The Klein Tools 935DAG is presented in the listing as a digital angle gauge that can also function as a level. It is described for measuring or setting angles, comparing relative angles, and attaching to ferromagnetic surfaces such as conduit. ToolMaster has not independently verified these details.
Overview
This tool is listed with two measurement ranges: 0 to 90 degrees and 0 to 180 degrees. A zero-calibration feature is intended for checking relative angles, while the magnetic base and V-groove edges are aimed at pipe, conduit, and other suitable surfaces. The listing also identifies it as a digital level.
Listed features
Angle measurement
The listing states that the gauge measures and sets angles across 0–90° and 0–180° ranges.
Display
A reverse-contrast display and automatic rotation are listed as visibility features, including when the tool is turned upside down.
Attachment
The magnetic base is listed for ferromagnetic surfaces. V-groove edges are described for alignment on pipes and conduit.
Included items
The source lists a soft carrying case and two AAA batteries.
The source also lists an IP42 rating. Confirm the meaning and current specification before relying on that claim in a particular environment.
Who may find it useful
This type of tool may suit electrical, plumbing, HVAC, woodworking, and general workshop tasks where an angle needs to be checked or compared. The magnetic base may be useful for hands-free positioning on compatible metal surfaces. Users working with nonmagnetic materials may need another way to hold the gauge in place.
What to check before choosing
- Confirm the current measurement ranges, display behavior, and zero-calibration procedure.
- Check whether the magnetic base is appropriate for the surfaces and shapes you use.
- Verify the V-groove dimensions or fit for your pipe and conduit work.
- Confirm that the case and two AAA batteries are included with the current package.
- Review the current IP42 specification and operating limitations on the manufacturer or seller page.
Safety and use considerations
Use the gauge only in conditions suitable for the device and do not treat the listed water-and-dust resistance as waterproofing. Keep the tool stable while taking a reading, confirm that the magnet has engaged before working hands-free, and keep it clear of moving equipment. Follow the current manufacturer instructions, especially around batteries, electrical work, elevated work, and hot or contaminated surfaces.
What remains unclear
The supplied listing does not establish measurement accuracy, resolution, operating temperature, battery life, dimensions, weight, magnet holding capacity, materials, calibration interval, or the full meaning of the IP42 claim. It also does not explain the zero-calibration steps or identify every included item. Confirm these details on the current manufacturer or seller page.
Frequently asked questions
Can it measure a full 180-degree range?
The listing claims both 0–90° and 0–180° measurement ranges. The method for selecting or using each range should be confirmed.
Can it compare relative angles?
Yes, the source describes a zero-calibration feature for checking relative angles.
Will it attach to any metal?
No universal claim is established. The listing specifies ferromagnetic surfaces, so compatibility should be checked for the material and surface shape.
Is it suitable for wet locations?
The listing gives an IP42 claim, but that should not be interpreted as waterproof operation. Review the current instructions before use around moisture.
A practical conclusion
Based on the listing, the 935DAG combines digital angle readings, relative-angle checking, level use, and magnetic positioning in a compact workshop-oriented format. Its fit depends on the required accuracy, surface compatibility, environment, and confirmed package details. ToolMaster has not independently verified the supplied claims.
