Voltage Testers: Specs Compared
As an Amazon Associate we earn from qualifying purchases. Details
None of the twelve products in the research set for this keyword is a Salisbury model, so this page does not compare any Salisbury tester. It compares five voltage testers from the same set by their listed AC and DC ranges, detection type and identifiers. Figures come from the listing data dated 11 October 2026, and each listing claim is shown as the listing states it.
Quick answer: for a 120 V or 240 V outlet, the TESMEN TM-510 and the four pens all list a top range high enough to cover the reading. The TM-510 lists 0.8 to 600 V AC and DC, and the four pens list 1000 V AC. For a non-contact check at the outlet, pick one of the pens. For a reading in volts, pick the TM-510.

How we chose these five
The set holds twelve products: four pens, four multimeters, three automotive test lights and a high-potential tester. We kept the four pens and the TM-510, because their listings state a voltage range in volts that a reader can check at an outlet. The test lights are for car circuits, and the other multimeters and the high-potential tester are general-purpose meters or withstand testers, so this page leaves them out.
1. Klein Tools NCVT1P Voltage Tester
The Klein pen is listed for 50 to 1000 V AC, with a CAT IV 1000 V rating. The listing describes detection in cables, cords, breakers, switches, outlets and wires. The green LED shows the pen is on, and a red flash with a beep shows voltage. It takes two AAA batteries, which are included, and has an auto power-off function. Check the Klein NCVT1P on Amazon.
2. Fluke 1AC II VoltAlert
The Fluke pen states 90 to 1000 V AC in its specs field, and a bullet also gives 200 to 1000 V AC. Its tip glows red and a beeper sounds when voltage is present. The listing states a continuous self-test, a silent mode, and a typical battery life of more than one year. The warranty is two years. Check the Fluke 1AC II on Amazon.
3. Neoteck PM8908C Non-Contact Voltage Detector
The Neoteck pen covers 12 to 1000 V AC and uses audible beeps and LED alerts. Its bullets describe a flashlight that doubles as an emergency light. The listing gives an 18-month warranty and a weight of 65 g. Its model field reads PM8908C and its part number field reads TL163-US. Check the Neoteck PM8908C on Amazon.
4. MXCOIRTP MT01 Voltage Tester
The MXCOIRTP pen names three ranges: 12 V, 48 V, and 70 to 1000 V AC. The listing describes three sensitivity modes, a detection light and a tail flashlight. The warranty is one year. The listing does not state a weight. Check the MXCOIRTP MT01 on Amazon.
5. TESMEN TM-510 Digital Multimeter with NCV
The TM-510 is a 4000-count multimeter with a non-contact voltage function. The listing states a measurable voltage of 0.8 to 600 V, with AC and DC voltage, resistance and continuity in its auto mode. It states a 40 Hz to 1 kHz True RMS frequency response, data hold, auto shutdown and a flashlight. The listing also says “CAN’T MEASURE CURRENT”. It states CAT II 600 V. The listed weight is 0.1 kg. Check the TESMEN TM-510 on Amazon.
Worked example: a 240 V circuit against each top range
Take a 240 V dryer outlet. On the TESMEN TM-510, the listed top range is 600 V, so 240 V sits at 40 percent of it. The four pens list 1000 V AC as the top, so 240 V sits at 24 percent of that top range. A pen that detects through insulation gives an alarm but no number, so use the TM-510 when you need a value in volts.
For a 120 V outlet, the same arithmetic gives 20 percent of 600 V on the TM-510 and 12 percent of 1000 V on the pens. The Fluke’s 90 V floor and the Klein’s 50 V floor both sit below 120 V, so both pens detect a standard outlet on the listed data. These are listing ranges, not measurements, and the listings do not say how each device behaves near its top range.
What the listings do not say
- Salisbury: no product in the set is a Salisbury model, so the set cannot show how a Salisbury tester compares.
- Current: the TM-510 listing says it cannot measure current, so the table gives no current figure for it.
- Weights: the MXCOIRTP listing gives a warranty but no weight.
- Battery life: the only battery-life figure among these five is the Fluke listing’s more than one year. The Klein listing names an auto power-off function without a battery life.
Frequently asked questions
Does this set include a Salisbury voltage tester?
No. None of the twelve products in the research set is a Salisbury model, so this page does not compare any Salisbury tester.
Which tester here has the highest listed AC range?
The Klein NCVT1P, Fluke 1AC II, Neoteck PM8908C and MXCOIRTP MT01 each list 1000 V AC as their top range. The TESMEN TM-510 lists 600 V.
Do the non-contact pens here measure DC?
The listings for the Klein, Fluke, Neoteck and MXCOIRTP pens describe AC detection only.
Which pens here state a warranty?
The Fluke 1AC II lists two years, the Neoteck PM8908C lists 18 months, and the MXCOIRTP MT01 lists one year. The Klein listing points to the manufacturer’s website for its warranty.
Does the TESMEN TM-510 measure current?
No. Its listing says it cannot measure current.
Conclusion
For a quick check at an outlet, a non-contact pen such as the Klein NCVT1P, Fluke 1AC II, Neoteck PM8908C or MXCOIRTP MT01 gives an alarm with no reading. For a value in volts, the TESMEN TM-510 lists 0.8 to 600 V AC and DC. None of the products is a Salisbury model, so a Salisbury buyer will need a separate listing to compare.
