OPTIONAL CALIBRATION AND CONTROL WEIGHTS
Optional weights for external calibration and routine verification
CENTA balances use external calibration, so suitable calibration or control weights should be selected when preparing the quotation. The weight package depends on the selected model, typical working range, tare mass, SOP verification points, OIML class, certificate requirement and local quality procedure.
M1 weight set 1 mg–500 g
Optional 24-piece M1 set for lower and middle verification points, multi-point checks and routine laboratory control procedures.
SKU: PRO5291 · Open product
M1 calibration weight 1 kg
Optional 1 kg M1 weight for routine checks or calibration support within defined laboratory and quality-control procedures.
SKU: PRO5284 · Open product
Selection logic
- Select weights close to the typical sample and tare range.
- Define calibration and routine-check points in the SOP.
- Add larger nominal masses for higher-capacity CENTA models when required.
- Confirm OIML class, certificate and handling method before ordering.
Ordering note: calibration weights are optional accessories and are not automatically included in the standard CENTA delivery. Nominal mass, class, certificate, calibration procedure, printer, software and accumulator should be confirmed before the final quotation.
