400mm/16inch Digital Spirit Level Finder with Digital Audio Indicator Aluminum Alloy Angle Finder with Magnetic Base Measuring Tools Angle Gauge Large Clear LED Display

High Precision Digital Level Ruler 4 measurement modes: degree measurement, IN/FT pitch, mm/M pitch and slope percentage. High accuracy: the accuracy is ±0.1° to 0° and 90°, and the accuracy is ±0.2° to 1-89°. Resolution: ±0.01° to 0° and 90°, ±0.05° at any other angle. Large Clear LED Display with Audio Indicator The digital magnetic level has a large bright LED screen that can be automatically switched over, so you can easily read the measurement results even in the darkest space. In addition, we can also use the audio indicator to determine whether the horizontal ruler is in a horizontal or vertical position. Magnetic V-Groove Base The V-groove magnetic base is firmly attached to ferrous metal surfaces, such as pipes, steel frames and metalwork. Sturdy aluminium I-steel frame, neodymium magnets, rubber tips and dust/splash protection, suitable for harsh working environments Hold and Zero Function Hold function: the hold button can transfer the target value to other work areas. Reset function: it can be reset at any time by pressing the REF button, and the horizontal absolute measurement and relative measurement of the measured object can be performed. Attention Digital angle ruler is only suitable for two-axis measurement. When the third axis (i.e., the front and back of the level) and the horizontal bracket are less than 30 degrees, the screen will display the error message "Err". When the battery icon appears on the screen, it indicates that the battery is low and the battery needs to be replaced.
