In professional measurement, we often need to measure some curved surfaces. The measurement results of traditional tape measures are usually not accurate and the operation is not simple enough. To solve this problem, we innovatively use the digital tape measure ruler and soft tape measure as a measurement set to help you complete all the measurement tasks in daily life, which can easily measure various curved surfaces and the flexible objects, easily helping you complete all kinds of measurement needs.THE TAPE MEASURE THAT CAN MEASURE CLOTHES - Compared with traditional tape measure, our tape measure set can not only perform the work of ordinary tape measure excellently, but can also measure irregular surfaces and shapes such as clothing, and is a fantastic technology equipment that can measure curved surfaces. This tape measure tool is ideal for professionals such as craftsmen and tailors.8 IN 1 HD LCD DISPLAY DIGITAL RULER - The digital electronic ruler supports 8 measurement methods, includes linear measurement, circular arc measurement, arbitrary curve measurement, irregular surface measurement, cylindrical diameter measurement, cumulative subtraction, measurement prompt sound, unit switching. Easily cover all measurement requirements.STRONG SEMICONDUCTOR MICROPROCESSOR - The electronic tape measure ruler equipped with ultra-low power consumption semiconductor microprocessor to achieve super long standby and battery life. Imported TDK inductor, capacitor, low inertia high precision digital encoder, high precision CNC processing of the metal shell and high precision nylon gear, to achieve long service life.99M ULTRA-LONG DISTANCE MEASUREMENT - The digital tape measure ruler supports single range 0-9 meters distance measurement, the cumulative distance measurement can be up to 99 meters. Millimeter-level measurement data makes the measurement results more accurate and precise. In addition, the electronic ruler also has 10 sets of historical records, you can check and view it at any time that making your measurement work more simple and efficient.STRICT QUALITY CONTROL & TEST - The soft tape measure is made of engineering plastics (ABS) and improved PU leather materials, which synthesis with Nano materials. The scale will not be deformed by long-term use. The tape measure had been tested and controlled strictly before deliver to you, so as to ensure the accurate.
