Current Meter - What is it? How does it work?
A current meter , also known as an ammeter, is used to measure the intensity of electric current. To understand its operating principle, you must first know its construction. It consists of a coil of wire coils (around which the tested current passes), a needle, and a display that shows the measurement result. The current flowing through the coil causes a magnetic field to be created in it, which affects the magnet placed inside the meter. This causes the indicating needle to rotate. The higher the intensity, the more the needle rotates. Current meters are commonly used in many areas, especially in electronics, electrical engineering, industry, and scientific research. They allow you to control the intensity of current in electrical circuits, which affects both the optimal use of its resources and the safety of using electronic devices.
Analog current meter - what are its characteristics?
What kind of current meter 
we choose depends on many factors, among which the most important are the accuracy of measurement and the measurement range. No less important are helpful additional functions. The budget that we can allocate for this purchase is also crucial. There are three types of meters available: analog, digital and jaw. Let's start with the traditional, least complicated - analog current meter. Equipped with a pointer showing the current value. Quite cheap and easy to use. Particularly useful for measuring direct current (DC), but quite unreliable in the case of alternating current (AC) measurements. In this case, you need more advanced equipment - a digital meter.
Digital current meter - more modern and more precise
These devices are definitely more reliable than analogue models. They provide accurate and legible measurement values thanks to the LCD or LED display. They also have more different functions, such as resistance or voltage measurement. They work just as reliably in the case of direct and alternating current. Although they cost more than analogue meters, they guarantee much better quality and comfort of work.
Or maybe a clamp current meter - what makes it stand out?
This type of meter is especially useful 
for measuring alternating current. They are easy to recognize by their characteristic jaw. Its shape is not accidental, because thanks to the fact that it opens and closes, we are able to measure current without having to break the circuit. This is an extremely convenient device to use, because it allows measurements in various, even more difficult to access, places. Used especially often in electrical installations and repairs of electronic devices.
Which current meter to choose? Here are our suggestions!
Considering the types of current meters presented above, it is easy to conclude that it is best to invest in clamp meters, especially since they are digital devices and therefore comfortable to use. Which models are particularly worth recommending?
- Digital current clamp meter CMP-200 with calibration certificate from
LCD display (31 digits, max 1999) and white light display backlight. This is a specialist device designed for precise measurements, including small values of alternating current. - Digital clamp meter for alternating current CMP-400 of extremely high quality and precision. The main advantage of the presented device is the ability to perform measurements in the range of 0 to 400, thanks to which it can be used for various tasks in the fields of electricity and automation.
- The FLUKE 325 current clamp meter is designed for professionals who install and maintain electrical systems. It provides measurement accuracy, so measurement results are always reliable.
- The Sonel CMP-401 digital current meter enables precise measurement of both direct and alternating current. Like previous models, the device has a calibration certificate and a cat.III safety class with a maximum voltage of 600V. It is worth noting that the meter is equipped with a clamp opening of 30 mm, thanks to which use even with larger wires and cables is not problematic.
- The Sonel CMP-200F AC fork current meter is an innovative solution from the clamp meter family. It combines the best of both worlds - simplicity, measurement speed and versatility.
By choosing one of these solutions, we can be sure of accurate, undisturbed measurements, which is extremely important in the case of electricity.
