The A&D HR-A and HR-AZ Series Analytical Balances combine speed, precision, and compact design for laboratories and research environments. With a 3-second stabilization time, these balances deliver quick and accurate results, boosting workflow efficiency.
HR-AZ models feature one-touch internal calibration, ensuring reliability and repeatability with minimal operator effort, while HR-A models use external calibration for flexibility. Both series include a removable breeze break with an anti-static coating and rotary sliding doors, optimizing space and protecting samples from environmental interference.
Designed for compliance-driven industries, the HR-A/HR-AZ balances are GLP/GMP/GCP/ISO compliant and include advanced weighing modes such as percentage, counting, and density determination. Lightweight yet durable, with an estimated weight of just 8.6 lb (3.9 kg), these balances are easy to set up and relocate when necessary.
