1. Mechanical Scales: The scale has been designed with an accuracy of 0.1 grams and has a weighing range of 0.1 g 2610 g. It comes with weights to ensure precision and repeatability, and features a zero button to reset the scale before each measurement, minimizing errors and ensuring accurate data display. 2. Fast and Precise Weighing: Builtin magnetic damping mechanism keeps the pointer in balance and allows quick weighing results. The scale has clear and sharp markings that are not easy to wear and are easy to read, ensuring the visibility and accuracy of weight measurements. 3. Practical Weighing ToolsOur scale comes with 2 1000g weights and 1 500g weight. By hanging two additional weights at the same time, the capacity of the scale increases from 610g to 2610g, making it effective for learning weight measurements. 4. Easy to use: operation without batteries or external power supply. The scale features a 6inch diameter scale tray for placing items and a compact design that can be easily carried to classrooms, laboratories and other places.
