Series Overview
Calibration, stability and range control
Internal auto calibration: automatic calibration can be triggered by temperature, time, condition change or manual operation.
Dual measuring range: automatic dual-range and double-precision function supports efficient handling for small samples.
Temperature compensation: real-time compensation improves analytical stability during routine use.
Anti-vibration filtering: seven-stage adjustable filtering helps adapt the balance to different laboratory environments.
Data handling and usability
PC data workflow: optional communication software can collect data and control the measurement process.
Cursor output: balance measurement data can be written to Excel, Word and other documents following the cursor.
Colour touch screen: direct access to frequent settings with a high-resolution LCD touch display.
Built-in records: date, time and temperature display are adjustable for traceable weighing routines.
Key product features from source PDF
Sensor: electromagnetic monoblock force compensation.
Windshield: glass protective case opens from three sides and reduces air-flow influence.
Interfaces: USB and RS232 communication ports for peripheral equipment.
Units: more than 20 shieldable units including mg, ct, oz and lb.
Operation: automatic mode lock at switch on/off, leveling bubble and portable hand handle.
System: multi-user management, standby mode and fully automatic internal calibration.
