Most devices can only be used on a specific type of circuits, either alternating current (AC) circuits or direct current (DC) circuits.
13 Best Voltage Meters
1. Kuman- Best Voltage Tester for Electricians
This Kuman is widely considered as the best wireless voltage test for the money because it’s useful in making base measurements, as can be expected from a device. These include electromotive force (V), the testing wide range for which it’s mainly designed for, as well as power in watts, energy in kilowatts, voltage and current in amps.
We find this device in many residential and commercial applications, particularly in households and businesses that want to monitor their month-to-month consumption. Take note that it isn’t like the analog multimeters with test probes and the like.
2. KAIWEETS HT100- Best Non Contact Voltage Tester
The Kaiweets HT100 is a pro-grade device for alternating current (AC) circuits and, as such, we consider it as the best multimeter testing kit. Most, if not all, household outlets and appliances are on AC circuits. With its adjustable sensor indicators and audible beeps, it’s easy to use, even for a beginner hobbyist, and its readings are easy to read from the backlit LCD display.
It has a CAT III safety rating up to 1000V and CAT IV up to 600V. There’s a warning beep and a red glow from the screen when electromotive force (V) exceeds 90V, a good safety feature. The beeps increase in frequency, too, as the electromotive force (V) ratings increase and the screen displays red (live wire) or green (null wire) light.
3. HANMER Multimeter- Best Voltage and Continuity Tester
If you’re looking for the best multimeter for low volt lighting with a budget-friendly price, then this true rms multimeter is our recommended unit. Aside from measuring DC and AC current, resistance, voltage and electromotive force (V), it’s also useful in measuring resistance, capacitance, frequency and continuity. You should then be able to use it in running automotive diagnostics as well as in residential and commercial applications.
This mini multimeter comes with several accessories, such as the test probes and jacks, so it can be used out of the box – after an initial calibration, if you want. It’s small enough to be carried in the palm of your hand or in your jeans pocket or tool bag, too.
4. B&K Precision- Best Electrical Voltage Tester
With its high level of accuracy, the B&K Precision PR 28A probe is a must-have accessory for the best multimeter tester probe for home! It has a higher-than-expected level of accuracy when paired with a high quality multimeter. We suggest setting realistic expectations since its performance will depend on the overall quality of the digital multimeter it’s paired with.
For example, on a cheap automotive multimeter with 7 megohms, the reading will be low. But on a electric tester with 11 megohms, it will be slightly high. Overall, it’s a probe that can be used with most digital meters within the recommended 40k VDC or 20kVac Max input electromotive force (V). You can then use it for most higher electromotive force (V) testing purposes although we don’t recommend applications beyond light industry.
5. B&K Precision- Best Voltage Pen Tester
The best rated non contact voltage tester should ideally have a compact design so that it can be used in tight spaces, as is the case for many HVAC repair and replacement jobs. This is the case for the B&K Precision HV44A electric tester! Unlike most HVAC digital multimeters, however, there are no separate cables and plugs with it.
Instead, the probe and the electric tester are in a single unit. You just have to point the end of the probe into the circuit and see the reading on the meter below it.
6. Digital Insulation Resistance Tester- Best AC Voltage Detector
The BT-6688B hvac multimeter is the best multimeter for a do it yourself enthusiast because it’s easy to use and maintain. You can use it out-of-the-box, too, since it already comes with six pre-installed batteries and the test probes. You may have to pre-calibrate it but it’s a quick and easy job.

Buyers’ Guide for Best Voltage Tester: Your Questions Answered Here
What type of electromotive force (V) electric tester should I buy?
The ultimate electromotive force (V) digital multimeter depends on your specific needs and wants of the device. You must then first determine exactly what you will be using a multimeter for before making your choice. You will have an easier time narrowing down your choices, too.
For example, you may want the B&K Precision HV44A digital multimeter because of its self-contained design suitable for residential and commercial uses. But it isn’t a safe device for heavy-duty testing and, thus, your best choice is the TIC-300 Pro if you’re testing transmission lines and the like.
You will find two types of multimeters with each type being used for specific purposes. Some are permanently mounted on a panel, which are usually found on generators and other fixed equipment. Some are portable electric tester that can be used for a wide range of electrical current work.
These are also available in two types based on their display panel. Analog multimeters have arrows pointing to the number on a panel while digital show the reading on an LCD display.
Emphasis must also be made that your choice in a digital multimeter will be influenced by the level of accuracy desired. If you’re using it for residential applications, then a lower level of accuracy is acceptable. But a higher accuracy level is a must for commercial and industrial uses.
