Klein ET60 Voltage Tester Needs No Batteries

Klein ET60 Voltage Tester

Klein Tools recently introduced two new voltage testers that use standard replaceable test leads for Electrical Pros. First, the Klein ET60 Voltage Tester needs no batteries as it measures AC/DC voltage up to 600V. Second, the ET250 voltage and continuity tester features an LCD display, measures AC/DC voltage up to 600V, and can test GFCI-protected circuits. Both voltage testers have a tough meter design and are rated CAT IV 600V for safety.


“We know that many electricians personally own dedicated voltage testers and our research found that more than half of these customers express a preference for digital LCD displays on their testers. Knowing this, we decided to enhance our voltage tester line by delivering these new durable, easy-to-read voltage testers that use standard replaceable multimeter test leads instead of the more commonly used dedicated fixed cord sets.”

Our Take

There are a lot of things to like about Klein Tools, not the least of which is the company’s ability to hear and respond to its customer’s needs and provide great products to meet those needs. Brand new from Klein are two new voltage testers – the Klein ET60 and the Klein ET250. Both measure up to 600V, have Cat IV ratings, and both have Klein’s Tough Meter attributes that seem to be quite popular with Pros. The Tough Meter design means the tool can take a lickin’ and keep on tickin’, in a manner of speaking. Please don’t actually lick your meters!

We really like the large digital display of the ET250 but we also like the simplicity of the ET60. Both designs are a step up from the handy and smaller non-contact voltage testers (NCTVs), which simply tell you if there is current flowing through the circuit but can’t tell you how much. Of course, before any electrical work can commence, an electrician must know what state a circuit is in, and the voltage meter is the tool to use. The ET60 doesn’t need batteries as it uses the circuit’s power for its power, and so consequently, you don’t have to wonder if you’re not receiving a reading from the circuit because the meter’s batteries are dead. That’s pretty cool. It’s like a safety feature inside a safety tool, which is the meter itself.

Both meters use standard test leads which makes replacement easy and the integrated lead holders on the back both stow and position the leads for circuit testing. Couple those features with the solid-state design and low impedance, and we think Klein fans will have a new tool to pick up.
