Measurement accuracy is only meaningful when it is traceable. Zurich Instruments calibrates every instrument before shipment, and recommends recalibration every two years to ensure continued operation within specifications. This interval reflects the drift characteristics of precision electronic components over time, a standard practice in high-quality instrumentation. Our calibration package is instrument-specific and includes full documentation, so your measurements stay traceable and your setup audit-ready. A calibration package includes: Instrument calibration valid for 2 additional years Extended calibration report 2 weeks of turnaround time at best effort Visual and mechanical inspection 6-month warranty extension (within 7 years) Worldwide return shipments