Tip: Periodically calibrate your digital multimeter so that it’s within its specified tolerance, usually stated by the manufacturer on the instruction manual. The calibration should be made against the Weston cell or other electromotive force (V) standards.
How do I know what voltage range I need for a voltage electric tester?
Again, it depends on your specific needs and wants in a electric tester! If you want a more versatile device, you may want to look for one with an adjustable range. You can them increase or decrease its range as needed.
A few tips to keep in mind when doing so:
- To increase the range of an item, connect it to high resistors compatible with its series.
- To decrease its range, reduce its resistance, usually by putting the right resistance in parallel with it.
You should also select a range above the maximum expected electromotive force (V), an easy task for a manual ranging tester. But if it doesn’t have a manual ranging option, the auto-ranging digital multimeter function will do the job.
Does it matter which wire is red and which is black on my electromotive force (V)meter?
Yes, it does on old-school analog multimeters. If the probes are incorrectly connected or the selected electromotive force (V) range is incorrect, the electricity flow will likely push the needle backwards instead of forwards. The needle can also be “pegged” wherein it’s pushed too far, which can happen when its setting is 10V but it’s pushed into 40V instead. In either case, there may be inaccurate measurements, even permanent damage, in the future.
Always read the instruction manual on an electric tester before using it, even when you’re already experienced in handling both analog multimeters and digital multimeters. There may be slight differences in the design, perhaps a few extra safety precautions that must be taken.
Do I need to calibrate my electromotive force (V) electric tester before I use it and why?
Keep in mind that digital multimeters are designed to measure a specific quantity – electromotive force (V) – and display the reading that changes in a predictable way. For example, the reading may be directly proportional to the square root or cube in relation to the quantity being measured. The best multimeters should give precise readings up to a certain point.
But even the best voltmeters will require calibration before their first use. This is because the starting zero point must be fixed and marked first, and this is where calibration comes in. Calibration make sure that the actual response is the exact response expected of the device being used.
And then there’s the matter of the frequency of calibration. There’s no one-size-fits-all calibration recommendations but these guidelines are useful.
- Check the calibration interval recommended by the manufacturer.
- Calibrate before a major project and make sure that the devices will not be used before the intended testing jobs
- Calibrate after a major project to determine whether electric testers provided accurate readings
- Calibrate after the device has been dropped to the floor, or its internal overload safety protection has been knocked out, or it has absorbed physical impact from above. Even a small yet visible physical defect on the device, such as a broken connector or a dent on the plug, should be enough reason for an out-of-schedule calibration.
You may also set your own calibration schedule depending on your frequency of use of the device. The more frequently you use it, the shorter the interval between calibrations, if possible.
What happens when I switch the probes of the electromotive force (V) electric tester?
It sound like a recipe for disaster – the red and black probes have been exchanged on a digital multimeter. But it isn’t! There will be no explosions and other bad things that will happen in this instance.
Instead, the reading on the device will be negative. This is because the device measures electromotive force (V) as it relates to the common probe. Keep in mind that the “+” on a battery in comparison with its “-“ is 1.5V. If the probes are switched, the “+” becomes the zero or common point.
As such, the “-“ of the battery in comparison with the new common point is -1.5V. Again, it’s just a negative reading but there will no negative things happening.
What does the accuracy of the electromotive force (V) electric tester mean?[/caption]
The accuracy of a electric tester refers to the closeness of the indicated value, as shown on its screen, to the true rms value of the signal being measured. In the case of analog multimeters, their accuracy levels are listed as a percentage of the full-scale measurement.
If the measured value is near to full scale, the accuracy level as published by the manufacturer is meaningful. If the measured value is 2/3 above full scale at least, then it’s still an acceptable level of accuracy.
The rule of thumb here is that the further away the displayed measurement from full scale, the greater its possible deviation from the signal’s true rms value. This is when it’s seen as a percentage of reading instead of percentage of full scale.
For instance, if an analog multimeter has a +/-3% accuracy at a 0 to 100V range, its pointer can then be about 3V below or above the signal’s true rms value. While 3% doesn’t seem like a huge deviation, it can add up over time and it can affect the decisions made by the technician or electrician.
Do all electromotive force (V) electric tester have overload safety protection?
Most, if not all, devices have overload safety protection as part of their safety measures. The overload protection features prevent damage to the electric tester itself and the circuits on which these are being used, as well as for the protection of the user. These can include ceramic fuses that protect against the risk of over-current; many devices have high input impedance on their volts/ohms terminals for this purpose.
Other safety measures include overvoltage protection through a protection circuit and a thermal protection circuit for the detection of overvoltage.
