ET45 Klein Tools Voltage Tester Makes Electrical Presence Testing Super Simple
Not every tool in your bag has to cost your firstborn child, take up a ton of space, and require an engineering degree to understand. The ET45 Klein Tools Voltage Tester not only makes testing voltages simple and takes up so little space that you can carry it around in the front pocket of your shirt.

- IP44 rating for dust and water ingress protection
- Pocket clip
- MSRP: $8.99
What’s the Big Deal?
The size of the Klein Tools Voltage Tester isn’t revolutionary in the grand scheme of things. There are plenty of voltage testers on the market that aren’t much bigger than your standard ballpoint pen.
This one forgoes the batteries and uses the outlet voltage to power the LEDs in the display. This keeps the overall size and weight of the unit light and compact enough to fit easily into your front pocket.
The ET45 tests both AC and DC voltages. It indicates AC voltages at 24V, 48V, 120V, and 240V, and DC voltages at 32V, 64V, 160V, and 330V.
It comes with two non-interchangeable test leads that store up nicely in the built-in holder. Incidentally, it also doubles as a spacer for testing tamper-resistant outlets.
The ET45 Klein Voltage Tester carries a CATIII 350V, Class 2, double insulation safety rating. An IP44 rating ensures protection against dust and water and it can withstand drops from 9.9 ft or less.
You don’t need some crazy-expensive or complex multimeter to test for voltage at the basic level. For $8.99, the ET45 Klein Tools Voltage Tester confirms the presence without a lot of extra complication. It’s not as convenient as a non-contact voltage tester, but it’s less expensive and tells you what voltage range you’re working in.
If you’re working on electronics, Klein also has the ET40 that hits 1.5V, 9V, 12V, and 17V+ levels on the AC side.
This is something every Pro and homeowner should have. It’s also a great “welcome to the job” gift for your new apprentice while you’re teaching him or her to check if the power’s on every time.
