This compact inclinometer combines ABS construction with a stainless steel measuring face for durable, precise angle measurement in a portable package. Compact size and materials: Made from ABS and stainless steel sheet, the unit is compact and lightweight for easy carrying and convenient use in the field or workshop. LCD display and screen rotation: Large digital LCD numerals provide clear readability, even in dim environments. The screen rotation function automatically inverts the display for comfortable viewing in different orientations. Stainless steel measuring face: The stainless steel measuring face enables secure attachment to metal surfaces, allowing stable, reliable measurements with minimal slipping. Multifunctional design: Supports horizontal position calibration, absolute angle and relative angle measurements, and conversions between degree and slope percentage. Also converts mm/m and in/ft units, includes data hold, backlight on/off, automatic shutdown, and a 0°/90° beep for quick confirmation. 23 practical use scenarios Metal fabrication and assembly: Align brackets, fittings, and machine components by checking absolute and relative angles to ensure true perpendicularity and proper fit. Workshop and machining: Set tool angles, verify bevels, and inspect workpieces for accurate angular tolerance, with easy data hold and unit conversions for different project requirements. Field installation and construction: Use on metal structures to confirm level and inclination in tight or awkward spaces, aided by backlight and the beeper for quick onsite verification. Specifications and functions preserved Materials: ABS housing with stainless steel measuring face Display: Digital LCD with large numerals; screen rotation for convenient viewing Measurement modes: Absolute angle, relative angle, horizontal position calibration Conversions: Degree to slope percentage; mm/m and in/ft Features: Data hold, backlight on/off, automatic shutdown, 0°/90° beep Application: Suitable for metal surfaces and a variety of orientation and alignment tasks
