    Great little pocket meter for on the go

    This little pocket multimeter has a large display with large numbers which make it easily readable. Its small enough to carry in your pocket or backpack. Easy, small, and portable. Can’t complain.

    ✔ Yes, I recommend this product.

  2. JDragon62

    Great for quick jobs

    Have had a version of this meter for the last 15 years and they have always been reliable and easy to use. The compact size make it easy to grab along with a screwdriver and pliers for the quick jobs that don’t require a full toolkit.

    ✔ Yes, I recommend this product.

  3. Chuck42

    excellent product

    easy to use, works effectively – and pocket size. very happy with it

    ✔ Yes, I recommend this product.

  4. stefanomazza

    Easy and efficient

    A pocket multimeter that allows the main tests, with a very good accuracy if compared with professional instruments.
    Battery consumption is minimal. Highly recommended.

    ✔ Yes, I recommend this product.

  5. captive

    Easy to Use and Effective

    A very compact multimeter with autoranging. Makes for simple, easy use, particularly the ability to move the selector dial with a thumb or finger one handed.

    ✔ Yes, I recommend this product.

  6. flounder

    convenient to carry, hard to use

    Nice. Fits in my shirt pocket. But when I want to measure something, I have to use my left hand to hold the black probe, my right hand to hold the red probe, and my prehensile tail to flip the switch. Oh, wait, I don’t have one of those. Some nice little hands-free accessory wire clips would have been nice. try holding the leads in series with an LED to show current and you quickly get the picture.

  7. Yorks

    Excellent meter…..

    Small & compact, accurate (I compared to a Fluke 117), good price, no complaints.

    Great for quick measurements.

    ✔ Yes, I recommend this product.

  8. Motorwiz2002

    Small but packs a lot.

    Autorange feature is nice in this price range. Cap and diode test. Only missing amp test.

    ✔ Yes, I recommend this product.

  9. Amprobe

    We apologize for this rare product quality issue. We strive for the upmost quality in all our products. All Amprobe products are covered by a one year warranty. Please call 1-877-AMPROBE for service assistance.

    Rotary dial DOA

    This could be a great little multimeter, but the rotary dial didn’t work properly – the registration notches where it comes to rest were apparently mis-aligned. To get the expected functionality, I had to hold the dial still in a slightly off-center position, by maybe 10 degrees CCW or so.

    I’ve had issues previously with the (linear slide) mode dial being unreliable on another brand of pocket multimeter. I am still looking for one that will work reliably.

    ✘ No, I do not recommend this product

  11. truckconducter

    a good meter for the diy

    i am a diyer and use my meter to check most all my work. it meets most of my needs .

    ✔ Yes, I recommend this product.

  12. scfd503

    Great tool

    Really like the vesatility and size of this meter. Great to work with.

    ✔ Yes, I recommend this product.

  13. dwlsn7778

    A MUST HAVE FOR EVERY HANDYMAN’S TOOL BOX , NOTHING ELSE WILL DO!!!

    I was given one of the new Amprobe PM51A pocket digital multimeter by an electricain friend/neighbor who felt that I could really benefit from an upgrade from the bargain bin model that I have had and used for sometime now.The tool is a god send and I will not let anyone borrow it out of my sight so that it does’nt disappear some how.The PM51 is loaded with some may great features that it would take to long to list them all with out forgetting something,you just have to pick one up and you won’tput it back without purchasing at least one or two for yourself I guarantee it.

    ✔ Yes, I recommend this product.

  14. Doug47

    Good low cost multimeter

    This multimeter is easy to use and accomplished the job each time it was used. It is reasonably priced for the handyman without complicated electrical issues.

    ✔ Yes, I recommend this product.
