SANAS-Accredited and Traceable Calibration Services
HJR Microptic is a SANAS-accredited calibration laboratory, providing accredited calibrations within our approved scope of accreditation. In addition, we offer traceable calibration services for equipment outside our accredited scope where appropriate. All calibrations are performed using standards that are regularly calibrated and linked through an unbroken chain of comparisons to national and internationally recognised measurement standards. This ensures measurement traceability, accuracy, and confidence in calibration results, whether an accredited certificate or a traceable calibration report is required. Our customers benefit from calibration services that support quality management systems, regulatory requirements, and reliable measurement performance across a wide range of applications.
ISO/IEC 17025
International Laboratory Standard
Calibration laboratories operate under ISO/IEC 17025, the international standard for testing and calibration laboratories. Unlike ISO 9001, which focuses on general quality management, ISO/IEC 17025 assesses both the quality system and the technical competence of the laboratory, ensuring accurate, traceable, and reliable calibration results.
Flexible Solutions
Flexible Calibration Solutions to Suit Your Requirements
HJR Microptic offers both on-site (in-house) and laboratory-based calibration services, allowing customers to choose the option that best suits their operational needs.
On-Site Calibration
Calibration at Your Premises
For equipment that is difficult to transport, forms part of a production process, or where downtime needs to be minimized, our qualified technicians can perform calibrations at your premises. This allows your equipment to remain on-site while ensuring compliance and measurement accuracy.


Laboratory Calibration
Controlled Laboratory Environment
Customers may also deliver their equipment to any of our branch offices or directly to our Head Office. The equipment will be calibrated in our controlled laboratory environment using accredited standards and specialised calibration equipment. Once completed, the equipment and calibration certificates will be returned to the customer.
Whether calibration is performed at your facility or in one of our laboratories, you can expect the same professional service, technical expertise, and commitment to quality from HJR Microptic.
