FACTORY RECALIBRATION

All Hanna thermometers have been accurately pre-calibrated at the

factory. It is generally recommended to have all thermometers

recalibrated at least once a year. For an accurate recalibration,

contact your nearest Hanna Customer Service Center.

Hanna Accuracy Test Plugs provide a quick and easy way to check

the meter's accuracy by simply connecting these Test Plugs to the

probe connector of the meter. If the reading differs by more than

±0.4°C (±0.8°F) from the Test Plug value, the meter is due for

recalibration.

Choose the right Test Plug to suit your needs:
