A home improvement digital level and angle gauge promising accurate angle and level checks. Saves time and reduces guesswork when bending conduit or aligning pipework. Is the KLEIN TOOLS Digital Electronic Level and Angle Gauge the reliable workshop companion tradespeople need?

⚡ At a Glance
  • Measurement Accuracy: High accuracy, comparable to a traditional bubble level
  • Best for: Electricians, plumbers and fabricators performing conduit bending and pipe alignment
  • Not ideal for: Measuring non-ferrous surfaces without an added clamp or adapter

Auto-rotating reverse-contrast display pairs with a strong magnetic base and V-groove edges. Measures 0–90 and 0–180 degrees with zero-calibration for relative angle checks.


Repeatable bends and consistent angles – With zero-calibration and wide measurement range

Zero-calibration sets a reference zero so subsequent readings are relative to that point, while the gauge supports 0–90 and 0–180 degree ranges for direct and full-span measurements. The wider range helps when accounting for springback during conduit bending.

Enables repeatable, precise bends and consistent results when shaping conduit or metalwork, reducing trial-and-error during setups.

Clear readings in dim or upside-down situations – Thanks to reverse-contrast, auto-rotating display

Reverse-contrast improves visibility in low light by swapping dark and light elements, and the display automatically rotates when turned upside-down to keep numbers upright for the user.

Speeds up checks in tight spaces or poor lighting, cutting mistakes caused by squinting or guessing the angle.

Secure hands-free positioning – With strong magnetic base and V-groove edges

A strong magnetic base attaches to ferromagnetic surfaces for stable mounting, while V-groove edges cradle pipes and conduits to maintain alignment without extra clamps.

Permits single-person operation during marking and bending, leaving hands free to hold tools and secure fittings.

✨ The 4 Key Reasons for KLEIN TOOLS Digital Electronic Level and Angle Gauge
  1. Zero-calibration – Achieve consistent angle offsets for repeat bends and measurements
  2. Auto-rotating reverse-contrast display – Read angles easily in low light and upside-down positions
  3. V-groove edges – Hold securely on conduits for accurate alignment and bending marks
  4. Strong magnetic base – Mount firmly to ferrous surfaces for hands-free measurement

❓ Frequently Asked Questions

Q: Can it measure both 0–90 and 0–180 degree angles?

A: Yes. The gauge measures in both 0–90 and 0–180 degree ranges as stated in the product description.

Q: Will it hold on pipes and conduit for hands-free use?

A: Yes. A strong magnetic base allows attachment to ferromagnetic surfaces such as pipe, conduit, saw blades, vents and ducts for hands-free positioning.

Q: Is the display readable upside down or in low light?

A: Yes. The reverse-contrast display improves low-light visibility and the screen automatically rotates when turned upside-down for easier reading.
