A&D Weighing Borealis semi-microbalances are designed to handle complex weighing procedures with exceptional precision and user-friendly operation. The innovative draft shield is designed to prevent contaminant build-up, features automatic open/close doors, and flexible door positioning for maximum visibility of the weighing chamber. With expansive connectivity ports, GLP printing and administration-level access, Borealis semi micro balances ensure compliance and data protection.
Borealis balances are loaded with the latest technology, including internal repeatability checks, automatic diagnostic, impact detection and automatic internal calibration to ensure consistent and reliable performance. For critical weighing in industrial labs and university research departments, Borealis provides an excellent solution with the end-user in mind. Borealis semi-micro and microbalances are backed by a 5 year manufacturer's warranty for added peace-of-mind.
