Primary Applications
- Laboratory
- Quality Control / QA
- Production
Suitable for Sensitive Environments
The rugged, shatterproof breeze break with anti-static coating makes the HR-A/AZ safe for challenging applications where contamination is a potential concern:
- Pharmaceutical / FDA
- Food / HACCP
Space-Saving Design
Rotary doors mean that the balance takes up no extra space when the doors are open. The HR-A Series is perfectly at home in the tight confines of glove boxes and fume hoods. Crowded academic lab benches are no problem: set-up 2 balances back-to-back. The top of the breeze break also pivots open (left or right), allowing easy access to beakers and flasks.
Ease of Use
The breeze break detaches in seconds even with heavy gloves, making cleaning easier and enabling top-loading operation. The 2-second stabilization time increases productivity by delivering fast results. The HR-A/AZ lets you perform frustration-free weighing down to a resolution of 0.1 mg.
