Annual Service & Re-Certify - Kane 905 Manual

12. ANNUAL SERVICE & RE-CERTIFY
Whilst the sensors have an expected life of more than two years in
normal use it is recommended that the analyser is serviced and
re-certified at least annually. This is so that long term drift on the sensors
and electronics can be eliminated. Local regulation may require more
frequent re-calibration and users should check with appropriate
authorities to ensure they comply with relevant guidelines.
