Approx 65 percent of tonometers have calibration errors. Tonometers should be checked at least once a month. If errors are present they should be sent in to factory-trained personnel to clean and calibrate. Optitech Usa offers this service on all models of Applanation Tonometers.
These are the steps Optitech USA takes to calibrate your tonometer:
- The unit is first opened and checked for wear and tear.
- When no parts need to be replace the calibration process begins.
- Upon completion of the calibration process the unit is cleaned externally.
- The unit is next repackaged and returned to you.
