Buyer’s Guide

With a low current clamp meter, you can measure just about any type of electricity. Even in modern times, it’s common and useful for people who work with electricity all day long!

True RMS feature:

Clamp meters are a standard tool for electricians, but have you ever wondered what the true RMS means? True RMS is a feature that’s on most digital clamp meters. It stands for Root Mean Square and it tells you how much power your circuit carries at any given moment in time. This measurement is more accurate than an average reading because not only is the peak value is taken into consideration but also the time between peaks.

Jaw size:

When looking for a low amp clamp meter, make sure to pay attention to the jaw size. This is the measurement of the opening where you clamp the meter around the wire. The smaller the jaw size, the more versatile the meter will be in measuring smaller wires and in tight spaces. But, keep in mind that smaller jaws may not be able to measure larger wires.

AC/DC measurement:

When you’re looking for a low amp clamp meter, make sure it can measure both AC and DC current. AC current is the type of electricity that comes from your power outlets, while DC current is the type of electricity that comes from batteries. Some meters can only measure one or the other, so if you’re working with both types of electricity, make sure you get a meter that can measure both.


A clear and easy-to-read display is essential when using a low amp clamp meter. Make sure to look for a meter with a backlit display or a large, easy-to-read digital display. This will make it easier to read measurements, even in dimly lit environments.


Different low amp clamp meters will have different functions and features. Some meters may only measure current, while others may measure current, voltage, resistance, and more. Consider what types of measurements you’ll be taking most often and look for a meter that has those functions.


Safety is of the utmost importance when working with electricity. Look for

a meter that is rated for the level of voltage you’ll be working with, and that has safety features such as overload protection and a low battery indicator. Also, look for certifications such as CAT III or CAT IV rating, which indicate that the meter has been tested and approved for use in certain environments.


A low amp clamp meter is an investment, so make sure to look for one that is built to last. Look for a meter with a rugged design and one that is made with high-quality materials. It should also come with a warranty or guarantee for added peace of mind.


Some low amp clamp meters come with accessories such as test leads, carrying cases, or temperature probes. Consider what accessories would be useful for you and look for a meter that comes with them.


Low amp clamp meters can range in price from budget-friendly to quite expensive. Consider your budget and what functions and features are most important to you. Keep in mind that a more expensive meter may have more advanced features and better accuracy, but it may not be necessary for your needs.


  • What is a low amp clamp, and what is it used for?
  • A low amp clamp, also known as a low current clamp, is a type of electrical tool used to measure low levels of electrical current. It is often used in electrical testing and diagnostic applications, such as checking the current draw of a device or circuit.
  • How does a low amp clamp work?
  • Low amp clamps work by using a transformer to isolate the measured current from the rest of the circuit. The transformer allows the clamp to measure the current without interrupting the flow of electricity. The clamp’s jaws are placed around a conductor, and the measured current is displayed on a digital readout or analog meter.
  • What are the benefits of using a low amp clamp?
  • Using a low amp clamp has several benefits, including the ability to accurately measure low levels of current without interrupting the circuit, the ability to measure current in hard-to-reach or hazardous areas, and the ability to measure current in live circuits. Low amp clamps can also help to identify problems in electrical systems, such as short circuits or faulty components.
  • How do I choose the right low amp clamp for my needs?
  • When selecting a low amp clamp, it’s essential to consider the range of current that needs to be measured, the type of conductor being measured, and the intended use of the clamp. It’s also a good idea to consider the durability and accuracy of the clamp, as well as any additional features it may have, such as temperature measurement or data logging capabilities.

Wrap up:

All the clamp meters which are described in this article are highly impressive because of their qualities, features, and performance, which perform measurements accurately and fulfill the safety ratings. All clamp meters are multi-functional, measuring voltage, resistance, diode testing, duty cycle, and frequency, and all have the common feature of low amp measurements.
