0.001g High Precision: This analytical balance has 8 optional ranges from 200g-600g; Minimum Weighing: 10mg; Accuracy: +/- 0.004g. To ensure to get the results quickly and accurately, the precision scale is equipped with an upgraded high-sensitivity build-in sensor, adjustable feet, level bubble, overload alarm, error indication, and external calibration. Material: High-quality materials are chosen for their durability and reliability. The round weighing pan of our scale is constructed from 304 stainless steel materials that provide stability and support for various weights. Its surface is designed to resist corrosion, making it suitable for use with a wide range of materials, including chemicals, powders, liquids and also jewelry, screws, and etc. Features: 1. This scale features a high-definition LCD display, easy to read accurately and clearly in the dark, and easy to operate. 2. Customize units setup 14 units selectable: g (gram), ct (carat), g(%), oz (ounce), ozt, N, lb (pound), dr, GN (grain), tlT, T, T/A/R, %, dwt. 3. Windshield, aiming to avoid external influences like wind and make the weighing results more accurate. 4. Functions: This analytical balance has multiple functions of tare, counting and fault visualization. Application: This lab scale is widely used in laboratories, schools, enterprises, jewelers, scientific research institutes, and other units to accurately measure the quantity and quality of objects Two Power Supply Ways and Calibration Weight: This digital scale can be powered by both a power cord and lithium battery (NOT INCLUDED) to work wherever AC power supply is unavailable. Also included 500g calibration weight makes it easy to recalibrate your laboratory-scale without buying extra weights.
