not as convenient as many specific battery testers, but this multimeter does have a built-in stand which means you have both hands free.

works as it should hopefully will last

This is the second multimeter I have purchased. I wanted to test an earthing sheet and the one purchased from Halfords wouldn’t test low enough. This one did the job as much more accurate and a much sturdier feeling device. It has since proved itself again with vehicle fuse checking saving me garage costs. Would thoroughly recommend.

Klein Tools MM325 Multimeter, Digital Manual-Ranging 600V AC/DC Voltage Tester: Love my new Klein multi-meter, very accurate readings, nice clear screen, 'normal' batteries, and the leads are good quality. I bought an off-brand hard fabric case for it to keep the leads in good nick. Lovely multi-meter, and just as good as the bigger more-expensive "F" brand units.

Good quality.

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-built Accurate readings Clear backlit display Great value for the price Cons: Doesn’t measure milliamps or microamps (not a dealbreaker for most) Slightly bulky for small tool pouches Verdict: Highly recommended for electricians, HVAC techs, or DIYers who want reliability and ease of use without going for high-end professional meters.
