An instrument known as a multimeter is capable of measuring a wide range of electrical properties, including voltage, current, resistance, frequency, capacitance, temperature, and more.
Anyone who works with electricity or electronics needs to have it. But not all multimeters are created equal. The characteristics and functionalities of the various types and models of multimeters vary.
Different multimeters have varying degrees of accuracy and dependability. Different multimeters are better suited to different settings and purposes. Different multimeters offer different levels of convenience and usability.
How can you pick the multimeter that would suit your needs the best? How can you evaluate various multimeters to determine their benefits and drawbacks? How do you tell which multimeter will save you money and provide the most value?
We’ll aid you in finding the answers to these queries in this article. We will contrast four industrial testing-specific multimeters from the website me-ae.com. Since they can all measure the genuine root mean square (RMS) value of an alternating current (AC) or voltage, they are all genuine RMS multimeters.
When measuring AC signals that are not pure sine waves, such as those generated by motors, variable frequency drives, and other devices, the RMS value is crucial. These signals can be precisely measured and read with a True RMS multimeter.

Let’s get going.
Check out these four models from the website mme-ae.com if you’re seeking for a high-quality, precise multimeter for industrial testing. They are all True RMS multimeters that can gauge a range of electrical characteristics, including temperature, capacitance, frequency, resistance, voltage, and more. We will contrast their advantages and characteristics in this post to assist you in selecting the one that best suits your requirements.
A True RMS Multimeter:
An alternating current (AC) or voltage’s true root mean square (RMS) value can be determined with a True RMS multimeter. The corresponding direct current (DC) value that would result in the same heating effect in a resistor is the RMS value. When measuring AC signals that are not pure sine waves, such as those generated by motors, variable frequency drives, and other devices, the RMS value is crucial. These signals can be precisely measured and read with a True RMS multimeter.
What characteristics do these multimeters all share?
These four multimeters are suited for industrial testing since they share some characteristics. As follows:
VFD mode: This function enables precise and reliable measurement of variable frequency drives. Controlling the speed and torque of electric motors is done with the help of variable frequency drives. They are frequently utilized in industrial settings, including those involving pumps, fans, conveyors, and other devices.
However, they have the potential to generate noisy signals and non-sinusoidal waveforms, which can impair the precision of standard multimeters. These aberrations are filtered out by the VFD mode, which provides accurate readings.
The multimeters’ waterproof design enables you to use them in damp or humid conditions without worrying about damage. They can endure immersion in water up to 1 m deep for 30 minutes because they are waterproof according to IP67 specifications.
Use these multimeters in challenging or severe conditions without worrying about damage thanks to the drop test feature. They have passed drop tests up to 2 or 3 meters, meaning they can withstand falls from those heights without breaking.
These multimeters have an LCD display that makes it simple and obvious to see the readings. They have sizable LCD panels with adjustable contrast and backlight. To aid in data analysis, they also include bar graphs and min/max/average functions.
What distinguishes these multimeters from others?
These four multimeters each offer a few special features that may be suitable for your particular requirements. As follows:
EXTECH EX540:
With a range similar to Bluetooth (10m/33 ft), this multimeter provides wireless access to your laptop or PC via a USB receiver. This enables you to remotely monitor and record the readings, then download them for examination later.
Additionally, you can record up to 9,999 measurements using the datalogging feature and review them on your computer or LCD screen.
The multimeter EXTECH EX530 contains a peak hold feature that can record transient pulses for up to 1 millisecond. Electrical circuits can experience transient pulses, which are abrupt fluctuations in voltage or current.
They may be brought on by power surges, switching devices, lightning strikes, and other factors. They may result in false readings on traditional multimeters or may harm delicate equipment. These pulses are recorded by the peak hold function, which then shows the maximum value of each pulse on the LCD.
The LoZ mode on the FLIR DM92 multimeter minimizes ghost voltage readings that could affect your measurements. Ghost voltage readings are erroneous readings that happen when a multimeter picks up stray voltage on a disconnected wire or an open circuit.
They might be brought on by electromagnetic noise from adjacent power lines or machinery. Users who believe there is voltage present when there isn’t may become confused or misled by them. The LoZ mode reduces the multimeter’s input impedance, draining stray voltage and providing reliable readings.
FLIR DM93:
For improved reporting and analysis, you can wirelessly send data from this multimeter to FLIR infrared cameras using the METERLiNK function. This capability allows you to combine the thermal images from the infrared camera and the electrical readings from the multimeter.
This can assist you in detecting issue areas, conducting troubleshooting, and recording your results.
