Certified. Secure. Compliant.

EN 15964 is the European metrological standard for professional breath alcohol testing instruments. It defines accuracy requirements, calibration protocols and operating conditions. A device certified to this standard produces results that are recognised by regulatory bodies, insurers and occupational health authorities across the EU and in many jurisdictions globally.

Yes. Sobber's combination of EN 15964-calibrated measurement, biometric identity verification and immutable timestamped audit trail provides a complete and unalterable chain of evidence. This documentation is designed to satisfy the evidentiary requirements of HR disciplinary procedures, insurance investigations and regulatory audits. The admissibility of evidence in criminal proceedings varies by jurisdiction and should be assessed with local legal counsel.

Facial images are encrypted using AES-256 and stored separately from test results. Access is role-gated — only designated HR or compliance officers can view biometric data. Employees have full rights to access, correct and delete their data. Regional data residency lets you keep EU employee data within EU infrastructure, Middle East data in-region, and so on. Sobber provides a full GDPR data processing agreement on request.

We provide a complete compliance package on request: CE Declaration of Conformity (with individual report numbers), EN 15964 calibration certificate, GDPR Data Processing Agreement, ISO 27001 security architecture documentation, and the full EN/FR instruction manual. Our team typically delivers this package within 48 hours of request.

Every 12 months or 1,000 tests — whichever comes first, in line with EN 15964 requirements. The AF-50AD displays the remaining days until calibration is due on startup and alerts the administrator via the dashboard when service is approaching. Sobber coordinates calibration with a local certified service partner to minimise operational downtime.
