UNI-T LM320E Digital Angle Meter 2-Line Laser 4 x 90° ±0.2°

The UNI-T LM320E is a compact digital angle meter designed for construction, engineering and mechanical installation work.

It measures across a full 4 × 90° range with ±0.2° angle accuracy and supports both relative and absolute angle measurement. Two integrated laser lines provide a visual reference for alignment work, while the two-sided magnetic base allows the meter to attach securely to compatible metal surfaces.

The aluminium-alloy frame, automatically rotating colour display and rechargeable lithium battery make the LM320E suitable for portable professional use.

Specification Note

UNI-T's current table displays the resolution as ±0.05°. Resolution is ordinarily expressed as a step/value rather than an accuracy tolerance, so I have normalized this in the customer-facing listing as 0.05° Resolution, while retaining UNI-T's separately stated ±0.2° Angle Accuracy.
