Eupry is a Danish company and the data loggers they produce are made in Denmark. The national accreditation body for calibration in Denmark is DANAK, like UKAS is the national accreditation body in the UK. DANAK and UKAS recognise each other because there is a pan-European agreement between European accreditation bodies. Therefore, it should not cause any issues for an external quality auditor if your Eupry calibration certificates have a DANAK logo instead of a UKAS one.
