Product Description

The AC voltage tester handles 12V to 240V AC voltage and four useful voltage levels similar to those commonly used for residential purposes
DC voltage is tested ranging from 1 to 1000. Five voltage levels are used to match up with commonly used DC voltages ranging from 5V to more than 17V-24V in four useful levels
A bright LED illuminates when voltage is detected to show what kind and how high it is
It is built to withstand a 9 on the scale of 1-9. The drop is 9 feet (3 m)
When measuring DC voltage, indicates which direction the voltage is going

Questions & Answers

What is the place of production?

It is China

Do you think this will work on a 12V automotive battery?

Testing is currently being done by two testers. I bought the one that costs If you order the more expensive one, it says 12/240 volts, but the 99 only says 24/240 volts. Make sure you order the one that fits the needs you have.

What are the benefits?

In short, yes. It works well, and I've used it many times already.

Can this be used to ?

I don't believe it does

This is a great price for such a handy tester
5/5

To keep in my tool pouch for household and garage stuff as well as maintaining a few rental properties, I wanted a small tester. My Fluke MM and my Klein clamp meter are good for checking for heat at times, but sometimes you just want a quick check for it. A benefit of this meter, besides it being small and pretty rugged, is that when compared to a plug-in one, it is a lot cheaper It's a stylish outlet tester, and the leads you get can be used to actually test terminals, breakers, or lugs. Furthermore, outlets are also available for you to check. The fact that there are no batteries is also appealing to me. A non-profit organization However, they are sometimes unreliable and inaccurate. Contact voltage testers are also effective, but they are not precise. It may just be a matter of preference, but my only complaint is that I would have preferred the clip to be oriented the other way around. It would be even better if the clip could be reversed or removed. They have the wires exiting at the top of the clip, which means if you clip it to your pocket like a knife, the lead wires will loop up before looping back down to the tester where the leads are stored. In the case of 180-degree clips Due to its different angle, clipping it would make it a lot cleaner because the lead wires would be tucked into your pocket or tool pouch and nothing would stick out. I don't think it matters much whether I prefer it this way or not it might be different for someone else, but either way it doesn't matter to me - The fact that it costs $8 doesn't hurt either, it's killer. There are limits to how much you can complain. When all you are doing is testing outlets, a plug-in tester can get the job done Faster test results are going to appear in tester. It's fine to test for only if something is hot, but it may not be as accurate as a test for It may be more effective to use a contact tester. However, it is capable of testing for different voltages, so this little guy is quite adequate. It is no secret that Klein has a number of solid testing tools.

It is the perfect tester for those who aren't handy often
5/5

There is nothing better than a simple, user-friendly app like this It would make a wonderful gift for anyone! It's good enough for professionals, as well as those of us who change outlets and switches from time to time This voltage tester is very safe to use and accurately predicts voltage levels before you start your electrical project.

I would like the wires to be a bit longer, but it works OK
5/5

Our house was in need of a few new electrical outlets. We installed it It would've been nice if the wires were a little longer, as another reviewer said. While inserting the probes and holding the tester at the same time, it is challenging to keep the tester upright. I inevitably insert the probes upside down then leave the tester hanging. To determine whether the outlet has power, I only need to know if it is connected. The program does the job, but it's not great.

A quality tester of the highest order! As a technician for appliance repair, that would be perfect for me! The orange color of these new models makes them easy to find in a tool box
5/5

They are brighter and faster than the old models.

They are a good fit for what they are
5/5

There are several reviews that mention the short cords, they are short. They would likely cheer if they were longer because they would think they were too long. Carrying around a multimeter doesn't make much sense in the end. When it comes down to it, this little thing works fine most of the time. It is the kind of thing I use pretty often. I am glad I bought it.

It's great to have you test for us
5/5

This is a great Whenever I am at an appliance outlet, it helps me to test the 220 volts. Small enough to easily fit in a pocket, so I can carry it everywhere I go.

The voltage of light switches and lights is tested
5/5

This voltage test was performed by Receptacles and light switches can be tested for live voltage by utilizing this device. Receptacles are extended into the probes.
