Recertification of Glass Filters

As is the case for all measuring devices, the glass filters used to verify spectrophotometers must also be checked and recertified at regular intervals.

In general, a recertification interval of 12 months is recommended for checking and recertifying glass filters during the first two years of use, with an interval of 24 months thereafter.
