Filters for instruments

Filter disks are used in tube receivers to prevent flow path blockages. Instrument filters should be checked and replaced regularly as part of a routine maintenance plan. Split tubes can be used multiple times, but should be routinely replaced – Markes recommends at least every 12 months. Split filter tubes should never be desorbed.

- User-replaceable

- Common parts for all instrument series
