This page looks at non-contact voltage testers in the research set for a DC keyword. Where the non-contact listings give a range, it is an AC range. None of the five non-contact tools below says it detects DC voltage without contact, so the page does not present any of them as a DC tester. The comparison covers stated AC ranges, alarm types, power sources, and warranty or included parts, using listing data checked on 2026-10-11.

The research set held eight listings for this keyword. Three of them are contact tools that state DC measurement, and those are mentioned in the closing sections rather than ranked here. The five picks are the listings that describe a non-contact function, so the comparison stays on one sensing method.

Quick answer

If you need non-contact detection, the listings split by range and alarm style. The Fluke 1AC II states the widest AC range, 90 to 1000V AC, and a second range of 200 to 1000V AC in a bullet. The Neoteck PM8908C and the MXCOIRTP MT01 both start at 12 volts, but both state those figures as AC ranges. The TESMEN TM-510 and ZMIWNIED FS899L are multimeters with a non-contact function, so they cover more functions than the three dedicated pens.

No listing in this group claims DC non-contact detection. If a DC question is the real job, a contact tool with a DC range is the listing type to read, and the listings for that type appear in the closing sections.

Fluke 1AC II VoltAlert Non-Contact Voltage Tester

View the Fluke 1AC II VoltAlert on Amazon

The Fluke listing gives the widest AC detection range of the five picks: 90 to 1000V AC on the main specification, and 200 to 1000V AC in one of its bullets. The bullets say the tip glows red and a beeper sounds when voltage is detected. A continuous self-test is listed, so the listing states the pen checks itself each time it is switched on. The tip is flat, the light source is one high intensity red LED, and the listing names CAT IV as its safety rating. It weighs 59 g. Two AAA alkaline batteries are included, and the listing gives a typical battery life of greater than 1-year. The item dimensions field gives 10.24 x 7.5 x 1.46 inches, which is larger than a typical pen and should be checked before buying.

Neoteck PM8908C Non Contact Voltage Detector

View the Neoteck PM8908C on Amazon

The Neoteck listing states a 12 to 1000V AC range. Its bullets describe a different alarm sound and LED level for live and null wires, which lets the user tell the two apart by the alarm. The LED lights as long as voltage is detected. The item highlight names a flashlight for outlets. The listing states battery power, an item weight of 65 g, and dimensions of 6.3 x 0.79 x 0.79 inches. It carries a CE specification mark. The bullets describe the detection as non-contact, and they do not give a DC figure anywhere in the fields reviewed.

MXCOIRTP MT01 Voltage Tester

View the MXCOIRTP MT01 on Amazon

The MXCOIRTP listing gives three AC ranges: 12V, 48V, and 70V to 1000V. Its bullets describe three sensitivity modes, with low sensitivity selected by default and a single buzzer beep at power on. The S button changes the mode. The pen has a buzzer alarm, a detection light, and a tail flashlight that the listing says can serve as an emergency light. The listing names a wire breakpoint finder in its title. The listing gives a 1 year warranty, is battery powered, and is orange. The fields reviewed do not give an item weight or dimensions for this pen.

TESMEN TM-510 Digital Multimeter

View the TESMEN TM-510 on Amazon

The TESMEN listing is a 4000 count auto-ranging multimeter that includes a non-contact voltage function. Its bullets say the non-contact mode gives a visual and audible alarm, and a bullet describes measuring the voltage on an AC wire without contact. The listing does not give a non-contact range in the fields reviewed, so the figure is not stated here. Its contact measurable voltage is 0.8 to 600 V, and its sampling rate is approximately 3 times per second. The listing states CAT II 600V, CE, and RoHS. It has a working range of 0 to 40 degrees and a storage range of minus 10 to 60 degrees. It weighs 0.1 kg and comes in green.

ZMIWNIED FS899L Digital Multimeter

View the ZMIWNIED FS899L on Amazon

The ZMIWNIED listing is primarily a 6000 count True RMS multimeter. Its bullets list NCV detection among a set of features that also include voltage, current, resistance, capacitance, and continuity measurement. The specification table gives CAT III 1000V and CAT IV 600V. The listing states a 4.8 inch color screen, a built-in flashlight, a Data Hold function, and USB-C charging with a 2-hour charge. The package includes two alligator clips and an instruction manual. The title says 2026 Upgraded, and the listed part number is FS899L-1. The NCV range is not stated in the fields reviewed, so the listing cannot be placed on the same range scale as the pens.

How we chose

The research set held eight listings for this keyword. Five describe a non-contact function, and those five are the picks. The three excluded listings are contact tools: a 2000 count AstroAI multimeter, a 2000 count LJPXHHU multimeter, and a FEAOXYO automotive test light that states a 6V, 12V, and 24V DC range. Those three are discussed in the closing sections because they state DC figures, which the non-contact picks do not. The page does not use price or rating data.

Worked example: a 12 volt DC check against the listed ranges

A 12 volt DC battery is a 12 volt DC source, and the question is whether any non-contact pick states that it detects DC. The Neoteck listing begins its range at 12V, but the listing labels that range as AC. The MXCOIRTP listing also includes a 12V range, and that range is also listed among AC ranges. Neither listing says the 12 figure applies to DC. The Fluke listing starts at 90V AC, so a 12 volt figure is outside its stated range in any case. The worked example shows why a matching number is not enough: the same 12 appears in two listings, and in both it describes AC detection.

For a 12V DC reading, the listings that state a DC range are the contact tools. The FEAOXYO listing names 6V, 12V, and 24V DC circuits, and the AstroAI listing gives DC voltage ranges of 200mV, 2V, 20V, 200V, and 600V in its specification table. Those are the right group for a DC battery reading, and they are contact tools.

What the listings do not say

No listing in the five picks states DC non-contact detection. The TESMEN and ZMIWNIED non-contact ranges are not stated in the fields reviewed, so their detection range cannot be compared with the pens. None of the five listings gives a detection distance, so the stated range figures are the only numbers that can be compared directly.

All five picks state battery power in their listing fields. The battery count and type are given only for the Fluke listing, which states two AAA alkaline batteries included.

FAQ

Does any non-contact listing in this set detect DC voltage?

No. None of the non-contact listings in the set states a DC non-contact range, and where a range is given it is an AC range. The DC figures in the set belong to contact tools, such as the AstroAI multimeter and the FEAOXYO automotive test light.

What range does the Fluke 1AC II state?

The listing states 90 to 1000V AC on its main specification. A bullet gives a second range of 200 to 1000V AC.

What does the MXCOIRTP MT01 state about sensitivity?

The listing states three sensitivity modes. It starts in low sensitivity with one buzzer beep at power on, and the S button changes the mode.

Which picks are multimeters rather than pens?

The TESMEN TM-510 and the ZMIWNIED FS899L are multimeters that include a non-contact function. Their listings also state contact measurement ranges.

Conclusion

Among these five non-contact listings, the Fluke states the widest AC range, the Neoteck and MXCOIRTP state lower starting points on AC ranges, and the TESMEN and ZMIWNIED add non-contact detection to multimeter functions. None of the five states DC non-contact detection. For a DC battery check, the listings that state DC ranges are the contact tools, and the non-contact pens should not be used as a substitute for them.
