Klein Tools NCVT-6 Non-Contact Volt Tester, 12 - 1000V AC Pen with Integrated Laser Distance Measure, LED and Audible Alarms, Pocket Clip

Excelente

If you are using this at work, like me, your master and others will most likely look at this one funny. It is a lot larger in the hands, however it detects through Safety and GFCI with no issues. The Laser distance meter is also very accurate, but I like to use it as more of an actual pointer to note out areas.

Good quality and well built design. Works as it should.

Good‘old Klein Tools quality!

TWO USEFUL FUNCTIONS BUT AT TOO LOW A PRICEFor anyone doing electrical and especially HVAC troubleshooting, the Klein Tools NCVT-4IR combines two useful functions, namely, a non-contact electrical tester and an IR thermometer. Multi-function tools usually come with compromises, and this one is no exception. At the $50 price-point, this tester is not in a sweet-spot. It needs to be cheaper for what it is ... or more expensive for what it could be. Let me explain:DEAD AS IN NO POWER DEADAs other reviewers have mentioned, my unit has gone dead more than once. Dead as in no power dead. As a former service manager for an electronics company, I was able to replicate the no power problem. The negative terminal battery connection is made between the battery space metal barrel and the battery cover end cap (that does contribute to IP-54 dust intrusion resistance). If the batteries aren't seated properly or the cover is not screwed down sufficiently, the metal contact in the end cap does not close the circuit, and the result is as has been found: no power. So far, the unit has functioned when it could get power, so I suspect it's simply the contacts. Still, a device advertised to withstand a 2 meter drop onto concrete should not be so sensitive to the battery end cap tightness. Another reviewer described a broken end-cap -- possibly caused by trying to complete the power connection. (Just a guess.)IR THERMOMETER UTILITYThe d to s ratio for this unit is 4:1 meaning the measurement circle is 1" in diameter at 4" away and 10" diameter at 40" away. That means you have to be pretty close to the object being measured to get a good picture of its temperature. The laser dot is helpful, but it also can be misleading if you think you are pinpointing the temperature. Instead, you're measuring a wide, 4:1 circle. I would prefer an 8:1 ratio, but I suspect it would be more expensive to build.IR THERMOMETER ACCURACYAccuracy could be better. All but the most expensive IR thermometers have an accuracy of about ±5ºF over the performance range. This one is no exception. My unit consistently reads low. It's normal and par for the price-point, but keep in mind this unit will give you a ballpark, not a precise IR temperature. (Emissivity is fixed at 0.95 also a common practice.)NON-CONTACT AC VOLTAGE TESTERThe non-contact voltage tester has performed as expected as long as the unit gets power from the batteries. The blue tip light confirms the function, and the chirp and a flashing red light indicate the presence of AC power. Always test on a known live circuit, but I've never had a problem with any NC tester when the indicator light was working.NOT IN A GOOD PRICE-POINTFinally, the cost or rather value. I don't want to be Klein Tools' quality control agent. I would rather the unit be cheaper and a fair value for how it currently is built or be more expensive and more reliable. If Fluke made a comparable instrument (they don't), my estimate is it would cost around $100 - $150 and be at the perfect price-point. Klein (and Fluke) -- are you listening?

Excelente, era el tester que quería, donde apuntas con el laser te toma la distancia. Muy práctico

I bought the Klein Tools distance measure - voltage tester primarily for measuring the dimensions/clearance of a complex machine. It is very flexible in measurement, providing distance in inches, feet (with fractions) and meters. It is easy to switch from inside to outside measurements with this tool. It word outdoors as well as long as the sun is not shining directly on the area where the measuring laser lands. The voltage detector provides both audio and visual conformation of the presence of voltage. The only drawback is with the three button control, it is not always clear or easy to remember which combination of buttons and length of press controls a given function.

Excelente lo recomiendo 100 % responsabilidad
