24 Month Warranty

Di-Log instruments are subject to stringent quality controls.
If in the course of normal daily use a fault occurs we will
provide a 24 month warranty (only valid with invoice). Faults
in manufacture and materials defect will be rectified by us
free of charge, provided the instrument has not been
tampered with and returned to us unopened. Damage due
to  dropping, abuse or misuse is not covered by the warranty.

Outside the warranty period we offer a full repair and
re-calibration service.
