The Best Clamp Meters in 2024
1. Fluke 323 True-RMS Clamp Meter
|Current Range||up to 400 A (AC)|
|Voltage Range||up to 600 V (AC and DC)|
|Resistance Range||up to 4 kΩ|
|Safety Ratings||CAT IV (300V) / CAT III (600V)|
One of the greatest clamp meters available is the Fluke 323 True RMS. Both home and business electricians can benefit from its unique design. What sets this device apart from others is its ergonomic construction for use in the roughest industrial settings. It weighs only 265 grams and measures 207 by 75 by 43 millimeters (mm), yet is durable and dependable (H x W x D).
Accuracy is 2% +/- 5 digits (45 Hz to 65 Hz) for AC currents up to 400A, and 2.5% +/- 5 digits for DC currents of the same range (65Hz to 400 Hz). It is important to remember that the Fluke 323 True RMS clamp meter does not read direct current. To the nearest 1.5% (+/- 5 digits) for AC measurements and 1.0% (+/- 5 digits) for DC measurements, you may expect values up to 600V for both types of voltage. Your resistance readings up to 4 k will be accurate to within +/- 1%.
Under 70, the clamp meter can offer continuity by emitting a beeping sound. There are flaws with this clamp meter. The extended plugs at the ends of the test leads are a unique feature. When put on a flat surface, they become more troublesome. Furthermore, the multimeter comes with a 2-year guarantee and a safety grade of CAT III (600V) and CAT IV (300V). You’ll get the test leads, the case, and the instructions with your order.
What sold us on Fluke devices was the company’s dedication to providing excellent support to its customers. The goal of their website was to create a simpler shopping experience. In addition to the user handbook, they include a calibration manual, reference guide, safety sheet equipment, and a clamp selection guide, all of which are excellent resources. The Fluke 323 True RMS multimeter is a great option if you’re looking for a high-quality clamp meter.
2. Extech 380947 True RMS 400A AC/DC Mini Clamp on Meter
|Current Range||up to 400 A (DC and AC)|
|Resistance Range||up to 400 Hz|
|Safety Ratings||CAT III (300V), CE and UL tested|
When looking for the best clamp meter, the Extech 380947 True RMS 400A AC/DC Mini Clamp on Meter is a fantastic selection. If you need to operate or measure extremely small currents, this is the best option. The high resolution measurements (1mA for AC and 10mA for DC) are the real show stopper with this clamp meter. All the important measurements parameters and signals may be seen on the huge 4000 count LCD display. This LCD screen also has a 40-segment analog bar graph for further functionality. That makes it feel like the numerous measurement displays are happening in real time.
The 380947 model’s clamp meter features an adjustable jaw that may open to a depth of 0.9 inches for convenient use (23mm). It’s important to note that this clamp meter is technically rather advanced. Capable of delivering AC currents with a +/- (1.5% accuracy) throughout a range of 4A/40A/100A/400A. It can measure DC currents of up to 400A with a precision of +/-(1.0%). It has a frequency range of 0 to 10 kHz with a resolution of 0 to 0.01 Hz and an accuracy of 0 to 0.5%.
The Extech clamp meter that I have does not measure alternating current or direct current. The other versions, 380942 and 380941, can monitor voltage, though. Further, it is only useful while troubleshooting, and a few users have complained that the meter readings are quite sluggish owing to the higher accuracy settings. Despite this, it is still a fantastic nimble and flexible instrument, measuring 7 by 1.8 by 1.3 inches (178 by 45 by 32 millimeters), and weighing 225 grams (8oz). The Extech 380947 True RMS 400A AC/DC Mini Clamp on Meter is an excellent choice if you need a meter that can measure low currents for diagnostic or troubleshooting purposes.
3. Klein Tools CL800 Digital Clamp Meter

Choosing the Right Clamp Meter: A Buyer’s Guide
Electrical current may be measured with a clamp meter, which is a type of electrical instrument. Compared to the conventional way of monitoring current flow, these gadgets significantly increase safety (which is cutting a live wire and measuring the current flow by inserting a test lead on the circuit).
As a result of the risks associated with this procedure, a clamp meter was developed. To measure current, a clamp meter applies the current transformer concept. The magnetic flux is detected and measured by the clamp in the clamp meter, which then displays the current measurement on a screen.
Clamp meters may be divided into two basic varieties:
An Alternating Current Clamp Meter
Particularly, these instruments are used to gauge alternating currents.
A DC Clamp Meter
Tools that measure both direct current and alternating current. For precise current readings, a DC clamp meter often makes use of a Hall Effect sensor.
Clamp Meters: What You Need to Know Before Buying
Assurance of Security
When shopping for a clamp meter, safety features should be your first priority. By inspecting the device’s casing and hardware, it’s easy to see that this is the case. The higher the device’s total voltage, current, and resistance ratings, the less risk it poses. In addition, a plethora of regulatory certifications, issued to only the safest equipment, serves as a loud and clear indicator of a product’s reliability.
Clamp openings are the actual holders you’d use to grab onto the conductor, therefore their dimensions are what the term “clamp size” refers to. Likewise, the widths of these apertures might be anything from 17 millimeters to 45 millimeters. Clamps may be found in a range of sizes as well. On the sizing spectrum, they are adjustable.
In order to accommodate the conductor, they are expandable and may be shrunk down to a more manageable size. In addition, clamp meters typically have non-contact voltage detectors that first check the wire’s conductivity by wrapping the clamp around it. It is possible to test a circuit’s conductivity in this way without touching any of the components.
Limit of Maximum Resistance
How much of an electrical current a clamp meter is able to halt is indicated by its resistance, which is expressed in Ohms. The resistance to current flow via the conductor can be gauged in this way.
There are clamp meters that measure resistance up to 10 kilo-ohms, but most only go up to 4 kilo-ohms at most. High resistance, perhaps up to 20 kilo-ohms, may be necessary when working with heavier conduction instruments. If you just plan on using the gadget in one place, a little resistance should suffice.
LCD Display with Backlighting
Since most electrical work is done after hours, when it is dark, having a screen with a backlight is a terrific addition. Because of this, gauging conduction will be a breeze. Since not all clamp meters come standard with backlit displays, you’ll want to make sure you choose one that does.
Clamp meters measure the crest factor, or the peak of the current wave, using a clamp. You may calculate it by comparing the peak current value to the Root Mean Square Value (RMS Value). This information is crucial for determining the severity of circuit overloads. Keep an on-screen metric that allows for a direct readout of this figure in mind.
Support for Mobile Devices
Most new digital DC clamp meters connect to mobile devices wirelessly through Bluetooth or near IR technology. You can examine the measures remotely after installing a little app, without having to be in close proximity to the measuring equipment or screen.
This is not only a foolproof technique but also an effective one since the user can fine-tune the machine with the aid of their smartphone. Email, online document collaboration, and cloud storage are all examples.
Although not all clamp meters have a warranty period, reputable brands of clamp meters often have a 1-year manufacturer’s guarantee beginning on the date of purchase. In addition, there are a select few manufacturers that will back their products with a three-year guarantee.
Maximum Allowable Current in Amperes
It is a measure of the clamp meter’s durability that indicates how much of the rated current the device can handle. A device with a rating of 1000 Amps may be considered industrial strength, whereas those with ratings of 300 Amps or 400 Amps are more typical of the kind of tools found in homes and workshops. The option you pick would be determined by your requirements.
Supplemental Parts and Pieces
Since you will likely be working in a remote location, away from your typical toolbox, a clamp meter with extra accessories like a tiny LED light, a nice dust-free cover, or a few alligator clips or points will be of great aid.
