The BA-N Automatic Electronic Analytical Balance provides precise mass measurements with 0.1 mg readability across multiple capacity ranges up to 210g. This internal calibration analytical balance features a windshield-protected weighing chamber and stabilizes readings within 3 seconds, designed for quantitative analytical work requiring sub-milligram precision.
The instrument incorporates an 80mm diameter weighing pan within a draft shield measuring 175×165×230mm internal dimensions, providing protection from air currents during sensitive measurements. RS232C interface enables data logging and integration with laboratory information systems for automated record keeping and analysis workflows.
How It Works
The BA-N analytical balance operates using electromagnetic force restoration technology. An electromagnet generates a force that counteracts the gravitational force acting on the sample, with the current required to maintain equilibrium being proportional to the sample mass. This principle enables high-resolution mass measurements with minimal mechanical wear compared to traditional mechanical balance systems.
Internal calibration maintains measurement accuracy through automated adjustment using a built-in calibration weight. The system periodically verifies and corrects for drift in the measurement system without requiring external calibration weights. The draft shield minimizes air current effects that could destabilize readings, while vibration-dampening design elements reduce environmental interference.
Digital signal processing converts the analog measurement signal to a stable digital readout with 0.1mg resolution. The 3-second stabilization time reflects the instrument's ability to achieve measurement equilibrium rapidly while maintaining precision specifications across the full measurement range.

Practical Tips
Perform internal calibration after any significant temperature change or when moving the balance to ensure measurement accuracy.
Why: Temperature variations affect the electromagnetic force restoration system calibration.
Clean the weighing pan and draft shield regularly with appropriate solvents, ensuring complete drying before use.
Why: Residue buildup can affect measurement accuracy and introduce contamination between samples.
Allow samples and containers to reach thermal equilibrium with the balance environment before measurement.
Why: Temperature differences create air currents that destabilize readings despite draft shield protection.
Record multiple measurements for critical samples and calculate statistical parameters to assess measurement uncertainty.
Why: Replicate measurements provide confidence intervals and identify potential systematic errors.
If readings drift or fail to stabilize, check for air current sources and verify the balance is properly leveled.
Why: Environmental factors are the most common cause of measurement instability in analytical balances.
Use appropriate sample containers and avoid placing chemicals directly on the weighing pan surface.
Why: Chemical spills can damage the weighing mechanism and create safety hazards in the laboratory.
Document calibration dates and verification measurements to maintain traceability records for quality assurance.
Why: Calibration documentation supports analytical method validation and regulatory compliance requirements.

Compliance
What is the minimum sample size that can be accurately measured?
The balance provides 0.1mg readability with ±0.0002g repeatability, making it suitable for samples as small as 1-2mg with acceptable precision for most analytical applications.
How often should internal calibration be performed?
Internal calibration frequency depends on usage and environmental conditions, typically daily for routine analytical work or before critical measurements to maintain accuracy specifications.
Can the balance interface with LIMS systems?
Yes, the RS232C interface enables data transfer to laboratory information management systems and other data logging applications with appropriate software configuration.
What environmental conditions affect measurement accuracy?
Temperature fluctuations, air currents, vibration, and humidity changes can impact readings. The draft shield minimizes air current effects, but stable environmental conditions optimize performance.
Is external calibration weight verification recommended?
While internal calibration maintains routine accuracy, periodic verification with certified external weights confirms measurement traceability for quality assurance protocols.
What is the difference between the capacity options?
Models range from 100g to 210g maximum capacity while maintaining the same 0.1mg readability and precision specifications across all variants.
How does repeatability compare to linearity specifications?
Repeatability (±0.0002g) measures consistency of multiple measurements of the same sample, while linearity (±0.0003g) indicates accuracy across the full measurement range.
