Philips PM 5639 Display Unit Color Analyzer

Description

This CRT analyzer has been kept in climate controlled storage for 30 years and it’s finally time to let it go. It hasn’t been used in decades and thus the battery pack has corroded. The device still works with the power cable plugged in, but the battery does not store power.
I’ve cleaned the entire unit to the best of my abilities but there is still some dust on the cable as it is very difficult to clean thoroughly.
I no longer have a CRT tv so I wasn’t able to fully test whether or not it is still accurate, but it certainly turns on and all of the buttons works! The trigger on the gun portion requires extra pressure to activate, but it still activates.
Message me with any questions, thank you!
