This digital electronic balance scale is composed of a high-precision resistance strain sensor and a high-performance microcontroller. Due to air traffic control, our products are not equipped with batteries when they leave the factory. You can plug them in directly or buy batteries separately. With RS232 serial port. But does not include RS232 data cable. High-Precision Electronic Analytical Balance High Accuracy Measurements The digital electronic balance scale has a high, 0.01g precision. To ensure accuracy, the balance features a built-in level; adjustable leveling feet; an overload alarm; error indication; external calibration; and a removable plastic windshield. The linearity error is ±0.03g. A 500g standard calibration weight is included for your convenience. Intuitive User Controls The lab scale is user intuitive with easy control buttons designed to help you weigh items accurately and to save you time while doing so. The built-in counting function can total multiple pieces automatically potentially saving you time and money tallying inventory and other items. LED Display The analytical balance has a large, LED digital display for quick and easy readability. The precision instrument is built from lab-quality materials including a strong strain gauge sensor; a stainless steel weighing pan; and a durable, ABS body. RS232 serial port. RS232 serial port.
