Dual-axis inclinometer DMI810/820

Virtual COM portdigitalUSB

General description
DMI810/DMI820 is a digital display inclinometer designed for industrial angle control and measurement. It employs micro-mechanical control principles with a dual-core measurement unit, enabling X/Y compensation, interleaved angle and temperature-drift compensation for stable long-term performance. The instrument supports single- and dual-axis operation, up to ±30° range, 0.001° resolution and accuracy <0.005° (full scale). Side and bottom magnetic mounting, data storage and multiple measurement modes are provided.

Main features
