UNI-T LM320D Digital Angle Meter
The UNI-T LM320D is a compact, rugged digital angle meter built with an aluminum-alloy + ABS body and a high-definition backlit display. It supports a full 4×90° measurement range and displays real-time tilt data clearly with automatic screen rotation. Designed for on-site use, the LM320D pairs portability with a strong two-sided magnetic base for quick hands-free positioning on ferrous surfaces.
The meter offers absolute and relative angle measurement modes (you can set any 0° reference), data-hold and angle-hold functions, and multiple unit options (°, %, mm/m, in/ft) for flexible readouts. Type-C rechargeable power and straightforward controls let technicians power, lock, and switch units quickly; auto power-off conserves battery between uses. The device is sized for easy one-hand operation in tight workspaces.
With a 3.7 V / 1000 mAh rechargeable battery offering long runtime, the LM320D is built to withstand routine site use in a 0 °C–50 °C working range. Its durable construction, intuitive calibration/auto-zero procedures and compact footprint make it well suited to construction, mechanical installation and trade-work where fast, repeatable angle checks are needed.
