HR-A & HR-AZ Compact Analytical Balances
The HR-A and HR-AZ Series Compact Analytical Balances deliver fast, accurate, and reliable performance based on A&D Super Hybrid Sensor (SHS) technology. These balances provide consistent weighing results in laboratory, quality control, QA, and production environments while maintaining a compact footprint ideal for space-constrained applications.

Space-Saving Design
The rotary door design ensures no additional space is required when doors are open, making these balances ideal for glove boxes, fume hoods, and crowded laboratory benches. Multiple balances can be set up back-to-back for efficient use of limited bench space. The breeze break top pivots left or right to allow easy access to flasks and beakers.
Enhanced Productivity
The breeze break detaches in seconds, even while wearing heavy gloves, simplifying cleaning and enabling top-loading operation. With an approximately 2-second stabilization time when set to FAST mode under good environmental conditions, the HR-A/AZ delivers frustration-free weighing down to 0.1 mg resolution.
