Relative zero is the feature; absolute angle rarely is · review
A trade angle gauge with dual 0–90° and 0–180° ranges and a V-groove machined around the base, so it sits on pipe and conduit instead of rocking on them.
What the figures leave us with Bought for the V-groove and the trade build. The absence of a published figure at this price is the notable gap.
The only gauge here designed to sit on something round.
A digital angle gauge and inclinometer that measures, transfers and checks angles, and can be used as a digital level for installation and alignment work. Dual measuring ranges of 0–90° and 0–180°, stated for pipe bending, machine alignment, metalwork and installation. A strong magnetic base holding securely on ferromagnetic surfaces such as pipes, conduit, saw blades, beams and ducts. An all-round V-groove supporting precise alignment on round surfaces.
Everything else an angle gauge sits on is flat, and a flat base handles it. Conduit, pipe and round bar are the exception, and they are exactly what an electrician or a pipefitter measures all day. Without a groove, the gauge is a rocking object reporting a number with confidence.
At the top of this hub’s range, the absence of a stated tolerance is harder to accept than on an eleven-euro tool. What Klein publishes instead is the mounting, the ranges and the intended trades — which tells you what it is for, not how close it gets.

A flat-based gauge on a pipe touches along one line and reports whatever angle you happened to hold it at. A V-groove seats on two lines and defines the orientation. Klein states an all-round V-groove for precise alignment on round surfaces.
Klein states 0–90° and 0–180° ranges, intended for pipe bending, machine alignment, metalwork and installation. A bend measured as 30° from straight and 150° included is the same bend, and the two conventions both appear on drawings.
Not in this listing. The Mcbazel and Neoteck gauges in this hub state ± 0.2°; this one states its ranges and its mounting but not its tolerance.

± 0.2° stated · 0–90° · four reference faces · aluminum, splash-proof
A MEMS-based angle gauge stating ± 0.2° over 0–90°, in a splash-proof aluminum housing with all four faces usable as a measuring reference.
Best for: The value pick: a published figure, a metal housing and four reference faces for thirteen euros.
± 0.2° stated · 4 × 90° range · built-in magnets · 3.5 × 1.7 cm (1.4 × 0.7 in) display
A four-quadrant angle gauge stating ± 0.2°, aimed at relative angles between surfaces, with a magnetic base and a stated display size.
Best for: Comparing two surfaces to each other — the job an angle gauge actually does most often.
≈ $17
4 × 90° (360°) · four magnets · absolute and relative modes · backlit
A 360° angle gauge with four base magnets and both absolute and relative measuring modes — the second mode being the one most angle work actually needs.
Best for: Work that alternates between absolute slopes and relative angles without changing tools.
