11. ANALYZER ANNUAL RECALIBRATION AND SERVICE
Although sensor life is typically more than two years, the analyzer should be re-calibrated and
serviced annually to stop any long-term sensor or electronics drift or accidental damage.
Local regulations may require more frequent re-calibration.
Contact us or an authorized repair center for more information.
