Precisa Series 390 Semi-Micro and Analytical Balances

Precisa Series 390 Semi-Micro and Analytical Balances: High-Precision Metrology and Automation Systems for Compliant Laboratory Operations

The Precisa Series 390 Semi-Micro and Analytical Balances represent a premium line of Swiss-engineered laboratory instruments designed to address critical precision bottlenecks in commercial, pharmaceutical, clinical, and industrial research environments. In high-throughput testing and regulatory compliance workflows, minute environmental variances, airborne drafts, static accumulation, and operator mechanical fatigue can quickly compromise mass determination integrity. The Series 390 completely mitigates these precision hazards by integrating advanced electronic stabilization systems, including automatic self-calibration systems and a dynamic draft shield that eliminates physical touch contamination and human measurement errors.

Constructed specifically to withstand severe multi-user demands while meeting stringent laboratory workflows, this series provides exceptional ergonomics and data traceability. Featuring the lowest weighing pan access level available on the analytical market, it lowers operator arm stress and increases sample handling safety. The design utilizes a frameless, tool-free draft shield that dismantles completely within seconds, allowing all glass components and the stainless steel pan to be directly cleaned in a standard laboratory dishwasher. With embedded software applications like Buoyancy Error Suppression Technology (BEST) and built-in audit trails, this balance series satisfies the rigorous infrastructure tracking requirements of facility directors and procurement officers.

Key Benefits:

• Ultimate Low-Access Ergonomics: Engineered with the lowest weighing pan access level on the industrial market, providing maximum operator comfort and stability during long sample preparation sequences.
• Automated Motorized Draft Shield: Features an advanced motorized draft shield (MDS) on select models driven by programmable touchless sensors (TLS) to facilitate hands-free opening, taring, and printing commands.
• Frameless Barrier-Free Viewing: Outfitted with a high-clarity, frameless glass structure that grants an unobstructed view of the weighing chamber and completely streamlines sample insertion.
• Rapid Dishwasher-Safe Cleanup: Designed with an innovative tool-free disassembly mechanism, allowing lab technicians to detach all draft glass panels and components in seconds for rapid mechanical sanitation.
• Buoyancy Error Suppression Technology: Integrates proprietary BEST software algorithms paired with an Ambient Observation System (AOS) to automatically calculate and correct environmental air density fluctuations.
• Self-Linearization System Protection: Outfitted with an automated internal calibration system (SCS) that adjusts dynamically to real-time temperature or barometric pressure shifts, ensuring uncompromised accuracy.
• Electrostatic Cancellation Performance: Utilizes an integrated AC pulse ion neutralizing system (ECS) on high-end configurations to instantly eliminate electrostatic charges on sample containers upon draft shield closure.
