Features

  • Versatile Digital Clamp Meter: Accurately measures AC/DC Current, AC/DC Voltage, Capacitance, Frequency, Duty Cycle, Resistance, Diode, Continuity and Live Wire Tests. This clamp meter is a really useful tool for solving industrial and household electrical issues.
  • Non-contact Voltage Testing: This Clamp Meter features non-contact voltage testing with sound and light alarms. When the Meter senses a weak AC signal, the green indicator light will come on and the buzzer will emit a slow, audible beep. when the Meter senses a strong AC signal, the red indicator light will come on and the buzzer will emit a brief beep
  • Multifunctional & Easy to read: Support Data Hold, Max/Min, Auto power off after 15 minutes inactivity, low battery indicator and continuity buzzer. The LCD Backlit Screen and Flashlight make it easy to use in a dark working area. ZERO function decreases the data error influenced by the Earths magnetic field, and helps you to obtain a more accurate measurement.
  • Large Jaw Opening: The jaw opening measures current in a conductor without touching or interrupting the circuit. Its slim and compact size makes it easy to operate in narrow spaces.

  • Worth the investment
Style: 2000 Counts AC Current
I need to add remote to an old ceiling fan with lights having a tiny canopy space, and also enter some power estimate data so I can get a much better picture of my energy consumption too. This is the exact equipment I need. There are many fan remote kits but they all have a current limit. The more compact a receiver is, the less current it can handle. The internet yields 0 results to the fan model and all I know is this thing handles at most 3A total, while the receiver’s limit for the motor is 1A max. I used this clamp to clamp around the wall switch load wire so I can see how much peak current it used to start the fan rotation and how much stable current it uses. It’s a half amp fan so that I have a wide variety of remote kits to pick from. This also allow me to estimate energy usage of some lights or even at the panel. Great tool. ... show more

  • I should have bought one sooner
Style: 4000 Counts AC/DC Current
So I didn’t think if it at the time upon purchase. However I just used this thing to track a live wire in the wall, from an outlet I thought was straight up dead. The circuit started working out of no where. I used the clamp feature like a fox & hound Ethernet signal tracer. Where when near the wire, you pickup the solid beep, or two tone sound. I tried doing the same with the one that I have that does the same thing, but intended more for finding which breaker it’s on. I couldn’t use that other tool to follow it through the wall, floor, and outside like I did with this more sensitive multimeter. It does all the other things just as you expect. But that discovery was a perk I didn’t expect. I figured like the other tool old have to have the clamp up against the wire. So cool ... show more

  • Not the most accurate reader, but the price point makes it great for entry level
Style: 4000 Counts AC/DC Current
apprentice electrician work, I'm usually dealing with 12VDC-48VDC or 120VAC-480VAC, nothing too crazy but the work doesn't need to be precise. Usually checking to ensure completely dead components, voltage on devices, continuity, and general current readings just for ballpark load calcs. Overall this works just as well for me, as my Boss's $300+ meter works when we work in the field. Once I get to a higher level in my career I may upgrade, but this will have a special place as my first proper meter, and continues to get used daily. ... show more

  • Surprisingly sturdy with a nice case
Style: 2000 Counts AC Current
I was pleasantly surprised when I received this. It's seems heavy, sturdy, and well made. It comes with a nice case as well. It also has some extra unexpected features like covers that screw off to make the contactors longer or shorter depending on your job. I'll never use all the sophisticated features, but it's definitely an upgrade from my previous one. I used it on a couple quick tests and it worked great. The no-contact feature worked well too. I also like the flashlight and the backlight feature on the readout screen. ... show more

  • Great inexpensive meter!
Style: 2000 Counts AC Current
This meter is a life saver when it comes to an all around deal perspective. I cant afford to go out and buy the top dollar meter or replace the middle ground one every time some idiot runs over it (its me im some idiot), nor do i wish to use those $5 poopiles that cant even test continuity properly. So this thing being as inexpensive as it is, while being durable, having the settings i need, and the tick test feature i didnt even realise was a thing, thats just awesome!!! My main complaint is there is clearly a lack of thought in reguards to design, the flash light points directly into the clamp prongs, blocking most of the beam even if you were to hold them open the whole time you used the light, that and maybe the function buttons having poor labeling/layout. ... show more

  • Versatile Multimeter
Style: 2000 Counts AC Current
I was looking for an inexpensive multimeter for the garage and I can't be happier with this meter. It's so versatile with the clamp ampmeter, non-contact testing capability and normal multimeter functions. It even came with a carrying case! How's that for a sub-$20 meter?

  • Accurate with lots of features
Style: 6000 Counts 1000A AC/DC Current
I bought this inrush clamp meter (Astroai CM600) and a KL**N CL445 inrush clamp meter at about the same time. I immediately tried both meters on a 4 ton heat pump. The astroai consistantly measured 110 amp inrush which is close to the 100Amp LRA on the nameplate. The KL**N would only display OL. Tried many times to measure the same inrush with the KL**N and could not. Measured steady state AC current successfully and both units were within 1/2 amp of each other. The Astroai does DC through the clamp, the KL**N does only AC. All other features were about the same. The Astroai was a little more than 1/2 the price of the KL**N. I returned the KL**N. Very happy with this meter. ... show more
