Yellowed crystals do not effect function
Indicators are cheap compared to other measuring tools so I just buy new ones.
I do not recommend this approach for high end tooling, gauge blocks, gauge pins, bore gauges, internal micrometers, external micrometers above 10", very small bore gauges, surface finish testers, hardness gauges and so on.
This indicator was purchased this year from MSC for $150.00, this is dirt cheap as far a metrology equipment goes.
I recently bought a new Tesa indicator to replace the old Mitutoyo one that worked well for 25 years, it stopped functioning so I gave it to another member here. The crystal was very yellowed but did not effect its use, buck up and live with it or buy a new one.
Ah, that's not yellowed, this is yellowed & grimy...
One is a Starrett, the other a Federal. Both are .0001"
