Klein Tools 935DAG Features

The Klein Tools Digital Angle Gauge and Level features 0-90° and 0-180° measurement ranges allow for a wide range of applications like electrical, plumbing, HVAC, and carpentry jobs. It features a strong rare earth magnet at the base, as well as V-groove edges, which allows it to attach easily and truly to conduit, pipe, sawblades, vents, ducts, and other ferromagnetic surfaces.

Dimly-lit areas are no problem for this tool; it features a high-vis, reverse-contrast display that even auto rotates when you hang it upside down.

Klein has fashioned the Digital Angle Gauge and Level from shock-resistant ABS plastic, which gives it drop protection up to 6.6 feet. An IP42 rating protects the unit from some water and dust ingress.

At 3.5 oz, and with a 2.36″x2.2″x1.2″ frame, the Klein Tools Digital Angle Gauge and Level can be thrown into a pocket or toolbag easily.


Right now, you can pick up the Klein Digital Angle Gauge and Level for $35.99. It comes with a soft carrying case and two AAA batteries, as well as Klein’s 2-year limited warranty.

A Few Thoughts

With a focus on the electrical trade, it’s no surprise to see Klein target a design that’s compatible with conduit. There’s some legitimate plumbing use as well to check your slopes on installs.

Since it reads degrees to a precision level of 0.1º, it’s useful to help calibrate your miter saw and table saw, too. Its accuracy is ±0.1° when you’re checking 0º, 90º, and 180º, but drops to ±0.2° at all others. That’s on par with other angle gauges in this price range, but something for fine finish carpenters and woodworkers to keep in mind.

I really like the reverse-contrast, backlit screen. It seems super-easy to read in any light conditions.

IP42 protection gives the meter some resistance to dust and water, but not a ton. It will keep out dust and particles over 1mm in diameter and it can handle dripping water hitting it up to a 15º angle. It’s not something you can leave out in a storm and expect it to survive. Still, it’s a tool you expect to use mainly indoors.

Overall, this looks like a useful product from Klein that’s priced where it belongs. What do you think? Let us know in the comments below!
