Series Overview

Calibration, stability and range control

External calibration: calibration is performed with an external certified calibration/control weight according to the laboratory SOP.

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 external calibration with a certified E2 calibration/control weight.

Applications, Delivery, Options and Calibration Weights

SIRET analytical balance | external calibration | touch screen | 0.1 mg readability

Built-in applications and operating modes

Standard analytical weighing: high-precision weighing for laboratory samples.

Parts counting: counting down to 1 mg in laboratory conditions; 10 mg minimum weight, resolution counting 210,000.

Percent weighing: compare measured mass to a reference.

Density weighing: direct reading function for density workflows with optional hydrostatic set.

Animal weighing: supports unstable sample measurement.

Check and target weighing: upper/lower limit checks, target weighing, summarization, gross/net/tare and peak hold.

Optional accessories

Optional thermal printer for laboratory balance

OIML E2 calibration weight — Optional OIML E2 calibration / control weight

Ordering note: Source PDF recommends a 200 g E2 class calibration/control weight. Confirm required nominal masses, E2 certificates and calibration/control-weight procedure for the selected SIRET model and laboratory SOP.
