8 reviews for Amprobe AM-520 HVAC Multimeter

  1. Yambo59

    Good quality and value for the money, some improvements needed

    Ive had the AM520for a few months now and I have mixed feelings. Its a nicely built meter with a good overall quality feel , nice range switch and good looking display, but like so many meters the back light shuts off way too soon – there should be an option in the software to leave it on until manually shut off like some cheaper meters I have. Another issue is the continuity is not near loud or fast enough, also its painfully slow at reading capacitors, its seem to take much longer than most meters and I do discharge the caps first. I like the meter for the most part but feel it should have been better in these areas – for its price point it misses the mark and I dont see why from a company like Amprobe. We went to the moon 50 years ago the technology for these improvements is cheap and it seems to me a multimeter from a company like Amprobe in this price range should not have these flaws in this day and age, especially when some cheaper ones dont.

    ✔ Yes, I recommend this product.

    Happy with the product and results

    I have used this meter since obtaining it in an HVAC class I took. I use it often in a variety of environments. I am very pleased with the meter.

    ✔ Yes, I recommend this product.

    SOLID

    Very solid electrical multi meter, tackles projects with ease, has all features one could possibly need or want.

    ✔ Yes, I recommend this product.

  4. Patrick413

    Nice features, nice price

    I needed something with more features and reliability than the 20 year old hand-me-down multimeter I was using. I primarily use it for HVAC related work (I am not a licensed professional) and automotive hobby work. The back lit display and flashlight have been handy. I’m pretty happy with it. I bought mine on Amazon.

    ✔ Yes, I recommend this product.

    Perfect HVAC Multimeter for the Professional and Student Technician

    AMPROBE AM-520 HVAC METER
    This HVAC multimeter is now my first choice for a troubleshooting meter. I have been using several types of meters, for my HVAC troubleshooting calls, and now I’ve returned to the Amprobe brand. I have worked in the HVAC / Electrical trade for almost 30 years, as a field technician, and using electrical meters is required in my daily job duties. I am a HVAC / Electrical Service Instructor, at the Union, so buying and using digital multimeters is a very important part of my career and job.

    Pros:
    The price is excellent, the combined functions of this meter are superior to other manufacturers on the market.
    The built in strap bracket on the top of the meter makes it easy to hang with the included Velcro strapping.
    The selection dial is easy to read with clear selection points.
    Display light is clear white and lights up the entire display.
    I found the display easy to understand with large numbers to read in tight locations.
    The LED work light, on the top of the multimeter, is great when you are trying to see into a dark HVAC unit or ceiling.
    I love the capacitance checking capability and the ability to check temperatures with one multimeter.
    The micro-amp setting allows you to test flame sensors for heating troubleshooting calls.
    The non-contact voltage detection is a great feature, and helps you troubleshoot with one meter.

    Cons:
    The non-contact voltage detector does not measure low voltage control voltages below 90V-AC.
    The piercing tips on the test leads don’t pierce the wiring insulation.
    I found the hold button is a little awkward to use on the front of the meter.
    The display light only stays on for 25 seconds, this time a little short for most troubleshooting.
    I would like to have had a Type K thermocouple plug on the front of the meter and not the, large plug, Type K thermocouple adaptor.

    ✔ Yes, I recommend this product.
