Best Voltage Amperage Tester

This page covers the three meters in the research set whose listings state a current measurement alongside voltage: an AstroAI 2000 count multimeter, an LJPXHHU 2000 count multimeter, and a ZMIWNIED FS899L 6000 count meter. The listings were checked on 2026-10-11. Fluke, Klein, Neoteck, MXCOIRTP, WINAMOO, JASTIND, FEAOXYO, TESMEN, and MULBRANTEX listings do not state a current measurement, so they are not compared here.
A current figure on a listing is only as useful as the range and fuse data behind it. Two of the three listings give current as a function in their bullets without a range, so the comparison below states where a range is missing rather than filling it in.
Quick answer
The AstroAI listing is the only one of the three that gives current ranges in its specification table. It states DC current ranges of 200 microamps, 200 milliamps, and 10 amps, and it lists a fuse for each of the two current inputs. The LJPXHHU and ZMIWNIED listings both name DC or AC current as a function, but neither gives a current range in the fields reviewed. The ZMIWNIED listing is the only one with a stated CAT III 1000V rating.
If the current range is the deciding figure, check the product page for the AstroAI range and for the other two listings before ordering.
Comparison table
| Listing | Stated voltage functions | Stated current functions | Current range or fuse data | Other stated detail |

AstroAI Digital Multimeter Tester 2000 Counts
View the AstroAI multimeter on Amazon
The AstroAI listing, model AM33D, is the only one of the three with a current table. Its DC current line gives 200 microamps, 200 milliamps, and 10 amps, with an accuracy of plus or minus 1.2 percent plus 3 digits. The fuse data lists 250 mA at 250 V for the milliamp input and 10 A at 250 V for the 10 amp input. The bullets say the meter cannot test all AC current, so the AC current capability is limited, and the listing does not give an AC current range in its table. The listing states a 0.15 kg weight, a 2000 count display, and a 3 Year Warranty. Its power source is shown as 2 x 1.5 V AAA batteries in the table, while the included parts name a 9V battery.
LJPXHHU XL830L Digital Multimeter
View the LJPXHHU XL830L on Amazon
The LJPXHHU listing states that it measures AC and DC voltage, DC current, resistance, continuity, diodes, and batteries. The title repeats the AC and DC current wording. The fields reviewed do not give a DC current range, a fuse rating, or an accuracy line for current, so the current capability is known only as a named function. The bullets describe overload protection, a 2.7 inch backlit LCD, and a data hold function. The item weighs 166 g and measures 5.51 x 2.56 x 1.18 inches. Because no current range is stated, this listing cannot be compared with the AstroAI current figures on a range basis.
ZMIWNIED FS899L Digital Multimeter
View the ZMIWNIED FS899L on Amazon
The ZMIWNIED listing states a 6000 count True RMS auto-ranging meter. Its precision bullet names AC and DC voltage, current, resistance, and capacitance. The specification table gives CAT III 1000V and CAT IV 600V ratings. The listing does not state a current range or a current fuse rating in the fields reviewed. The listing names a 4.8 inch color screen, a built-in flashlight, a Data Hold function, and a USB-C rechargeable battery with a fast 2-hour charge. Two alligator clips and an instruction manual are included, and the part number is FS899L-1.
How we chose
The research set held twelve listings for the voltage and amperage keyword. Three state a current measurement alongside voltage, and those three are compared here. The other nine do not state a current measurement in the fields reviewed. The page does not use price or rating data, and the title is kept because these three listings support it.
Worked example: a 10 amp DC reading against the AstroAI accuracy line
The AstroAI DC current line gives 10 amps as the top range and an accuracy of plus or minus 1.2 percent plus 3 digits. At a reading of 10 amps, the percentage part of that accuracy is 0.12 amps. The digit term is a count of the last displayed digit, so it adds a further amount that depends on the display resolution. The 10 amp input is fused at 10 A and 250 V, according to the same table. A shopper who expects currents near the top of that range would have the 0.12 amp percentage figure to work with, and would need the digit term from the full listing to finish the calculation.
The same test cannot be run on the LJPXHHU or ZMIWNIED listings from the fields reviewed. Each names current as a function but gives no range, so no percentage term or fuse rating can be stated for them.
What the listings do not say
No listing in this set gives a current accuracy figure for the LJPXHHU or ZMIWNIED meters in the fields reviewed. The AstroAI listing does not give an AC current range in its table, and its bullets say that not all AC current can be tested. The listings do not describe how the current input is connected, so the setup for current measurement has to be read from each product manual.
The AstroAI listing states two different power sources. The table gives 2 x 1.5 V AAA batteries, and the included parts name a 9V 6F22 battery. The ZMIWNIED listing names a rechargeable battery through USB-C, and the LJPXHHU listing names battery power without a battery type.
FAQ
Which of these meters states a current range?
Only the AstroAI listing gives current ranges, which are 200 microamps, 200 milliamps, and 10 amps for DC current. The LJPXHHU and ZMIWNIED listings name current as a function without a range.
Does the AstroAI meter measure AC current?
The AstroAI bullets say the meter cannot test all AC current, and the specification table does not give an AC current range. The AC current capability should be checked on the product page.
Does the ZMIWNIED meter measure current?
The ZMIWNIED listing names AC and DC current in its bullets. It does not give a current range or fuse rating in the fields reviewed.
Which of these meters has the strongest safety rating?
The ZMIWNIED listing states CAT III 1000V and CAT IV 600V. The AstroAI listing states CAT II 600 V and CAT III 300 V. The LJPXHHU listing names safety standards without a category.
Conclusion
Three meters in this set state voltage and current, but only the AstroAI listing gives the current figures needed to check a range and a fuse. The ZMIWNIED listing has the stronger safety rating and the higher count, and the LJPXHHU listing names current without a range. For a current job where the range matters, the AstroAI table is the only one of the three that can be read against a number.
