HZY-223/323-HZY-3003 Dual-Range Precision Balance, 1 mg Readability (CAT#: STEM-BC-1658-ZJF)

This advanced precision balance is designed for high-capacity weighing with readability down to 1 mg. It uses a monolithic precision mass sensor to combine responsive indication with stable measurement behavior. The HZY-223/323 and HZY-523/623 models provide automatic dual-range and dual-resolution operation. The high-resolution color touchscreen displays weighing results, settings, and a real-time capacity progress bar. User-defined intelligent internal calibration can be triggered by temperature change or elapsed time while the balance is idle. Real-time temperature compensation, seven-level vibration filtering, and adjustable stabilization time support consistent operation. The instrument provides percentage weighing, density determination, animal weighing, parts counting, cost calculation, checkweighing, tare-related weighing, peak hold, and accumulation. Computer control and direct data entry into compatible spreadsheet and document software are supported through installed software. USB and RS232 ports enable communication with computers and peripheral devices.
