Our service process is designed to verify instrument performance in accordance with generally available manufacturer specifications and internal technical procedures. Following service, your equipment may be returned with a calibration label, calibration certificate, and related calibration data. If the unit does not successfully complete calibration, we can evaluate the repair requirements and provide a repair quotation for approval before proceeding.

Because the HP 81521B optical head is a legacy product, repair may not always be the most economical option. In some cases, replacement may be more practical than repair. Contact us with your model number and a brief description of the issue to request a calibration quote or repair evaluation.
