HR-A & HR-AZ Series Compact Analytical Balances
The HR-A Series delivers fast, accurate, and reliable analytical weighing in a compact footprint designed for space-constrained environments. Built on A&D Super Hybrid Sensor (SHS) technology, these balances provide consistent results for laboratory, quality control, QA, and production applications. The HR-AZ models feature highly reliable internal calibration with one-touch automatic operation to ensure consistent balance accuracy.
