OPTIONAL ACCESSORIES AND CALIBRATION / CONTROL WEIGHTS
Printer, hydrostatic set and OIML E2 calibration/control weight
Because SIRET analytical balances use external calibration, the calibration/control weight is a core part of the weighing configuration. The source specification recommends a 200 g OIML E2 calibration/control weight; the final nominal mass, E2 certificate, calibration frequency and acceptance limits should be defined according to the selected SIRET model and laboratory quality system.
OIML E2 calibration/control weights
Recommended for external calibration, analytical-balance control routines, audit support and documented verification points where E2 class weights are required.
Optional thermal printer
Supports printed measurement records where laboratory procedures require direct printout of weighing results.
Configuration logic
- Define the expected weighing range and routine minimum sample mass.
- Confirm whether dual-range operation is needed for the selected model.
- Select the E2 calibration/control weight according to SOP verification points.
- Confirm E2 certificates, printer, software and hydrostatic set before ordering.
Ordering note: optional accessories and E2 weights are not automatically included in the standard SIRET delivery. Printer, hydrostatic set, software, communication accessories, E2 weights, certificates and documentation requirements should be confirmed before the final quotation.

Applications and operational value
Analytical laboratory weighing
SIRET analytical balances support 0.1 mg weighing for laboratory samples, reagents, reference materials and routine analytical workflows.
External calibration workflow
External calibration allows laboratories to define the calibration/control-weight procedure, nominal masses, certificates, frequency and acceptance limits according to SOP requirements.
QC and documented routines
USB/RS232 communication, optional printer and optional software support documented QC, sample preparation and laboratory data workflows.
Advanced weighing modes
Percent weighing, check weighing, target weighing, animal weighing, density workflows and parts counting extend the SIRET series beyond standard mass measurement.
How to select the appropriate SIRET configuration
When selecting a SIRET analytical balance, start with the expected weighing range, typical sample mass, tare vessel mass and routine minimum sample weight. The 120 g, 220 g, 320 g and 400 g models cover different capacity requirements while preserving 0.1 mg readability.
For documented laboratory operation, also define the external calibration routine, E2 calibration/control-weight procedure, printer or PC data-output needs, software expectations, hydrostatic density requirements and certificate requirements. COLO.Science can help confirm the SIRET model, accessories and documentation package before quotation.
SIRET analytical balances for 0.1 mg external-calibration weighing
SIRET analytical balances are suitable when laboratories need stable 0.1 mg weighing with a modern touch-screen interface, external calibration and protection from air-flow influence. The glass windshield, electromagnetic monoblock force compensation and temperature compensation support repeatable weighing in routine analytical environments.
In practical use, SIRET performance depends on correct installation, stable temperature, suitable bench conditions, proper levelling, warm-up time and an appropriate E2 calibration/control-weight procedure. Optional printer, software and hydrostatic accessories can be added according to laboratory method and documentation requirements.
