Best Digital Multimeter for Checking Continuity
As an Amazon Associate we earn from qualifying purchases. Details
A continuity check tells you whether a wire, fuse or switch offers a closed path for current. A digital multimeter does this with an audible buzzer or a resistance reading. The five products below are the ones whose listings name a continuity function or buzzer in the title or bullets. Three come from the listing pull checked on 18 October 2026, and two come from the research set checked on 11 October 2026. Figures are copied from the listings, and where a listing is unclear the card says so.
Quick answer: for a continuity buzzer on a meter that also reads voltage and current, the Westinghouse and AutoViteX listings state the most functions. For a small pocket meter with a battery test, the AstroAI AM33B is the simplest listing here. For a listing that gives a numeric continuity threshold, the TESMEN TM-510 states one of about 50 ohms.

How we chose these five
We kept a multimeter when its listing names continuity or a continuity buzzer, and when it also states a voltage range. We did not include the Sperry VC61000, which is a voltage and continuity tester rather than a multimeter, so it does not give the range and current functions the buyer may need. We also excluded the ProTechTrader PDM-711 because its bullets describe the continuity buzzer but its specification sheet gives no voltage range.
- Continuity function: a buzzer or a numeric threshold, as the listing states.
- Voltage range: the AC and DC limits from the listing.
- Power source: battery type and whether batteries are included.
1. LJPXHHU XL830L Digital Multimeter
The listing says the meter measures AC and DC voltage, DC current, resistance, continuity, diodes and batteries. Its audible continuity sensor sounds when a circuit conducts, which the listing describes as a way to check that wires conduct electricity. The display is a 2.7-inch backlit LCD, and the body has a fold-out stand for hands-free reading. The listing states a 2-year quality guarantee and includes a 9 V battery, the test leads and a manual. The item weighs 166 g and measures 5.51 x 2.56 x 1.18 inches. The listing does not state a continuity threshold in ohms.

2. AstroAI AM33B Digital Multimeter
This is a compact meter with a continuity buzzer, AC and DC voltage, DC current, resistance and diode checks. The listing says it can test a 1.5 V, 9 V and 12 V battery in dedicated modes, and that the 1.5 V and 9 V modes detect battery status automatically. The listing adds that it cannot test AC current, so it should be set to the correct function before testing. The fuses are described as double protection, and the LCD is backlit. The item weighs 0.15 kg and measures 3.03 x 5.26 x 1.46 inches. Test leads and batteries are included.

3. TESMEN TM-510 Smart Digital Multimeter
The TM-510 is the only listing in this group that gives a numeric continuity threshold. The specification sheet says continuity is below approximately 50 ohms. Its auto mode switches between voltage, resistance and continuity without a dial change. The listing gives AC and DC voltage from 0.8 V to 600 V, with an accuracy of ±(1.2% + 5) on AC, and it adds a non-contact voltage alarm with light and sound. It is rated CAT II 600 V and CE and RoHS. The package includes two AAA batteries, two test leads, a storage bag and a manual. The item weighs 0.1 kg.

4. AutoViteX Electrical Test Kit with Digital Multimeter
This is a kit with a multimeter, a non-contact voltage pen and a receptacle tester. The multimeter is listed for AC voltage up to 750 V and DC voltage up to 1000 V, with DC current to 20 A. The listing states that the 20 A range is unfused and limited to 10 seconds of continuous measurement, followed by a 15-minute cooldown. The listing gives a 500 mA, 250 V fast-acting fuse for overload protection. The listing gives resistance up to 200 MΩ, capacitance up to 200 µF and a battery test at 1.5 V. The audible continuity function is listed with the meter. The outlet tester is listed for standard 110 V to 125 V circuits and does not test GFCI function or trip time.

5. Westinghouse MM600V10 True RMS Multimeter
The Westinghouse listing gives 600 V AC and DC auto-ranging voltage, a 10 A current capacity with overload protection, and an audible continuity alert. Its resistance and continuity figures are described as high-precision, but the listing does not state a continuity threshold in ohms. The 4000-count LCD is backlit and has a MAX and MIN mode that holds the highest and lowest readings for fluctuating signals. Temperature can be read in °C or °F. The listing shows CSA and UL approvals. The item weighs 6.4 ounces and measures 4.9 x 2.8 x 1.6 inches. This listing comes from the research set checked on 11 October 2026.

Worked example: a continuity reading against the 50 ohm figure
The TM-510 specification gives a continuity figure of below about 50 ohms. Take a short length of cord that reads 0.3 ohms across its two ends. That is far below the figure, so the meter would be expected to indicate continuity. Now take a switch that reads 120 ohms in the closed position. That is above the figure, so the same meter would not indicate continuity, and the switch should be checked again. The listing does not say how the meter reacts at exactly 50 ohms, so the example avoids that value. For the AM33B, a 9 V battery check uses the 9 V mode the listing names, rather than the continuity buzzer.
What the listings do not say
Only the TM-510 gives a continuity threshold, and it does not give an accuracy figure for the continuity function. The buzzer on the other four listings is described but not measured against a standard. None of the listings says how long the battery lasts when the buzzer runs, and none compares its buzzer with another meter in this group. The AutoViteX listing is the only one here that describes an unfused current range, and it does not say how the kit’s pen and outlet tester are protected.
Frequently asked questions
How does a multimeter buzzer show continuity?
The listings describe an audible continuity buzzer that sounds when the meter finds a closed path between the probes. The TM-510 listing gives the threshold as below about 50 ohms. The other four listings describe the buzzer without a figure.
Can I check continuity on a live circuit?
A continuity buzzer is normally used on a circuit that is switched off, and none of the listings in this group says otherwise. Read the safety notes on each listing before you use the continuity function.
Which of these meters reads AC current?
The AstroAI AM33B says it cannot test AC current. The LJPXHHU and AutoViteX listings name DC current. The Westinghouse listing gives a 10 A current capacity without naming AC or DC, so ask the seller if the type matters for your job.
Do these meters include batteries?
The LJPXHHU, AstroAI AM33B and TESMEN TM-510 listings say batteries are included. The AutoViteX and Westinghouse listings do not say whether batteries come in the box.
Which should I buy for continuity only?
For continuity alone, the TESMEN TM-510 is the only one with a stated threshold, so it gives the clearest figure. If you also need a battery test and a compact body, the AstroAI AM33B covers both.
Conclusion
For a continuity check with a stated figure, the TESMEN TM-510 gives the clearest threshold, and its auto mode saves a dial change. The AstroAI AM33B suits a pocket meter with a battery test, and the Westinghouse listing is the only single meter here that states a current capacity. The AutoViteX kit is worth considering if you also want a non-contact pen and an outlet tester, provided you read its current and fuse notes. Check the stated voltage and current ranges against your job before you buy.
