Swiss Made Precision for Laboratories Where Every Measurement Matters

The Precisa HF Analytical & Semi-Micro Balances represent the most advanced product line within the Precisa 390 Series. Designed and manufactured according to the renowned Swiss Made standard, they have been developed for laboratories where uncompromising precision, process integrity and long-term measurement reliability are fundamental requirements.

Every analytical result has consequences. Whether supporting pharmaceutical development, validating research data or ensuring product quality, reliable weighing forms the foundation of confident scientific decisions. In these environments, exceptional readability alone is not enough. Laboratories require instruments capable of delivering the same level of precision consistently, regardless of environmental influences or daily operating conditions.

This is precisely the philosophy behind the Precisa HF product line.

Rather than focusing exclusively on weighing performance, the HF platform has been engineered to optimise the complete analytical workflow. Advanced weighing technology, intelligent automation and integrated assistance systems work together to minimise operator influence, stabilise weighing conditions and improve confidence in every measurement.

Engineered for laboratories operating under the highest standards

Modern laboratories operate within increasingly demanding regulatory environments. Pharmaceutical manufacturing, analytical chemistry, biotechnology and accredited testing laboratories all depend on measurement systems that deliver reliable, traceable and fully reproducible analytical results.

The Precisa HF product line has been developed specifically for these environments.

Its sophisticated weighing technology is supported by intelligent monitoring systems that continuously assist the user throughout the weighing process. Environmental influences are monitored, critical operating parameters are automatically controlled and routine procedures are simplified through intelligent automation.

The result is a weighing platform that supports both laboratory efficiency and long-term measurement confidence.

Supporting the complete analytical workflow

Analytical weighing involves far more than determining a numerical value.

Sample preparation, environmental stability, operator interaction and process consistency all influence the final result. The Precisa HF balances have therefore been designed as complete laboratory instruments rather than standalone weighing devices.

From automatic calibration routines and intelligent environmental monitoring to touchless operation and motorised draft shield doors, every function has been developed with one objective: maintaining stable weighing conditions while reducing unnecessary operator intervention.

This integrated approach enables laboratories to standardise weighing procedures, improve workflow efficiency and support consistent analytical performance across the entire organisation.

Designed around laboratory professionals

The usability of a laboratory balance directly influences both productivity and measurement quality.

The HF product line has therefore been developed around the practical requirements of laboratory professionals working in demanding analytical environments.

The exceptionally low weighing pan simplifies sample handling while reducing unnecessary movement during repetitive weighing procedures. The large high-resolution touchscreen provides immediate access to weighing applications, user profiles and instrument settings through an intuitive interface designed for everyday laboratory use.

Depending on the selected model, touchless sensors and motorised draft shield doors further improve workflow efficiency by reducing physical interaction with the instrument during critical weighing operations.

The result is a laboratory balance that combines exceptional analytical performance with outstanding operator comfort throughout the working day.

Advanced Technologies for Reliable Analytical Performance

Every technology integrated into the Precisa HF product line has been developed with a single objective: ensuring that every measurement can be reproduced with confidence under real laboratory conditions.

Rather than adding features for their own sake, Precisa combines advanced weighing technology with intelligent monitoring and automation systems that actively support laboratory professionals throughout the complete analytical workflow.

The result is a weighing platform designed to minimise environmental influences, reduce operator intervention and maintain consistent measurement quality over many years of operation.

Touchless Sensor (TLS)

Laboratory workflows often involve hundreds of weighing procedures every day. Repeated physical interaction with the balance can interrupt the weighing process, introduce unnecessary disturbances and increase the risk of contamination.

The Touchless Sensor (TLS) allows selected functions to be activated through a simple hand movement without touching the instrument. Depending on the configuration, operators can open draft shield doors, initiate tare functions or trigger programmable commands while maintaining a controlled working environment.

In pharmaceutical production, cleanrooms and highly regulated laboratories, touchless operation contributes to improved workflow efficiency while reducing unnecessary contact with the balance.

Motorised Draft Shield Doors

Air movement remains one of the most significant sources of weighing instability during high-resolution analytical measurements.

Motorised draft shield doors open and close smoothly with consistent speed, reducing mechanical disturbances during sample placement while improving repeatability throughout routine laboratory procedures.

The controlled movement of the draft shield also supports automated weighing workflows and contributes to greater consistency between different operators.

Electrostatic Cancellation System (ECS)

Electrostatic charges can significantly influence the weighing of lightweight samples, powders and filter materials.

The integrated Electrostatic Cancellation System (ECS) helps neutralise electrostatic influences within the weighing chamber before they affect the measurement itself.

By reducing electrostatic interference, laboratories benefit from improved weighing stability, faster stabilisation times and greater confidence when working close to the balance's readability limits.

Ambient Observation System (AOS)

Environmental conditions continuously influence high-precision weighing.

Temperature fluctuations, humidity and atmospheric pressure all contribute to measurement uncertainty when working at the highest levels of analytical performance.

The Ambient Observation System (AOS) continuously monitors these environmental parameters, allowing laboratories to document weighing conditions while supporting traceability and long-term quality assurance.

For laboratories operating under GLP, GMP and ISO requirements, this additional environmental documentation contributes to improved process transparency.

Self Calibration System (SCS)

Maintaining analytical accuracy requires regular calibration.

The Self Calibration System (SCS) performs automatic internal calibration whenever predefined temperature changes or programmed time intervals occur.

Because calibration is performed automatically using the internal calibration weight, laboratories benefit from consistent weighing performance without interrupting routine analytical work.

Self Linearization System (SLS)

Calibration verifies a reference point.

Linearisation verifies the entire weighing range.

The Self Linearization System (SLS) continuously maintains weighing accuracy across the complete measuring capacity, ensuring that analytical performance remains consistent regardless of sample weight.

For laboratories performing measurements across different weighing ranges, this contributes to greater confidence in every analytical result.

Electronic Levelling Assistance

Correct levelling is essential for high-resolution laboratory balances.

The integrated electronic levelling system continuously monitors the installation position of the instrument and assists laboratory personnel whenever correction becomes necessary.

Maintaining proper levelling ensures that the balance continues operating within its specified performance throughout daily laboratory use.

High-Resolution Touchscreen Interface

The large colour touchscreen provides fast and intuitive access to weighing applications, user profiles, reporting functions and instrument settings.

Its modern interface has been developed specifically for professional laboratory environments, allowing users to navigate complex analytical workflows quickly while reducing training requirements for new personnel.

The display remains clear and responsive even during intensive daily operation.

Laboratory Connectivity

Modern laboratories require seamless integration between analytical instruments and digital laboratory environments.

The Precisa HF product line supports a range of communication interfaces including:

• USB Host
• USB Device
• RS232
• Ethernet

These interfaces simplify data transfer, printer connectivity and integration with laboratory information management systems (LIMS), supporting efficient documentation and regulatory compliance.
