HR-A & HR-AZ Series Compact Analytical Balances
The HR-A and HR-AZ Series Compact Analytical Balances deliver fast, accurate, and reliable weighing performance in a space-saving design. Built on A&D Super Hybrid Sensor (SHS) technology, these balances provide consistent weighing results in laboratory, quality control/QA, and production environments. The HR-AZ models feature highly reliable internal calibration with one-touch automatic calibration for consistent accuracy.

Key Features
- Rotary doors for space-efficient operation
- Breeze break top pivots left or right for easy access to flasks and beakers
- Detachable breeze break in seconds, even with heavy gloves
- Rugged, shatterproof breeze break with anti-static coating
- One-touch internal calibration on HR-AZ models
- 2-second stabilization time for increased productivity
- Ultimate clarity with reverse back-lit display
- Statistical calculation function, counting, % mode, user-defined units
- GLP/GMP/GCP/ISO compliant output
Space-Saving Design
Rotary doors ensure the balance requires no extra space when doors are open, making the HR-A Series ideal for tight confines such as glove boxes and fume hoods. The compact footprint allows for back-to-back setup of two balances on crowded benches. The pivoting breeze break top provides convenient access to beakers and flasks.
Suitable Environments
The anti-static, shatterproof breeze break makes the HR-A/AZ safe for sensitive applications where contamination is a concern:
- Pharmaceutical / FDA
- Food / HACCP
- Laboratory
- Quality Control / QA
- Production
