2-in-1 Digital Angle Ruler with HOLD/REV, Zero Inversion, 200mm Stainless Steel Angle Measuring Tool with LCD Display (mm/inch) for Woodworking and Construction

【2-in-1 Fast and Accurate Angle Finder】 The combination of a digital angle finder and a stainless steel ruler allows for quick and accurate angle and length measurements (metric and imperial). The hinge mechanism on the angle ruler enables full 360-degree measurement of internal and inverted angles with an accuracy of ±0.2° and a resolution of 0.1°. 【Large LCD Screen】 This digital protractor is equipped with a large LCD screen, allowing you to obtain quick and accurate readings while working. 【Hold/Rev Function】 You can hold the reading by pressing the HOLD function button, and by pressing the REV function button, you can flip the screen for readings when measuring large angles. Easy to read, the laser-engraved scale is clear and precise. 【Zero Setting Function】Our angle finder also features a zeroing function, allowing you to set the zero point at any angle within the relative measurement range using a knob. The locking screw secures the reading at all times, and the tool will automatically shut off after 6 minutes of inactivity. 【Stainless Steel Angle Ruler】The protractor angle finder is made of durable stainless steel, which is more durable than plastic. Powered by a CR2032 button cell battery, it offers over 2000 hours of operation. The battery compartment is easily removable for push-pull replacement. (CR2032 battery included).
