Bosch GAM 220 Professional digitale hoekmeter 0 - 220°

The Bosch GAM 220 Professional is a compact digital angle measurer designed for accurate measurement of angles from 0° to 220°. With a 0.4 m length and a user-friendly digital display, this tool provides clear readings for on-site layout and verification tasks. Powered by a single 1.5 V battery, the GAM 220 combines portability with straightforward operation to support a range of professional measuring needs.

Advantages

The device offers a wide measuring range up to 220°, enabling measurements of both acute and reflex angles without repositioning. Its compact construction and lightweight design make it easy to handle in confined spaces and for overhead work. The digital readout delivers precise numerical values that reduce interpretation errors compared with analog methods. Battery operation ensures it's ready for field use and simple to replace when needed.

Suitable for

• Carpentry and joinery angle checks
• Installation of trim, mouldings and stair components
• Metalwork layout and sheet bending verification
• On-site inspection and quick layout tasks for installers and contractors

Key specifications

• Measuring range: 0°–220°
• Length: 0.4 m
• Power supply: 1.5 V battery
• Display: digital readout for angle values
• Weight and form factor: compact, lightweight design for handheld use

How to use

Place the GAM 220 on the surfaces or edges that define the angle to be measured, aligning the instrument so both measurement arms or reference faces contact the workpieces. Switch on the unit and read the angle value from the digital display. For measurements beyond a single face, reposition as required within the instrument's 0°–220° range and record the displayed value. Turn off the device after use to preserve battery life.

Recommendations

For reliable results, ensure contact surfaces are clean and free of debris before measuring. Calibrate or verify the tool against a known angle if high-precision comparison is required. Replace the 1.5 V battery when display dimness or inconsistent readings occur. Store the measurer in a protective case or dry environment to avoid mechanical damage.
