MM450 Slim Digital Multimeter, Reverse Contrast Display with Lead Alert, Auto-Ranging TRMS, 600V AC/DC Voltage, Current, Resistance, Temp, Frequency, Continuity

Small and compact. It takes AAA batteries and the fuses are easily accesible unlike the fluke ones. I wish I didn't waste my tome with Fluke all these years. The only negative, if you can call it that, if that it always defaults to mixed AC/DC mode. I never use those modes since can give false or inaccurate readings. So, set the dial and press the button one for AC, twice to work in DC. Luckily the auto shutoff keeps the last setting.

I've been a fan of Klein Tools for years, so considering a Klein multimeter wasn't difficult at all. I've used mostly Fluke multimeters in my 40+ year carreer as a technician. They are considered the best of the best. With that accuracy, repeatability, and quality, you pay dearly! So I was looking for a second lower-cost meter. I was also looking for a reverse backlit display--white numerals on a black background. I'd looked at Milwaukee, but they do not include a diode check function. I chose the MM450 for it's features and price point. While I have not compared accuracy to other meters, published specs are similar to other more expensive meters. There is one minor issue in my review, and that is the white-on-black display needs to be viewed pretty much head-on for best quality. Depending on the tilt angle, there are positions where the display is very faded, almost to disappear. That might be an issue if you measuring in tight quarters or not able to look straight on otherwise. It comes with test and temperature probes, and fabric case. An optional rare-earth magnetic hanging strap is available. Besides voltage and current, it also measures resistance, capacitance and frequency, along with a peak hold function, making it an ideal meter for most service techs. One other minor detail...when in Auto scale mode, it can take up to 5 seconds for the reading to finally resolve. If you are troubleshooting something point to point and in a hurry, this may be an annoyance. However, if you turn off the Auto-scale mode, the readings display quite a bit faster. Given the display issue (and that might not be a problem for everyone) I'd give it a 4.5, if that were possible. But it's certainly better than a 4, so a 5 it is!

This works really well

Likes: I like the overall size of the meter, thin and not too small, not too large. Has bright orange soft rubber edges, good for grip and impact resistance. The dial could be slightly larger but is also cover in rubber which makes it easy to turn. The screen is bright and has adjustable brightness. It reads everything I need it to, the included ambient temp probe is a nice bonus. Easy access to fuses in the battery compartment. Only dislike is the plastic screen is very easily scratched and marked up, in fact, out of the box the screen had fine scratches, as rugged as this thing seems they really dropped the ball on the screen toughness. I cut a screen protector and put it on, it doesn’t look the greatest but if it helps protect the screen... If they fixed that, it would easily get a 5/5 star rating.

Great quality not too expensive

This meter is awesome. It is very accurate, even measures temperature. Reasonably good leads too. Not a highly accurate bench meter, but this is great for the hobbyist, and even pro's who don't need extreme accuracy.

I purchased this meter primarily because of the size. It will easily fit in a shirt pocket. I was impressed with all the features that Klein packed into this meter. The oversized display is easy to read although I did note like a previous reviewer that it can be somewhat difficult to see from an angle. I like the side entry test lead jacks. The jacks even light up depending on which function is selected, which may be helpful for less experienced technicians. It has a milliamp function which makes it useful for instrumentation applications. The microamp function works for burner flame signal troubleshooting. The frequency and capacitance and temperature functions are useful for HVAC applications. This meter has just as many features as a Fluke meter costing 4 times as much! It has a ruggedized shell that should protect the meter from daily use and abuse. Overall I am extremely impressed with this thing. Time will tell how it stands up to industrial and home use

Replacing my old multimeter I really notice the white on black LCD, it's so much easier to read than my old meter. It is thin and the probes come out the side of the body. Rubber grip is good. I appreciate the zipper pouch. It does start beeping at you before it auto powers off which is a little annoying, I myself don't need a warning it's shutting down. I thought the probe tips were too small but it looks like the sleeves come off when I need that. Overall I would buy it again.

Excelente todo bien

I'm an avionics systems technician, I've used a lot of multimeters over the years, this one is the best bang for the buck, by far, it has all the features any common worker will need, it's easy to read and hold, I like having the lead ports on the side. Only thing I noticed when I first started using it was the dial is a little too low profile, can be a little tricky to grasp it.

Works great. No issues. Bright adjustable display. Perfect for most hobbyists and home owners. Leads are long and flexible. Temp sensor works well. Nice case too.

El tamaño es perfecto cumplieron sus funciones muy práctico

Buen equipo, solo que la pantalla no tiene buena visibilidad en exterior, y con luz directa del sol no se ve.
