Features

  • Through-hole design: Easy Wiring; Measure positive or negative current; No current direction limitation
  • Electrically isolated from high voltage power source which eliminates risk to delicate monitoring equipment and also minimizes safety concerns
  • Display Voltage or (+ -)Current; Voltage Range: 5V-120V; Current range: 0-400A
  • Compatible with large wire; Diameter of the hole through sensor is 3/4 inch(19 mm)
  • Loop through sensor multiple times to strengthen signal. For example, if your current signal is only 0.2 Amps, you could loop the wire through the sensor 10 times and the signal would by 10X stronger and would appear as 2.0 Amps

  • Works great
Works great, measuring current
Reviewed in the United States on December 24, 2024 by Andy

  • Good meter for the value, as long as you are aware of a few limitations.
This is a good DC amp meter for applications that require basic accuracy, with little chance for moisture intrusion, and depending on the application, may need additional things to make it useful. My application was intended for an upgrade to a shop style, rolling, car/truck battery charger. I am very pleased with the upgrade and outcome, but there are a few things you need to be aware of before using this meter. This is an "inductive style" DC amp meter, not to be confused with the more traditional, shunt style DC amp meter. Meters using this technology need a way to zero the meter before each use. For example, the Fluke 80i-1010 AC/DC clamp meter (used to measure the accuracy of this panel meter) uses a thumbwheel to zero the meter before taking measurements. This panel meter uses a small, normally open switch, mounted to the back of the PCB, that you press and hold three seconds to re-zero the meter before use. This switch also serves as a mode switch, which allows the user to change the display between, constant volts, constant amps, or alternating volts and amps about every 10 seconds. For my application, I wanted instant viewing of volts and amps, so I purchased two of the same units (400 amp devices). For my application, one meter would be set to display DC VOLTS only, and the second meter, DC AMPS only. I did not want one meter to display one reading, then alternate to the other reading, which this meter will do if you so desire. My old analog meters were removed and I fabricated new mounting plates to agree with the original meter holes and accept the new panel meters. Meters were installed, the "charging" and "charge complete" LEDs were mounted, and I was able to test the upgraded battery charger. Issue...as this is a panel mounted device, to access the re-zero button, you need access to the BACK of the unit, but if its mounted in a panel, this can be impossible. To mimic the pressing of this button while the meter is mounted in the panel required the soldering on of a small, normally open push button switch (seen in the photo). This may or may not be easy for people because the components on the PCB are surface mount, meaning they are very small. The switch where you need so solder on the wires is incredibly small. CAREFULLY, solder on the wires to the side of the switch, or as I did in my case, carefully bent header pins. From here, you can easily add the pushbutton switch and mount it to the front of the case. As to the meters accuracy, I have attached a photo of the meter in use. Comparison is to a Fluke 117 / Fluke 80i-1010 clamp meter, set to DC amps...plenty accurate enough for a battery charger, and, much more accurate than the meters they replace (whole reason for doing this upgrade to the battery charger...so I can see the low amp delivery to smaller batteries or batteries that are in maintenance charge mode. Note that in using this meter for the past week, the typical variation or "drift" due to temperature works out to around 2 amps indicated, over a period of about an hour (between a temperature of 50F to about 75F). If you can live with a couple of amps inaccuracy, you dont need to worry about soldering on a switch to this device. You can absolutely solder to the switch, but you must have a very fine tip soldering iron to do so, and be very comfortable working around surface mount electronic components. If the engineering department or people that developed this meter are reading this review, please put provisions on the PCB for revision 2 for headers to attach an auxiliary mounted reset switch. Not many people are going to be equipped to handle soldering to a surface mount switch to make this meter useful. You have a handy device that is very useable and plenty accurate enough for most applications, but is not user friendly have to modify to make it useable in the field. I am happy with the meter, but do be aware of the limitations. If you are equipped with a a fine tipped soldering iron and have good eyes and a steady hand, you can have a lot of fun with this upgrade. ... show more

  • Dandy meter!
Great DC amp meter for the price. Easy to install and use. Very helpful piece added to my radio stand.

  • Good unit, good value. Longevity?
Simple to install. Seems accurate. Doesn't look very robust and since my installation is outside it may not stand up to corrosion very well.

  • Lens came scratched up
The media could not be loaded. Works good. 4/5 stars because it came with the lens all scratched up (see photo). I used this guage to add an amp/volt guage to a 225 amp automotive charger. It alternates from volts to amps. Easy install, just connect the positive and negative to the pos and neg leads inside the charger, unhook the positive lead inside and slide the hall sensor over the cable and reassemble. Now I can tell if the battery is taking a charge and I get an instant battery voltage reading as soon as I connect the charger clamps to the battery ... show more

  • Perfect for high current car audio needs
The voltage accuracy is uncanny. The precision power supply I used to test these were down to the hundredth decimal place. As soon as I ramped the voltage past .05, the LCD rounded up immediately and went up a tenth volt. All 5 of them did the exact same thing. I wasn’t expecting this amount of accuracy. I haven’t tested the current side as I haven’t installed my secondary batteries yet but I needed something to measure over 200amps per battery and this fits the bill. I had to install a momentary switch to zero out the meter and change viewing options but overall great unit for great price. ... show more

  • Good meters.
Works better than hoped. Great for my van conversion. Should have gotten 4 of these as i bought 2 volts only not realizing these toggle v then a. Wish cal could be ganged and also had a separate switch port. Soldered on spdt momentary and ok now.
