Digital Angle Meter 400mm Electronic Level Ruler with Magnetic Base and Flip-Up LCD

This digital angle meter provides precise measurement of slopes and inclines in both degrees and mm/m, reaching up to 100mm/m. The 400mm electronic level ruler is equipped with four built-in magnets on the base plate, allowing hands-free attachment to metal surfaces during use. The flip-up LCD display keeps the reading always in the correct upright position, which is particularly helpful when working overhead. You can measure all angles in either a complete 360° range or as four separate 90° quadrants, giving flexibility for different tasks such as confirming horizontal and vertical surfaces or checking the rise and fall of slopes.

Features and Construction

This digital level ruler combines precision electronics with a practical magnetic base for reliable angle measurement. The device includes a hold function to freeze readings, absolute and relative measurement modes, and an auto power-off feature to conserve battery life.

Material and Build

The ruler body is made from durable plastic with a built-in electronic sensor. The base plate incorporates four magnets, allowing the level to attach securely to metal surfaces during measurement. The unit operates on two 1.5V AAA batteries (not included) and offers a battery life of over 2000 hours.

Size and Practical Fit

With dimensions of approximately 41.5 x 5.0 x 2.0 cm (L x W x H), the digital level is compact enough for toolboxes and portable use. The 400mm length provides a stable base for measuring longer surfaces while remaining easy to handle.

Uses and Placement

This device is suitable for a variety of construction, woodworking, and DIY tasks that require accurate angle and slope measurement. The magnetic base allows it to be placed on metal beams, machine parts, or other ferrous surfaces.

Professional and Trades Use

For tradespeople, the digital level is useful for setting up machinery, checking roof pitches, aligning pipes, or confirming levels on steel structures. The flip-up LCD and hold function aid in recording measurements where direct line-of-sight is limited.

Everyday Home Use

Home DIY enthusiasts can use it for hanging shelves, fitting kitchen units, levelling flooring, or checking the angle of steps. The clear display and simple controls make it accessible for non-professional users.

Benefits and Buying Value

This digital angle meter offers reliable measurement accuracy with a long battery life, reducing the need for frequent battery changes. The magnetic base and upright display improve efficiency on site.

Reuse and Low Maintenance

The auto power-off function helps preserve battery life, and the durable plastic construction withstands typical workshop conditions. No specialist cleaning or calibration is needed for standard use.

Why Choose This Product

With precision to 0.1°, a reading range of 0–360°, and both degree and mm/m display options, this device covers multiple angle measurement needs in one tool. The convenient magnetic attachment and simple absolute/relative measurement modes make it a practical choice for accurate levelling tasks.
